Android Proguard configuration for the v7 Support Library ActionBar

Question

I'm using the v7 Support Library to show an ActionBar on Android 2.x. It works well enough but I had to fix a few class/method not found errors after enabling Proguard.

Are there any guidelines on which classes need to be preserved?

So far I have these:

-keep public class android.support.v7.internal.widget.ActionBarContainer
-keep class android.support.v7.internal.widget.ActionBarView$HomeView
-keep public class android.support.v7.internal.widget.ActionBarContextView

It seems to work now but I'm not that confident that it won't crash at some stage because of some other supposedly internal class referenced in some XML file.

Answer 1

I solved it with:

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

Answer 2

I use this, somewhat similar to what the v4 version suggested:

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

Answer 3

I got it from Android Proguard Snippet

-keep public class android.support.v7.widget.** { *; }
-keep public class android.support.v7.internal.widget.** { *; }
-keep public class android.support.v7.internal.view.menu.** { *; }

-keep public class * extends android.support.v4.view.ActionProvider {
    public <init>(android.content.Context);
}

Hope it will work.
