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.

The only remaining usages of androidx.core.os.CancellationSignal in Fragment are baked into the public API between the Fragment and Transition library that cannot be removed without breaking binary compatibility between those modules.
Since we'll need to keep those APIs in place ~forever, we've removed everything possible.
Description
AndroidX has increased the global
minSdkto 19, which means the Fragment library can useandroid.os.CancellationSignalinstead ofandroidx.core.os.CancellationSignal.This might be difficult, though, because there is an internal API surface shared between Fragment and Transition library that uses the compat class.
