flush引发的anr问题

4.2.100

【平台信息】

Android 原生

【预期的表现】

加载pag后，能正常显示第一帧画面

【实际的情况】

引发了线上个别用户ANR
0 ANR_EXCEPTION: 1 org.libpag.PAGPlayer.flushAndFenceSync(Native Method) 2 org.libpag.PAGPlayer.flush(Unknown Source:1) 3 org.libpag.PAGView.flush(SourceFile:4) 4 cn.kuwo.ui.nowplay.widget.KwPAGView.flush(SourceFile:4)

测试发现，flush回调回触发2次

【Demo及附件】

线上问题引发代码：
pagFile.replaceImage(replaceIndex, PAGImage.FromBitmap(squareBitmap)) mPagView.composition = pagFile mPagView.progress = 0.1 mPagView.setRepeatCount(0) mPagView.setScaleMode(PAGScaleMode.Zoom) mPagView.flush()

后以为是调用progress和flush造成两次flush的冲突anr，改代码如下：
if(rid == mLastRid){ LogMgr.d("setCoverBitmap","SquareCoverShadowDelegate setCoverBitmap rid:$rid isSameRid") return } mLastRid = rid pagFile?.replaceImage(replaceIndex, PAGImage.FromBitmap(squareBitmap)) mPagView.composition = pagFile LogMgr.d("setCoverBitmap","SquareCoverShadowDelegate setCoverBitmap rid:$rid success ${mPagView}")

测试发现，flush和animtionupdate回调，还是会触发2次。
