Solution 1:

This is because ProGuard is obfuscating your apk to make it harder for hackers to reverse-engineering your apk. If you think obfuscation is not needed, change this in your gradle configuration:

minifyEnabled false

Alternatively, you can let ProGuard skip obfuscation of the support libraries by using this:

minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

Add a file proguard-rules.txt and try adding these lines:

-keep class android.support.v7.internal.** { *; }-keep interface android.support.v7.internal.** { *; }-keep class android.support.v7.** { *; }-keep interface android.support.v7.** { *; }
