i not tested but in wrapped library as class this problem occured

[lakeinchina]

it looks like system call textureview.onSurfaceTextureDestroyed() after activity.onDestroy(). it appears on android7.1.1beta. are you testing it in 7.1.1?

[sahandmax]

My Testing OS is Android 6.0 but problem still available

This bug is still available in my test demo app with android api version 18 I'am getting this error log

I try to fixed this issue by check null but i don't know that make any effect? /** * * @param releaseTexture true if you won`t reuse this surfaceTexture later */ public void stopPreview(boolean releaseTexture) { if(videoClient != null) { videoClient.stopPreview(releaseTexture); LogTools.d("RESClient,stopPreview()"); } }

Have any idea?

[lakeinchina]

that is weird.In some case, onSurfaceTextureDestroyed was called after OnDestroy and I don`t know why.
