Android - dexguard removes menu icons

Question

Hey I'm obfuscating my app using dexguard and so far everything worked fine. Now I'm trying to add icons to the action bar menu. without dexguard obfuscation the icons are shown but with it they disappear(the text is still there). I feel that is has something to do with the xml <menu> tag since the obfuscation doesn't affect other liner/relative layout.

This is my actions.xml (under res.layout, icons are under res.drawble-xxx):

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="match_parent" android:layout_width="match_parent">

    <item android:id="@+id/action_1"
          android:title="action_1"
          android:icon="@drawable/action_1_icon"
    />

    <item android:id="@+id/action_2"
          android:title="action_2"
          android:icon="@drawable/action_2_icon"
    />

    <item android:id="@+id/action_3"
          android:title="action_3"
          android:icon="@drawable/action_3_icon"
    />

</menu>

I've also tried to add them programmatically

 @Override
public boolean onPrepareOptionsMenu(Menu menu) {
    MenuItem action_1 = menu.findItem(R.id.action_1);
    action_1.setIcon(getResources().getDrawable(R.drawable.action_1_icon));

    MenuItem action_2 = menu.findItem(R.id.action_2);
    action_2.setIcon(getResources().getDrawable(R.drawable.action_2_icon));

    MenuItem action_3 = menu.findItem(R.id.action_3);
    action_3.setIcon(getResources().getDrawable(R.drawable.action_3_icon));

    return super.onPrepareOptionsMenu(menu);
}

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.layout.actions, menu);
        return super.onCreateOptionsMenu(menu);
    }

But still obfuscation removes the menu icons.

Answer 1

The solution for this issue: The Menu class (under android.view ) is using the MenuBuilder implementation (under android.support.v7.internal.view.menu ). So I've added the rule

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

and now it works.
