fix(android): resolve black screen and improve reliability#5
Conversation
Replace Thread.sleep(1000) on UI thread with Handler.postDelayed to prevent ANR and rendering failures. Fix _isUnityReady flag being set when player creation fails. Fix broken setZ reflection (missing float parameter) that prevented background Z-ordering. Add null-safety for requestFrame() results. Fix pauseUnity ignoring the pause parameter. Replace silent catch blocks with Log statements for debuggability. Remove hardcoded Google Maps API key from example app. Closes #3 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

What
Fix multiple Android-side bugs that cause black screen and silent failures in Unity player initialization.
Why
Issue #3 reports a black screen. Root cause analysis found 6 interacting bugs:
Thread.sleep(1000)on UI thread blocks rendering and risks ANR_isUnityReadyset totrueeven when UPlayer creation throws —isUnityReady()returns true butgetPlayer()returns nullUPlayer.setZ()uses broken reflection (getMethod("setZ")withoutfloat.classparam) — the Z-index call to push background Unity view behind React content always silently failsrequestFrame()can return null but callers never check — NPE crash or silent failurepauseUnity(view, pause)ignores thepauseboolean and always pausesHow
Thread.sleep(1000)withHandler.postDelayed()— same 1s delay but non-blocking_isUnityReadyonly set on successsetZ()to callframe.setZ()directly instead of broken reflectionrequestFrame()in bothaddUnityViewToBackgroundandaddUnityViewToGrouppauseUnityto respect the boolean parameter (pause vs resume)Log.e/Log.wfor debuggabilityHandler()constructor →Handler(Looper.getMainLooper())Testing
No test suite exists for native code. Changes are mechanical (null guards, logging, correct API usage) and don't alter the initialization sequence — only fix silent failures within it. Manual testing on Android device with Unity project recommended.
