Keep PixelCopy, masking, compositing, and cleanup from accessing the shared bitmap concurrently. Fixes GH-5340 Co-Authored-By: Codex <noreply@openai.com>
Re-arm the recorder's content-change gate when a capture is skipped because another frame is still in flight. This ensures the latest UI state is retried on the next capture interval. Refs GH-5340 Co-Authored-By: OpenAI Codex <noreply@openai.com>
Reduce replay screenshot memory while retaining ARGB_8888 for SurfaceView compositing. Refs GH-5340 Co-Authored-By: Codex <noreply@openai.com>

📜 Description
Use
RGB_565for replay recording bitmaps when alpha is unnecessary. PixelCopy keepsARGB_8888when SurfaceView capture is enabled because compositing depends on the transparentholes left in the Window capture. Canvas capture always uses
RGB_565because it does not supportSurfaceView compositing.
This PR depends on #5808.
💡 Motivation and Context
RGB_565halves the recording bitmap's memory footprint. The previous switch toARGB_8888wasbased on an unconfirmed theory about native bitmap crashes; #5808 instead addresses the concurrent
PixelCopy access and recycling that can produce those crashes.
Refs #5340
💚 How did you test it?
./gradlew ':sentry-android-replay:testDebugUnitTest' --tests='*PixelCopyStrategyTest*' --info./gradlew spotlessApply apiDumpAdded assertions that regular PixelCopy capture uses
RGB_565and SurfaceView capture retainsARGB_8888.📝 Checklist
