Build failed using ProGuard and Gradle

[burton999dev]

I'm using ProGuard v5.3.2. I resolved this issue to add the proguard settings.

-keep interface com.birbit.android.jobqueue.** { *; }

I'm not sure this solution is best. It would be great if the proguard file is officially provided.

It would be great if the proguard file is officially provided.

I'd love that as well! https://developer.android.com/studio/projects/android-library.html#Considerations mentions how you can use consumerProguardFiles to provide Proguard rules with your library.

[yigit]

yea, this should be added.

With android-priority-jobqueue 2.0.1 and Proguard v5.3.3, the build fails with this:

I fixed this by adding the following Proguard rules:

-dontwarn com.birbit.android.jobqueue.scheduling.Gcm*

[guillerodriguez]

BTW I did not need to add -keep interface com.birbit.android.jobqueue.** { *; } ; my build does not fail if I leave that out.
