Android application which monitors Bitcoin, cryptocurrencies, cryptoassets and derivatives, triggering alarms according to user settings.

hit alarm creation alarm list hit alarm firing

Supports 2 alarm types:

  • Price Hit - Triggered when price crosses the alarm's upper or lower limit. One limit may be left empty to create an alarm with a single trigger.
  • Price Change - Triggered when price changes more than X amount (in currency or percentage) in a specified time frame (e.g. 15 min). It uses a rolling time frame: price is fetched with a given update interval (e.g. 30 s) and compared with the price fetched one time frame ago (e.g. 15 min ago).

Sound and vibration are configurable globally, and individually for each alarm. Lists of exchanges, pairs and alarms are fully searchable, allowing quick setup and configuration. The alarm list behaves as your ticker, where you can reorder your alarms and directly change their limits. Alarms can also be set to snooze automatically on price retrace. Triggered alarms ring, displaying their status, until you turn them off. Just like an alarm clock.

Market data is retrieved directly from the exchanges via Wi-Fi or Mobile Data (if allowed). libdynticker is used to interface with the exchanges. Thus, Boilr supports all exchanges available on libdynticker, as all their pairs.

To create alarms Boilr uses libpricealarm.

Other libraries we use: changeloglib and UndoBar.

Check Boilr's website to see it in action: http://boilr.mobi Website source-code is available at boilr-site.

Getting help

Bug reports, feature requests and general help questions should be submitted on Boilr's GitHub issues. Try being specific when choosing the right title and label for your issue.

You can browse through a FAQ by checking all issues labeled as questions.

Troubleshooting

Trouble Solution
Alarm not updating when phone is sleeping. Set Settings > Wi-Fi > Advanced > Keep Wi-Fi on during sleep to Always

Reasons for permissions

Permission Reason
Read the contents of your SD card Used to fetch your custom ringtones.
Disable your screen lock So you can turn off a ringing alarm without unlocking your device.
Full network access To fetch data from the exchanges.
View network connections To know whether you're using Wi-Fi or Mobile Data, allowing Mobile Data restriction.
Run at startup To grab your active alarms and start updating them.
Control vibration Allows vibration when an alarm is triggered.
Prevent phone from sleeping Used to keep showing the alarm triggered activity until you press the turn off button.

If you would like to add more exchanges to Boilr check libdynticker's contributing guide.

Building

  1. Fill out the prerequisites for Android Maven Plugin.
  2. Install Android API 26 SDK and Android Support Repository.
  3. mvn install:install-file -DgroupId=android -DartifactId=android -Dversion=8.0.0 -Dpackaging=jar -Dfile=$ANDROID_HOME/platforms/android-26/android.jar
  4. mvn install:install-file install:install-file -Dfile=$ANDROID_HOME/extras/android/m2repository/com/android/support/support-annotations/22.1.1/support-annotations-22.1.1.jar -DpomFile=$ANDROID_HOME/extras/android/m2repository/com/android/support/support-annotations/22.1.1/support-annotations-22.1.1.pom

For now on you can use:

  • mvn package -P debug to build an apk in debug mode.
  • mvn package -P release to build an apk in release mode, which will be optimized, signed and aligned.
  • mvn android:deploy to install the generated apk in any connected phones or emulators.

Note: mvn package with no profile associated builds an unsigned release mode apk, unsuitable for deploy. It is meant for further processing by downstream projects like F-Droid.

Debuging

adb logcat "ActivityManager:I AndroidRuntime:E Boilr:D *:S" runs logcat with a nice filter to debug Boilr.

Importing into Eclipse

If you are no vi or emacs ninja you can use Eclipse to ease your work in Boilr.

  1. Install and configure the ADT plugin.
  2. Install m2e-android. (Eclipse Mars already ships with Maven.)
  3. Clone changeloglib.
    3.1 Checkout tag v.1.5.2 with git checkout v.1.5.2.
    3.2 Go to File->Import->Existing Android Code Into Workspace, import just what's in the ChangeLogLibrary directory and name the new project as ChangeLogLibrary.
    3.3 In the project's Java Build Path remove source folder src and add java.
  4. Clone UndoBar.
    4.1 git checkout fcb99913808ee47a3803d3f800cbee6b7678ba21
    4.2 Go to File->Import->Existing Android Code Into Workspace, import just what's in the library directory and name the new project as UndoBar.
    4.3 Right click in the project, go to Android Tools and run Add Support Library...
  5. Go to File->Import->Existing Projects into Workspace and select Boilr's git root directory.

Use Eclipse only for writing code. Always compile in the shell using Maven.

Note: we do plan to migrate to a Gradle build system and Android Studio IDE in the near future.
