Can you please provide the diagnostic build log? Also, in the It looks like we’re not properly translating <fragment android:name="Mono.Samples.Hello.MyFragment, Hello, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" android:id="@id/csharp_full_assembly" android:layout_width="fill_parent" android:layout_height="wrap_content" />This is wrong; it should match one of the previous (in the same file!) lines, e.g.: <fragment android:name="md5c7537e80324c78ebad79edc8b8a9cda5.MyFragment" android:id="@id/csharp_full_assembly" android:layout_width="fill_parent" android:layout_height="wrap_content" />…but why wouldn’t that be happening? That seems quite odd. :-/ It's plausible that this is fallout from commit e5b1c92 -- last December! -- which wasn't not part of d15-6 (deliberately!). If this is the case, then ~any Xamarin.Android build after 2017-Jan-11 should likewise exhibit this bug, meaning it is not due to the mono/2017-12 bump. |

@jonpryor I was unable to reproduce this issue earlier today using monodroid/master/de602598, which is why I was curious as to the delta between master and mono-2017-12.

I think my inability to reproduce yesterday against master may have been due to an accidental usage of a different version which existed in a side by side installation. I am able to reproduce this against master as well. |

Fixes: dotnet#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.

While trying to repro Issue dotnet#1296, I had a brilliant idea: let's use the new CodeBehind support from 7c31899! Everything then fell apart. For starters, Issue dotnet#1296 deals with Fragments, and 7c31899 didn't support the presence of `<fragment/>` within Layout files. Plumb support for that, by adding: partial class MainActivity { partial void OnLayoutFragmentNotFound<T> (int resourceId, ref T type) where T : global::Android.App.Fragment; } Another issue was noticed as well: all the line numbers in the `#line` pragmas were always `1`. This was narrowed down to a bug in `GetLineInfo()`. Then there's an issue with where I was using the CodeBehind file: within the `src/Mono.Android/Test` project, which is in the `Xamarin.Android.RuntimeTests` namespace. This prompted all manner of namespace resolution failures: error CS0234: The type or namespace name 'App' does not exist in the namespace 'Xamarin.Android' (are you missing an assembly reference?) ... Fix this by using `CodeTypeReferenceOptions.GlobalReference` as much as is practical (which isn't enough), and by "kludging" up the `CodeNamespaceImport` construction so that we instead emit: using global::System; Finally, the generated codebehind had some weird nesting going on: partial class MainActivity { public __first_text_view_Views first_text_view {get;} public sealed partial class __first_text_view_Views { public __second_text_view_Views second_text_view {get;} public sealed partial class __second_text_view_Views { public sealed partial class __csharp_simple_fragment_Views { public sealed partial class __csharp_partial_assembly_Views { } } } } } It was bizarre *and* unusable: the `second_text_view` property -- corresponding to `<TextView android:id="@+id/second_text_view" />` -- was *nested within* a generated `MainActivity.__first_text_view_Views` type, and I'm not sure why that existed. Furthermore, it *can't* work, as the generated `MainActivity.__first_text_view_Views.__CreateClass___second_text_view_Views()` method depends on a constructor which doesn't exist: private @__second_text_view_Views @__CreateClass___second_text_view_Views() { // There *is* a __second_text_view_Views(Activity) constructor, // but not __second_text_view_Views(__first_text_view_Views). return new @__second_text_view_Views(this); } I "solved" (?) this by updating `LoadWidgets()` so that it always used `widgetRoot` for all recursive calls to `LoadWidgets()`, so that there is only ever one root. This removed all the nested types.

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.

For example, the [first commit after the mono bump][xa-01be] *should* have taken around 3h to build. 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 ...

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.
