Trying to reproduce this on my 4.2.2 (v17) Nexus 4. Added this drawable:
<transition xmlns:android="http://schemas.android.com/apk/res/android " >
<item android:drawable="@drawable/test_drawable_blue"/>
<item android:drawable="@drawable/test_drawable_green"/>
</transition>
where blue/green drawables look like this:
<shape
xmlns:android="http://schemas.android.com/apk/res/android "
android:shape="rectangle">
<size
android:width="@dimen/drawable_large_size"
android:height="@dimen/drawable_small_size" />
<solid
android:color="@color/test_blue" />
</shape>
Then added this test:
@Test
public void testMutateTransitionDrawable() {
Drawable drawable = ResourcesCompat.getDrawable(mResources,
R.drawable.test_transition_drawable, null);
assertTrue(drawable instanceof TransitionDrawable);
Drawable mutated = drawable.mutate();
assertTrue(drawable instanceof TransitionDrawable);
assertTrue(mutated instanceof TransitionDrawable);
}
It passes on the device. Going to also try on other earlier devices a bit later in the day once they are charged.

Description
java.lang.IllegalArgumentException: attempt to remove OnFrameMetricsAvailableListener that was never added

To repro, run the app, then tap the home button. This disables jank stats tracking, which ends up removing a delegate listener and then the delegator itself (apparently twice).
It's not 100%, but it's fairly frequent.
Looks like there are two places in JankStatsApi24Impl where we remove the delegator listener from the window, in removeFrameMetricsListenerDelegate() (when we have removed the last delegate) and in OnFrameMetricsAvailable (when we detect a delegates list size of 0)
