Bump to xamarin-android-api-compatibility/master/9cfa6cc9 #1078

jonpryor · 2017-12-06T22:25:45Z

We found that xamarin-android-api-compatibility wasn't actually
performing the inter-API-level checks, meaning an important API
compatibility check wasn't being performed.

Bump to xamarin-android-api-compatibility/9cfa6cc9 so that
inter-API-level checks are properly performed.

@atsushieno: I'm not sure why android/view/animation/Transformation.TYPE_ALPHA was changed from -1 to 19 in commit a301764; how was that determination made?

Is there anything else that should be re-investigated for consistency? (Meaning, how confident are we that only the Transformation.TYPE_* members were erroneously enumified in API-19+?)

atsushieno · 2017-12-07T00:58:01Z

That is a bad sign, I'll take a look. They are automatically generated so if such a problem exists then there could be issues on other enums.

Are there any difference between xamarin-android and monodroid on API compatibility tests?

atsushieno · 2017-12-07T00:59:54Z

(And the changes themselves here won't be applied, because they are automatically generated.)

The fun fact: those constants were actually NOT constants until API Level 18(!)

They became constants since API Level 19. Therefore they are egarded as new in API Level 19. And technically it is possible that each device has different values for those non-final static fields.

What would we like to deal with them? My suggestion is just throw away possibility on having different values for those non-constant fields and treat them as constants. That will need some special trick or manual constant-ification work.

It matches your currently suggested changes, but you may have different opinion now that the situation became clearer.

Sounds good to me; API-18 is 0.9% of the Google Play Store market.

Unfortunately, that's only the beginnings. This PR also updates xamarin-android-api-compatibility to actually run the inter-API-level differences. The results are not pretty:

I have not read or reviewed the above; I'm just copy & pasting from the build log.

That said, monodroid is currently referencing commit bf12270, and is not getting any of the above errors.

Let's please stop mixing two irrelevant problems at once. Enums are enums, other changes such as base types etc. are different issues. My scope is about the problematic enum part.

…s too. At 9a73c4c we became much more precise about enumification, because formerly we only pull int constant information through DroidDoc only in the latest API. Besides, we had been precise on which int fields are final and which aren't, in API XML metadata. Since we switched the information source to API XML metadata, such final fields that were NOT final are strictly converted to enums only in the constant-ified API Level. That was regarded as regression at dotnet#1078 . The solution to this situation is: treat them as constants. To do so, now generate-const-list-2.cs is changed to NOT check if an int field is final or not, until at the merge phase. Then we filter out those non-constant fields (which are not much). This uncovers those "formerly non constant" fields too. Fortunately such fields didn't exist other than the ones at PR dotnet#1078 mentioned (this generate-const-list-2.exe now prints out such fields now.)

We found that xamarin-android-api-compatibility wasn't *actually* performing the inter-API-level checks, meaning an important API compatibility check wasn't being performed. Bump to xamarin-android-api-compatibility/9cfa6cc9 so that inter-API-level checks are properly performed.

Agreed. You fixed the enum binding problem in PR #1085, so now this PR is just a xamarin-android-api-compatibility bump.

Analysis of current errors:

(insert crying here)

Why Didn't monodroid Report These?

I started digging into inter-API-level diffs because of check-api failures on a monodroid PR. Interestingly, the monodroid failures do not include the set of current errors; monodroid doesn't report these errors.

This is because monodroid has a separate set of checks, and greps for >Removed to detect API breakage, not data-is-breaking.

Which means we have unreported breakage.

(Insert crying here.)

Worse (?!), I don't yet know how long this breakage has existed.

`virtual` changed to `abstract`

<h3>Type Changed: Android.Text.ClipboardManager</h3>
<p>Modified properties:</p>
<pre>
<div data-is-breaking>	public <span class='added added-breaking-inline'>abstract</span> bool HasText { get; }
</div><div data-is-breaking>	public <span class='added added-breaking-inline'>abstract</span> Java.Lang.ICharSequence TextFormatted { get; set; }
</div></pre>

Most of the reported breakage, by far, is adding abstract to a method, as above.

virtual changed to abstract

My guess on the culrit is my change here https://github.com/xamarin/xamarin-android/pull/662/files#diff-e866706b2ad1cc482e160a559aed991a

jonpryor · 2017-12-07T20:36:45Z

Next question: Do these changes matter?

Rephrased: were these changes introduced in d15-6, or do they also exist in d15-5 (and before?). If they exist in d15-5, that suggests that we can just ignore them (can we?).

Type Changes

<h3>Type Changed: Android.Telecom.RemoteConference</h3>

<pre>
<div data-is-breaking>	public <span class='removed removed-inline removed-breaking-inline'>CallProperty</span> <span class='added '>ConnectionProperties</span> ConnectionProperties { get; }
</div></pre>

This change between v7.0 and v7.1 also exists in d15-5.

@atsushieno: What should we do here? It looks like the Android.Telecom.RemoteConference.ConnectionProperties property was introduced in API-24 (v7.0), so I think we want to change v7.0 to use ConnectionProperties instead of CallProperty.

jonpryor · 2017-12-07T20:52:15Z

`virtual` changed to `abstract` Analysis

The API BREAK BETWEEN v2.3 and v4.0.3 section is identical to d15-5; these changes aren't new.

The API BREAK BETWEEN v4.0.3 and v4.1 section is identical to d15-5.

The API BREAK BETWEEN v5.0 and v5.1 section is identical to d15-5.

The API BREAK BETWEEN v5.1 and v6.0 section is identical to d15-5.

jonpryor · 2017-12-07T20:57:20Z

This is where telemetry would come in handy. Best reasons I can think of for this not having bitten us already are:

The actual method signatures haven't changed (except the API v7.0 to v7.1 changes), so assemblies referencing those members will still load.
The last API level with any such change is v6.0 (API-23); we haven't introduced abstract anywhere since then -- API-24+ is "stable", and, as I understand it, any app that is using the Support libraries needs to be using API-26 (soon to be API-27!) in order to use the support libs.

Meaning the only people this will impact are those using one of those ~95 members and not using the Support libraries, which could be a very small number of people.

The fact that all of these issues suggests that we should just ignore them for now, except the API-25 Android.Telecom.RemoteConference.ConnectionProperties change.

atsushieno · 2017-12-07T22:33:52Z

On android.telecom.RemoteConference.getConnectionProperties():

The constants that consists of Android.Telecom.RemoteConference.ConnectionProperties enum type are from android.telecom.Connection.PROPERTY_* constants which are *from API Level 25.
That means, Google didn't indicate any constants for that method, therefore it was mapped to CallProperty enum (because, it's almost obvious from the name! and unlike these days DroidDocs were not reliably pointing to the target constants to use).

They are thus mapped to different enums.

What's the actual impact due to current state?

Apps that explicitly targets Android 7.0 and referencing some library that references this method will result in MissingMethodException

What's the impact if we change that?

Apps that explicitly targets Android 7.0 and referencing some library that already referenced this method (with CallProperty) will result in MissingMethodException.

Either bites. And either don't bites us by NoSuchMethodException in Java land because they are both int.

I thought of two "solutions":

(1) leave it as is and for anyone who don't use Support libraries and sets the target framework to 7.0, tell them to "use 7.1" (because its impact is relatively small).
(2) mark those constants as if they existed since API Level 24.

Maybe (2)? Because it should not be difficult to give fake API information in src/Mono.Android/metadata.

Context: dotnet/android#1078 xamarin-android uses `mono-api-html` and `mono-api-info` in order to perform API comparisons; see e.g. 4e45904. A recent problem has arisen regarding "inter-API-level diffs": there are many API changes which we consider to be acceptable, and thus would like to ignore. Unfortunately, `mono-api-html` doesn't support ignoring many of these constructs, e.g. base class changes: <h3>Type Changed: Android.Preferences.CheckBoxPreference</h3> Modified base type: <span class='removed removed-inline removed-breaking-inline'>Android.Preferences.Preference</span> <span class='added '>Android.Preferences.TwoStatePreference</span> and property type changes: <h3>Type Changed: Android.Views.InputEvent</h3> <p>Modified properties:</p> <pre> <div data-is-breaking> public <span class='added added-breaking-inline'>abstract</span> int DeviceId { get; } </div><div data-is-breaking> public <span class='added added-breaking-inline'>abstract</span> InputSourceType Source { get; } Overhaul the `mono-api-html` "ignore" infrastructure: * Introduce ignore "scoping". Previously, the ignore options would only match the *member* text against any provided regular expression. Thus, `mono-api-html -r ToString` would ignore *all* members containing `ToString`. Furthermore, there was no way to restrict the ignore to a particular type. Expand the regex semantics so that the declaring type is used as a "prefix" for the to-be-matched text. For example, if a class `Example` is removed, `mono-api-html` will now match the following value against any `-r` regular expressions: Example: Removed type * Add a `mono-api-html -v` option, to control output verbosity. When specified, `mono-api-html` will print out available `-r`/etc. option values: $ mono-api-html expected.xml new.xml -v Possible -a value: Android.Resource: Added fields: public static const int AccessibilityEventTypes; Possible -r value: Android.Preferences.CheckBoxPreference: Modified base type: 'Android.Preferences.Preference' to 'Android.Preferences.TwoStatePreference' Possible -r value: Android.Views.InputEvent: Modified properties: public int DeviceId { get; } Possible -n value: Android.Views.UnavailableException: Added type ... Additionally, allow `mono-api-html` to take a `Mono.Options.ResponseFileSource`, which allows `@response-files` to be used as command-line options.

commit d3ad544 Author: Dean Ellis <dellis1972@googlemail.com> Date: Wed Feb 21 16:36:10 2018 +0000 [Xamarin.Android.Build.Tasks] Update `CalculateProjectDependencies` to match spec (#1323) The `GetAndroidDependencies` target (f9b2c97) is intended to be called by an IDE on project-load, so that the IDE can install project dependencies "in the background," and ideally have the dependencies installed before the project is actually built. As such, the semantics of the `@(AndroidDependency)` output item group need to be agreed upon by xamarin-android, the IDEs, and whatever the IDEs use to actually install the dependencies. The `%(AndroidDependency.Identity)` values need to be well-defined and consistent across these three different libraries. In commit f9b2c97, certain values would have a version number "embedded" within `%(AndroidDependency.Identity)`, using a `;` to separate the name from the version, e.g. `build-tools;26.0.1`. Use of `;` was chosen because that made it easier for the package installation code to use (e.g. it would be identical to what the Android SDK `sdkmanager` utility expects). Unfortunately, the use of `;` was counter to the [spec][spec], and also looks "weird" in the context of MSBuild, as `;` is *also* the item group separator. Change the version separator to instead be a `/`. This "looks" better and is also consistent with the [installer manifest][manifest] schema that we will use, wherein `%(AndroidDependency.Identity)` matches a `//xamarin-android/*/@filesystem-path` attribute value: <xamarin-android sdk-version="0.0.0" generated-on="Tue, 20 Feb 2018 21:16:01 GMT"> <platform-tools filesystem-path="platform-tools" path="platform-tools" revision="27.0.1" manifest-url="https://dl.google.com/android/repository/repository2-1.xml" description="Android SDK Platform-Tools" obsolete="False" preview="False" license="android-sdk-license" original-type="generic:genericDetailsType">  </platform-tools> <build-tool filesystem-path="build-tools/27.0.3" path="build-tools;27.0.3" revision="27.0.3" manifest-url="https://dl.google.com/android/repository/repository2-1.xml" description="Android SDK Build-Tools 27.0.3" obsolete="False" preview="False" license="android-sdk-license" original-type="generic:genericDetailsType"> </build-tool>  </xamarin-android> `@(AndroidDependency)` could be equivalent to: <ItemGroup> <AndroidDependency Include="build-tools/27.0.3"> <Version>27.0.3</Version> </AndroidDependency> <AndroidDependency Include="platform-tools"> <Version>$(AndroidSdkPlatformToolsVersion)</Version> </AndroidDependency> <AndroidDependency Include="platforms/android-27"> <Version>27</Version> </AndroidDependency> <AndroidDependency Include="tools"> <Version>$(AndroidSdkToolsVersion)</Version> </AndroidDependency> </ItemGroup> [manifest]: https://gist.github.com/dellis1972/08ba76cc19cdce3dec89c68684664299 [spec]: https://microsoft-my.sharepoint.com/:w:/r/personal/mhutch_microsoft_com/_layouts/15/WopiFrame.aspx?sourcedoc=%7B0436dd38-c9ff-4cf2-b33c-ee4515b68546%7D&action=edit&wdPid=64869a58 commit e489aae Author: Jonathan Pryor <jonpryor@vt.edu> Date: Wed Feb 21 10:41:32 2018 -0500 Bump to mono/2017-12/de4729fa (#1325) Context: #1078 Context: mono/mono#7145 The primary impetus is that mono/de4729fa contains "ignore" improvements to `mono-api-html`, which will be needed in order to complete PR #1078. commit f7b24f7 Author: Dean Ellis <dellis1972@googlemail.com> Date: Tue Feb 20 16:25:23 2018 +0000 [Xamarin.Android.Build.Tests] Add tests for <ResolveSdks/> (#1321) This commit adds a basic unit test for the `<ResolveSdks/>` task. commit d207275 Author: Atsushi Eno <atsushieno@gmail.com> Date: Tue Feb 20 00:37:10 2018 +0900 [msbuild] Fix <Import>-ed filename, for case sensitivity.

Instead, it took nearly 7h, because the bundle wasn't being used, causing the mono runtimes to be rebuilt: [xa-01be]: https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android/874/ Target _BuildUnlessCached needs to be built as output file '…/xamarin-android//bin/Debug/lib/xamarin.android//../../bcl-tests/System.Runtime.CompilerServices.Unsafe.pdb' does not exist. Indeed, `System.Runtime.CompilerServices.Usafe.pdb` *doesn't* exist, nor should it, as it's compiled from IL directly. Fix mono bundle usage by updating `@(_BclTestAssemblyDestination)` to exclude `System.Runtime.CompilerServices.Unsafe.pdb`. This allows the `_BuildUnlessCached` target to properly recognize that all required files *do* exist, thus skipping the mono-runtimes build (as desired). commit 01be8ac Author: Dean Ellis <dellis1972@googlemail.com> Date: Thu Feb 15 02:38:56 2018 +0000 [Xamarin.Android.Build.Tasks] Stop designtime designer being deleted. (#1307) Fixes: #1286 We have a number of problems with our DesignTime build system. The main one which this PR addresses is the designer file is deleted by `IncrementalClean` AND `CoreClean`. This them completely messes up the DesignTime system since it can no longer find the file. So what we should be doing is making sure we don't tell the build system about the designer file ;-). We do this by not writing the path to the `$(CleanFile)`. ~~ Some background on the [DesignTime build system][2] ~~ The primary entry point is the `CoreCompile` target, with occasional calls to the `RefreshReferences` target. In theory [`$(DesignTimeBuild)`][1] should be set to `true`; however, this is not always the case which is why we have the `_SetupForDesignTimeBuild` target which hooks into the `CoreCompile` target. Additionally, `$(BuildingProject)` should be False. ([Additional information][2]). However this document is not seem to be 100% accurate since the IDE's (namely Visual Studio) do not always set the required properties. One of the key requirements for design time builds seems to be that they are independent of the main builds. The files it uses should not be removed since the `CoreCompile` target does not seem to be called consistently. For example, if the designer file is removed and the `RefreshReferences` target is called, the design time build may well fail because the targets required to re-generate the designer file are not called. Now for the problem: the `IncrementalClean` target runs between builds. It seems to want to remove files from the previous build. I suspect the purpose is to remove files that are no longer needed. (For example an assembly which is no longer referenced.) The problem is that we have a file (the design time `Resource.designer.cs`) which is not built as part of the normal build. But this file was still being written to `$(CleanFile)` which is the driver for the `IncrementalClean` process. As a result, the file gets removed because its not in the list of current `@(FileWrites)`. Not writing the name of this file to `$(CleanFile)` seems to hide it from `IncrementalClean`. There was also another problem with the `CoreClean` target. This was also removing the designer files. Again this was down to the fact that the file was listed in `$(CleanFile)`. However our older workarounds did not work since they relied on `IncrementalClean` running. For a `Clean` target invocation it does not. Again the solution seems to be Don't Write the file to `$(CleanFile)`, which is counterintuitive since we are told to write all files we generate to that file.

As a result if called directly it will generate a `NullReferenceException` as `MonoAndroidHelper.SupportedVersions` will be `null`. The `GetAndroidDependencies` should thus depend upon the `_SetLatestTargetFrameworkVersion` target. This will initialize `MonoAndroidHelper.SupportedVersions`, and will also resolve the correct `$(TargetFrameworkVersion)` if the user has `$(AndroidUseLatestPlatformSdk)`=True. commit 0dee27d Author: Jonathan Pryor <jonpryor@vt.edu> Date: Wed Feb 14 05:50:23 2018 -0500 [Xamarin.Android.Build.Tasks] Fragments & Shorter acw-map (#1301) Fixes: #1296 Xamarin.Android attempts to expose the Java-based Android API as a ".NET feeling" API. This takes many forms, such as prefixing interface names with `I`, mapping `get` and `set` methods to properties, mapping listener interfaces to events, and PascalCasing method names. This also affects Java package names and C# namespaces. When creating the `.apk` file, we philosophically need to go the opposite direction: PascalCased members need to be mapped to "something appropriate" within Java. For example, many Android Resource ids *must* be all lowercase, and Android doesn't support package names starting with an uppercase letter in all circumstances. At one point, we tried mapping C# PascalCased namespaces to camelCased namespaces, so e.g. `MyExampleNamespace` became the `myExampleNamesapce` Java package within Java Callable Wrappers. This turned out to be a Terrible Mistake, particularly on case-sensitive filesystems, as if casing was *inconsistent* (`MyExampleNamespace` vs `MyExamplenamespace`), files might not be packaged. By Mono for Android 1.0, we settled on just lowercasing the namespace name to produce Java package names within Android Callable Wrappers. This was not without it's own problems; in particular, the assembly name wasn't involved, so if the "same" type (namespace + type) were present in two different assemblies and we needed to generate Android Callable Wrappers, they'd "collide," the build would fail, and we'd have some unhappy customers. This was later addressed in Xamarin.Android 5.1 by changing the Java package name generation algorithm to be an MD5SUM of the assembly name and namespace name, thus allowing types to have assembly identity. (This was not without its own problems.) Then it gets slightly more complicated: Android allows type names to appear in various locations, such as in layout View XML. These don't allow "just" using the type name; the package name is required for types outside the `android.widget` Java package. Initially, we did nothing, so developers had to directly use the Android Callable Wrapper names: <myexamplenamespace.MyCustomCSharpView android:id="@+id/yay_csharp" .../> <fragment android:name="myexamplenamespace.MyCustomCSharpFragment" ... /> With the change in Xamarin.Android 5.1, *this couldn't work*; those types didn't exist anymore. To square this circle, we processed the resource files to "fixup" identifiers and replace them with the actual Android Callable Wrapper names. We'd replace any/all of: MyExampleNamespace.MyCustomCSharpView // Full name MyExampleNamespace.MyCustomCSharpView, MyAssembly // Partial assembly-qualified name MyExampleNamespace.MyCustomCSharpView, MyAssembly, Version=... // Full assembly qualified name myexamplenamespace.MyCustomCSharpView // compatibility name with the appropriate md5'd Android Callable Wrapper name. Brilliant as this was, there was a problem: [Bug #61073][61073]. If the assembly had a wildcard in the assembly version: [61073]: https://bugzilla.xamarin.com/show_bug.cgi?id=61073 [assembly: AssemblyVersion ("1.0.0.*")] then the "Full assembly qualified name" value would change on *every build*, which had numerious unintended knock-on effects. This was fixed in commit e5b1c92, which worked largely by just killing the Full assembly qualified name version entirely. Xamarin.Android doesn't support embedding two different versions of the same assembly, so this was considered to be fine. ...except for one compatibility case: `<fragment/>`s can contain ~arbitrary strings, and we support replacing the entire Full assembly qualified name within them: <fragment android:name="MyExampleNamespace.MyCustomCSharpFragment, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" ... /> However, in a post e5b1c92 world, the above now fails to load on the device, because it's *not* being appropriately fixed up! FATAL EXCEPTION: main Process: Mono.Samples.HelloTests, PID: 22977 java.lang.RuntimeException: Unable to start activity ComponentInfo{Mono.Samples.HelloTests/mono.samples.HelloApp}: android.view.InflateException: Binary XML file line #1: Binary XML file line #1: Error inflating class fragment ...

The problem is that what Android "sees" *should* be <fragment android:name="md5whatever.MyCustomCSharpFragment" ... /> where `md5whatever.MyCustomCSharpFragment` *is* a valid Java type that Android is able to load successfully, but because of e5b1c92 this replacement was removed. The fix: simplify the Full assembly-qualified name case to an already supported example. If the `//fragment/@android:name` value contains a `,`, assume it's an assembly qualified name and compute the Full name from it, by stripping off the comma and everything after it, then use the Full name to lookup the correct Android Callable Wrapper type. commit 5c46ee3 Author: Jonathan Pryor <jonpryor@vt.edu> Date: Wed Feb 14 05:42:22 2018 -0500 [api-xml-adjuster] Fix rebuilds (#1300) Ideally, project rebuilds when nothing has changed should be *fast*. `api-xml-adjuster` isn't: $ time (cd build-tools/api-xml-adjuster ; xbuild) real 2m1.084s user 1m55.916s sys 0m8.853s # and the rebuild! $ time (cd build-tools/api-xml-adjuster ; xbuild) real 2m0.824s user 1m56.140s sys 0m8.600s A *minimum* two minute+ rebuild -- when *nothing* has changed -- is a surefire way to get really annoyed. With diagnostic logging, we start to see the culprit: Target _ClassParse needs to be built as input file '@(ApiFileDefinition -> /Volumes/Seagate4TB/work/xamarin-android/build-tools/api-xml-adjuster/../../src/Mono.Android/Profiles/api-27.params.txt)' does not exist. This in turn causes `class-parse.exe` and `api-xml-adjuster.exe` to be *re-executed* on *every* `android.jar` on *every* build. Fix this by correcting the `//Target/@Inputs` and `//Target/@Outputs` for the `_ClassParse` and `_AdjustApiXml` tasks.

The problem with commit c4e8165 is that it overrode the `$(InstallDependsOnTargets)` property to call the `_GrantPermissions` target, which doesn't properly use `$(AdbTarget)`; it instead *requires* using the `-s` option, which is inconsistent: adb -s $(AdbTarget) shell pm grant ...

Its purpose is to examine the various settings in the project and report which Android SDK build-tools, platform-tools, etc. are required. `GetAndroidDependencies` will output an `@(AndroidDependency)` with `%(AndroidDependency.Version)` metadata. `@(AndroidDependency)` will contain `%(Identity)` values of: * `build-tools;{VERSION}`, where `{VERSION}` and `%(Version)` is controlled by the `$(AndroidSdkBuildToolsVersion)` property. * `ndk-bundle`: `%(Version)` is controlled by the `$(AndroidNdkVersion)` property. * `platform-tools`: `%(Version)` is controlled by the `$(AndroidSdkPlatformToolsVersion)` property. * `platforms;android-{API}`, where `{API}` and `%(Version)` is the API level for the `$(TargetFrameworkVersion)` in the `.csproj`.

The value for `AdjustJavacVersionArguments.JdkVersion` comes from the `<ResolveSdks/>` task `JdkVersion` output parameter, which itself comes from parsing `javac -version` output. The problem is that the regex we used to parse the output of `javac -version` wasn't properly parsing the output on Ubuntu: openjdk version "1.8.0_03-Ubuntu" Specifically, the `-Ubuntu` text was causing the regex to not match. Update the regex to be a bit more lenient, enabling it to work with the Ubuntu `javac -version` output, which *should* allow the build to progress further. commit 0114586 Author: Jonathan Peppers <jonathan.peppers@gmail.com> Date: Sun Feb 11 12:53:52 2018 -0600 [build] fix api-xml-adjuster.targets on Windows (#1291) Since 7d705bf, the Windows builds on VSTS have seemed to be failing. I tested this locally, and noticed the use of command line arguments such as: -parameter-names='%(SomeVariable)' Unfortunately, this isn't working on Windows due to the single quote. It is more appropriately expressed as: -parameter-names="%(SomeVariable)" This isn't very pretty, but it should work on all platforms. I also fixed all the tabs I saw in this file--in favor of spaces, and fixed other XML code conventions. I will now return to my regularly scheduled baby duty.

Context: dotnet/android#1078 xamarin-android uses `mono-api-html` and `mono-api-info` in order to perform API comparisons; see e.g. 4e45904. A recent problem has arisen regarding "inter-API-level diffs": there are many API changes which we consider to be acceptable, and thus would like to ignore. Unfortunately, `mono-api-html` doesn't support ignoring many of these constructs, e.g. base class changes: <h3>Type Changed: Android.Preferences.CheckBoxPreference</h3> Modified base type: <span class='removed removed-inline removed-breaking-inline'>Android.Preferences.Preference</span> <span class='added '>Android.Preferences.TwoStatePreference</span> and property type changes: <h3>Type Changed: Android.Views.InputEvent</h3> <p>Modified properties:</p> <pre> <div data-is-breaking> public <span class='added added-breaking-inline'>abstract</span> int DeviceId { get; } </div><div data-is-breaking> public <span class='added added-breaking-inline'>abstract</span> InputSourceType Source { get; } Overhaul the `mono-api-html` "ignore" infrastructure: * Introduce ignore "scoping". Previously, the ignore options would only match the *member* text against any provided regular expression. Thus, `mono-api-html -r ToString` would ignore *all* members containing `ToString`. Furthermore, there was no way to restrict the ignore to a particular type. Expand the regex semantics so that the declaring type is used as a "prefix" for the to-be-matched text. For example, if a class `Example` is removed, `mono-api-html` will now match the following value against any `-r` regular expressions: Example: Removed type * Add a `mono-api-html -v` option, to control output verbosity. When specified, `mono-api-html` will print out available `-r`/etc. option values: $ mono-api-html expected.xml new.xml -v Possible -a value: Android.Resource: Added fields: public static const int AccessibilityEventTypes; Possible -r value: Android.Preferences.CheckBoxPreference: Modified base type: 'Android.Preferences.Preference' to 'Android.Preferences.TwoStatePreference' Possible -r value: Android.Views.InputEvent: Modified properties: public int DeviceId { get; } Possible -n value: Android.Views.UnavailableException: Added type ... Additionally, allow `mono-api-html` to take a `Mono.Options.ResponseFileSource`, which allows `@response-files` to be used as command-line options.

Context: dotnet/android#1089 What is the purpose of the xamarin-android-api-compatibility repo? To ensure that we don't accidentally break API, both for the latest supported API level, and *between* API level binding assemblies. How's that working out for us? It could be better. Commit e353872 was due to a discovery that `mono-api-html` behavior had changed: it *used* to emit separate "Removed" and "Added" declarations whenever a method was changed. Then it started emitting "Modified" sections, but we weren't aware of this change. The result was an [accidental API break][pr-771], and a change to start looking for `data-is-breaking` instead of `>Removed`. [pr-771]: dotnet/android#771 (comment) *Then* we learned that `make check-inter-api-level` was broken, due to bad `test` logic. This was fixed in 6dfba92. The problem is that xamarin-android has not been able to use [xamarin-android-api-compatibility/master][pr-1078] since 6dfba92 has been merged, because it found [inter-API level breakage][inter-break] that we haven't been able to work around, e.g.: [pr-1078]: dotnet/android#1078 [inter-break]: dotnet/android#1078 (comment) <h3>Type Changed: Android.Preferences.CheckBoxPreference</h3> Modified base type: <span class='removed removed-inline removed-breaking-inline'>Android.Preferences.Preference</span> <span class='added '>Android.Preferences.TwoStatePreference</span> The "obvious" solution would have been to use the existing `inter-api-extra*` files/mechanism to ignore the changes which kept `make check-inter-api-level` from succeeding, but `mono-api-html` didn't provide a mechanism to ignore all of those changes. Doh! The fix? [Improve `mono-api-html` so it can ignore more][api-ignore] API artifacts. (Additionally, improve `mono-api-html` so that we can "scope" what changes we're ignoring, so that e.g. `mono-api-html -r` can specify the *type* that the ignore should apply to, and not be matched against *every member in the assembly*.) [api-ignore]: mono/mono@de4729f With that infrastructural change in place, update the `inter-api-extra*` files so that the acceptable changes are ignored, thus allowing `make check` to run w/o error on xamarin-android/master. Additionally: * The updated `mono-api-html` supports response files. Update the `mono-api-html` invocation to provide the `inter-api-extra*` files as response files, instead of `cat`ing the `inter-api-extra*` files. Eventually, `mono-api-html` may support comments in response files, which would allow us to use them. * Update `reference/Mono.Android.xml` for `ChoiceMode`. Commit 6874e3f updated `Android.Widget.ListView` to use `ChoiceMode` instead of `int` for many of the constants. This was inadvertently "reverted"/overwrritten in bb8630a. * Add support for a new `$(HTML_OUTPUT_DIR)` make variable. If set, `mono-api-html`-generated HTML files will be written into the `$(HTML_OUTPUT_DIR)` directory.
