proguardRelease FAILED when compiling apk with assembleRelease in Android Studio

Question

I\'m trying to compile my app as assembleRelease in Android Studio 1.0.1 and get the following message:

FAILURE: Build failed with an exception.

* What went         


        

Answer 1

Add this to ProGuard setting file(like proguard-rules.pro)

-ignorewarnings 

Answer 2

Add this to ProGuard setting file(like proguard-rules.pro)

-dontwarn okio.**

Answer 3

I had the same problem with Gradle 1.1.0. It remembered some old class references which I have moved, and I couldn't build apk.

Try Build > Clean.

It helped me, and now I can build apk again.

Answer 4

I had to disable proguard with

minifyEnabled false

Not the best solution, but it works.

Answer 5

I think you have already resolve your problem. Anyway see this link: https://stackoverflow.com/a/29858070/3864698

The fix is planned for Gradle Plugin version 1.4. So we must wait a little bit.
