我測試了一個播放視頻的Android應用程序。 問題是視頻播放失敗，未知錯誤：Android Media Player發送一個神祕的請求
MediaPlayer(20533): Error (1,-2147483648)
應用代碼：
// Place the video view.
mVideoView = (VideoView) findViewById(R.id.surface_view);
// Retrieve the video path.
path = getIntent().getStringExtra(PATH);
Log.i(TAG, "Play the file : " + path);
// Set the video to play.
mVideoView.setVideoPath(path);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
// Start the video play.
mVideoView.start();
走秀視頻的Web服務器是一個PHP 5的Apache2
