我正在尝试在我的应用程序中播放视频，但是出现了无法播放此视频的错误。我看到很多关于此问题的讨论。他们建议在播放器准备就绪后开始播放视频。我也这样做了，但是无法找出问题所在。请查看下面的代码。
public class Video extends Activity implements MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener {
public VideoView vidPlayer;
@Override
protected void onCreate(Bundle savedInstanceState) {
setup();
activateVideoPlayer();
}
public void setup() {
setContentView(R.layout.step_video);
vidPlayer = (VideoView) findViewById(R.id.videoPlayer);
String playableUrl = "http://teststreaming7v.s3.amazonaws.com/public/7515/1374782317346-beagle_puppy_howl_640x360_448_main.mp4";
}
@Override
public void onPrepared(final MediaPlayer mediaPlayer) {
mediaPlayer.setLooping(false);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
startPlayer();
videoLoaded = true;
mediaPlayer.setOnBufferingUpdateListener(new MediaPlayer.OnBufferingUpdateListener() {
// show updated information about the buffering progress
public void onBufferingUpdate(MediaPlayer mp, int percent) {
Log.d(this.getClass().getName(), "percent: " + percent);
}
});
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mediaPlayer) {
progress.setProgress(100);
setResult(Activity.RESULT_OK);
finish();
}
});
readyToPlay = true;
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}
@Override
public void onPause() {
super.onPause();
pausePlayer();
}
@Override
public void finish() {
super.finish();
overridePendingTransition(R.anim.engagement_fade_in, R.anim.engagement_fade_out);
}
@Override
public void onBackPressed() {
isGoingBack = true;
setResult(Activity.RESULT_CANCELED);
finish();
}
@Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
JLogger.getInstance(this).log("Video Player Error!!" + Integer.toString(i) + " / " + Integer.toString(i1));
return false;
}
public void startPlayer() {
isPaused = false;
vidPlayer.start();
}
public void pausePlayer() {
isPaused = true;
vidPlayer.pause();
}
private void activateVideoPlayer() {
vidPlayer.setOnErrorListener(this);
vidPlayer.setOnPreparedListener(this);
btnPlay.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if (vidPlayer.isPlaying()) {
pausePlayer();
} else {
startPlayer();
}
}
});
vidPlayer.setVideoURI(Uri.parse(playableUrl));
vidPlayer.seekTo(step.resumePosition);
}
}
我使用的设备是摩托罗拉Atrix - Android 4.1.2 - 解锁状态。 我还在其他设备上尝试过，如Nexus 4、5和三星Tab 2。它们在那里都可以正常工作。
这是我的日志：
