Question

이 프로젝트는 다른 사람의 얼굴에 포인트를보고 비디오를 재생해야합니다. 나는 3 개의 지역으로 스크린을 나누고 지명했다. 프로젝트 카메라를 돌릴 때 갑자기 제 2 영역을 보게되고 제 2 영역에는 아무런 조치가 없기 때문에 오류가 없습니다. 그러나 카메라가 첫 번째 또는 세 번째 영역을 볼 때 - 프로젝트는이 영역에서 비디오 재생을 시작해야합니다 - 갑자기 프로젝트가 닫힙니다.

그리고이 생각은 문제가 :

당신이 관련된 모든 방법을 실행 startPlaying() 오류의 근원이라고 생각하면

private void startPlaying(boolean startFromCurrent) { //IHTIYAC 1 

     videoView.stopPlayback(); 
     videoView.setVideoURI(uri1); 
     //videoView.requestFocus(); 

... 
      } 
    }); 

    } 

Answer 1

내부의 Android 조회수는 runOnUiThread() :

private void startPlaying(boolean startFromCurrent) { 
    runOnUiThread(new Runnable(){ 
     @Override 
     public void run(){ 
      videoView.stopPlayback(); 
      videoView.setVideoURI(uri1); 
     } 
    }); 
...
