NoClassDefFoundError: android.support.v7.internal.view.menu.MenuBuilder

by

EDIT:

The solution that worked for me was (Using Proguard) to replace this:

-keep class android.support.v4.** { *; } 
-keep interface android.support.v4.** { *; }

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

with this:

# Allow obfuscation of android.support.v7.internal.view.menu.**
# to avoid problem on Samsung 4.2.2 devices with appcompat v21
# see https://code.google.com/p/android/issues/detail?id=78377
-keep class !android.support.v7.internal.view.menu.**,android.support.** {*;}

Credit goes to the google group, #138.

Old answer (Temporary Workaround):
It happens in a project where I use an spinner in the ActionBar. My solution was to check for those conditions and change the app flow:

public static boolean isSamsung_4_2_2() {
    String deviceMan = Build.MANUFACTURER;
    String deviceRel = Build.VERSION.RELEASE;
    return "samsung".equalsIgnoreCase(deviceMan) && deviceRel.startsWith("4.2.2");
}

Then in the activity’s onCreate method:

if (isSamsung_4_2_2()) {
    setContentView(R.layout.activity_main_no_toolbar);
} else {
    setContentView(R.layout.activity_main);
}

As pointed out this is not a definitive solution, it is just a way to allow users to have access to limited functionality while a more permanent solution is found.
