Ok, this is a little disappointing, and I was looking for Stack, but none of the answers help.
I have an Android app that cycles through various content on the screen. At one point, it plays a video, the same video downloaded from the same place.
After a random number of plays, he decides to stop playing the video file and throws an error above (-2147483648), which is a common error of the file not found / irregular in shape.
The problem is that the video plays correctly many times before this error occurs. I tried a number of alternatives to fix this:
- VideoView playing a file (start)
- The combined reading of MediaPlayer + SurfaceView from a file
- Reading MediaPlayer + SurfaceView from a file descriptor
- forcing read permissions in the world
- copying the file to a temporary file and playing it back
- manually release the media player for the VideoView and MediaPlayer parameters
- start manual garbage collection after each game
and yet, after several games, in the end, he will refuse to play the video.
One change, which may or may not be relevant, is to play in a file descriptor that creates a meta player to prepare the Java I / O Exception, which I think is related, there may be some lock in the file.
The only way to fix this is to reboot the device. Restarting the application does not fix it, and it immediately refuses to play the file.
Here is the VideoView playback code:
// from main activity File afile = new File(btvapp.fileroot,btvapp.getDailyVideo().get("FILENAME")); afile.setReadable(true, false); theVideo = (VideoView) findViewById(R.id.videoViewer); theVideo.requestFocus(); theVideo.setVideoPath(afile.getPath()); theVideo.setOnPreparedListener(this); theVideo.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { @Override public void onCompletion(MediaPlayer mp) { // TODO Auto-generated method stub //mp.release(); theVideo.stopPlayback(); mp.release(); finish(); } } ); theVideo.setOnErrorListener(new MediaPlayer.OnErrorListener() { @Override public boolean onError(MediaPlayer mp, int what, int extra) { finish(); return false; } }); // play on prepared function @Override public void onPrepared(MediaPlayer mp) { // TODO Auto-generated method stub mp.start(); }
The surface view uses the example of the Android SDK media player almost exactly, but I don’t think it's worth pasting the code, because the error occurs regardless of whether you use the mediaplayer + surfaceview method or the VideoView playback method.
Thoughts? Driving me crazy.
UPDATE . Here's the full log, including the main application and generated video activity

UPDATE 2: I tested the code on two other Android devices (one ICS, one Gingerbread) and it is annoying that it works fine on them and works for more than 12 hours without incident. Thus, it looks like a platform error, but you still need to solve this problem.
