LeakCanary's launcher icon and drawables ship at xxhdpi/xxxhdpi resolutions the debug-only "Leaks" activity doesn't need. Override those two density buckets with hdpi-sized copies via debug-only resource shadowing, cutting ~35KB of redundant pixels from the debug APK. Co-Authored-By: Claude Sonnet 5 <[email protected]>
