我的android应用显示了一个视频，并且必须一直运行，但是几个小时后我的应用停止了

Question

I'm new on android application and i'm creating an app that shows a video using a VideoView, I use a CountDownTimer to search each 15 seconds for video updates and play another video. My app works very well during 2 or 3 hours but after this my app just stop, the application doesn't close but is stopped and I must close and open again. What should I do? Thanks.

Answer 1

It literally stops on the screen, it stops the timer and video view. Here is the code that i'm using to count time to call functions to show video and time.

new CountDownTimer(20000, 1000) {
             public void onTick(long millisUntilFinished) {

                time++;
                downloadTime++;
                if(downloadTime == 2){  // Should be executed each 2 seconds
                    DoDownloads();
                    downloadTime = 0; //
                }
                    showPlayer();
                    showTime();

             }

             public void onFinish() {
                 this.start();
             }
          }.start();

I can't show any log because this happens after some hours and can be 2 hours or 10 hours, and i'm testing on tablet.

We would need the code of the rest of your functions, like DoDownloads(); showPlayer(); showTime(); DoDownloads(); showPlayer(); showTime();

anyways, i wouldnt restart the countdown that way. Id try with a handler and postdelayed(Runnable), like:

private Handler handler = new Handler();

private Runnable runnable = new Runnable() {
   @Override
   public void run() {
            time++;
            downloadTime++;
            if(downloadTime == 2){  // Should be executed each 2 seconds
                DoDownloads();
                downloadTime = 0; //
            }
                showPlayer();
                showTime();

     handler.postDelayed(this, tiempo);
   }
};

handler.postDelayed(runnable, tiempo); 

And also, you should debug the app and copy/past the log cast in the moment it fails, and give us some information about in what point the execution wsa
