Start by reproducing the OOM with repeated MainActivity background/foreground transitions and song changes, then inspect the MediaCodec calls shown in the stack trace. Confirm that repeated switching no longer causes unbounded memory growth or an OutOfMemoryError, and verify playback remains functional afterward.
