Proguard issue "Warning:Ignoring InnerClasses attribute for an anonymous inner class"

Question

I don't know how I can describe this issue. I searched a lot, but I didn't find any solution.

Also this solution did not help me -keepattributes EnclosingMethod:

dependencies {
    compile project(':libraries:material-drawer')
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.android.support:recyclerview-v7:23.2.0'
    compile 'com.android.support:design:23.2.0'
    compile 'com.google.code.gson:gson:2.4'
    compile 'com.mcxiaoke.volley:library:1.0.19'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.squareup.okhttp:okhttp:2.4.0'
    compile 'de.greenrobot:eventbus:2.4.0'
    compile 'com.commit451:PhotoView:1.2.4'
    compile 'com.nineoldandroids:library:2.4.0'
    compile 'com.viewpagerindicator:viewpagerindicator:2.4.3'
    compile('com.github.afollestad.material-dialogs:commons:0.8.5.6@aar') {
        transitive = true
    }
    compile('com.crashlytics.sdk.android:crashlytics:2.5.5@aar') {
        transitive = true;
    }
}

And the jar folder contains ormlite-android-4.48.jar and ormlite-core-4.48.jar.

Proguard File:

Answer 1

Try adding

-keepattributes InnerClasses
-dontoptimize

to the ProGuard config. That should fix the problem.

It's probable that incompatible optimizations are applied (that probably causes the last line of the error log).

If you want to allow optimizations, it's necessary to fine tune optimizations config with

-optimizations optimization_filter 

option in ProGuard config.

Answer 2

Adding these lines to proguard-rules.pro file fixed my issue.

-keepattributes EnclosingMethod
-keepattributes InnerClasses

Answer 3

I suggest -dontwarn InnerClasses
