MockableJarGenerator is a modified version of official MockableJarGenerator which can generate a "mockable" version android.jar (with enables internal and hidden APIs). You can find those android.jar in this project: anggrayudi/android-hidden-api
Why we need this project? Because when you use a hidden-api's android.jar, the gradle task mockableAndroidJar will throws following error.
Error:Execution failed for task ':app:mockableAndroidJar'.
> java.lang.NullPointerException (no error message)
So your unit testing may fail if you're trying to mock or depends on any android platform class. This error was throws by asm operation when generator trying to writes a modified *.class file to the output JAR file.
This modified generator fixed the issus and you can manually place the generate mockable-android-xx.jar to following directory: projectRootDir/build/generated/.
MockableJarGenerator generator = new MockableJarGenerator(false);
File input = new File("android-xx.jar");
File output = new File("mockable-android-xx.jar");
try {
generator.createMockableJar(input, output);
} catch (IOException e) {
e.printStackTrace();
}Any issues or PRs are welcome!
