Component used: androidx.core.core-splashscreen

Version used: 1.0.1 or 1.1.0-alpha01

Devices/Android versions reproduced on: Android 6.0 (API32) or below

Recently I found a bug related to function getDrawable, converting vector with tag gradient, and because it was implemented from API24 then getDrawable causes app crush.

1st bug is located here -> https://github.com/androidx/androidx/blob/androidx-main/core/core-splashscreen/src/main/java/androidx/core/splashscreen/SplashScreen.kt#L264

instead of:

icon = currentTheme.getDrawable(typedValue.resourceId)

and it must be replaced on:

icon = AppCompatResources.getDrawable(activity, typedValue.resourceId)

2nd bug is located here -> https://github.com/androidx/androidx/blob/androidx-main/core/core-splashscreen/src/main/java/androidx/core/splashscreen/SplashScreen.kt#L354

instead of:

val iconBackgroundDrawable = context.getDrawable(R.drawable.icon_background)

and it must be replaced on:

val iconBackgroundDrawable = AppCompatResources.getDrawable(context, R.drawable.icon_background)

Example of vector drawable from project -> https://raw.githubusercontent.com/bmx666/MidiSheetMusic-Android/844c503e9859c7e253858e298e30f2929a7b0171/app/src/main/res/drawable-v24/ic_launcher_foreground.xml

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.

Also not reproducible on Galaxy Nexus running 4.0.1 (v14), 4.0.4 (v15) and 4.2.2 (v17)

https://android-review.googlesource.com/c/platform/frameworks/support/+/960032 with the test. Closing as not reproducible. If this is still happening for you, we'd need to see either a test (same as in this CL) or a small, standalone sample project that reproduces this issue on v17 (or other) devices.

Marked as fixed.
