Research direction

Start on the start_kotlin branch by locating the android_cupcake.png drawable and its references. Reproduce the launch on an xxhdpi Android device or emulator, then verify that the app starts without the oversized-bitmap crash while retaining the image.

Written by the indexing model from the issue text.

Description

I just started the app as proposed in codelab and this happened:

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.background, PID: 24751
    java.lang.RuntimeException: Canvas: trying to draw too large(118054944bytes) bitmap.
        at android.view.DisplayListCanvas.throwIfCannotDraw(DisplayListCanvas.java:229)
        at android.view.RecordingCanvas.drawBitmap(RecordingCanvas.java:97)
        at android.graphics.drawable.BitmapDrawable.draw(BitmapDrawable.java:529)
...

Device:

Moto G 5
API Level 27

As described in this answer:

When an image that is only in drawable/folder is used on xxhdpi device, the potentially already big image is upscaled by a factor of 3, which can then in some cases cause the image's memory footprint to explode.

In the case of this project the error is happening due to the drawable android_cupcake.png
