Build Instructions

pipeline status

The gradle build system will fetch all dependencies and generate files you need to build the project. You first need to generate the (replace YOUR_SDK_DIR by your actual android sdk dir) file:

$ echo "sdk.dir=YOUR_SDK_DIR" >

You can now sync, build and install the project:

$ ./gradlew assembleDebug   # assemble the debug .apk
$ ./gradlew assembleRelease # assemble the release .apk (signing keys are required)
$ ./gradlew installDebug    # install the debug .apk if you have an
                            # emulator or an Android device connected

You can use Android Studio by it as existing project.

For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Butter will be maintained according to the Semantic Versioning guidelines as much as possible.

Releases will be numbered with the following format:


Constructed with the following guidelines:

  • A new major release indicates a large change where backwards compatibility is broken.
  • A new minor release indicates a normal change that maintains backwards compatibility.
  • A new patch release indicates a bugfix or small change which does not affect compatibility.
