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:

Answer 1

You've got 2 problems here.

1) Warning:Ignoring InnerClasses attribute for an anonymous inner class ......

It's just a warning. If your code works properly you can ignore it by disabling Lint in the .gradle file:

android {
    ...
    lintOptions {
        abortOnError false
    }
}

2) translation error: attempt to set or access a value of type int using a local variable of type android.support.design.widget.CoordinatorLayout$LayoutParams

This looks like in some place ProGuard optimizes variable allocation, but does it incorrectly.

Try to disable this optimization by adding the line below in your ProGuard file:

-optimizations !code/allocation/variable
