我在三星S3(安卓4.1.1)上运行的视频有问题,这个问题似乎是因为videoview是一个片段,因为如果我把它放在和活动,它的工作原理。 此外,我发现,如果我打开的GPU硬件加速,视频作品。 我也有一个游戏由一个SurfaceView绘图和观点并没有很好地工作(仅适用于GPU上的)......显示在应用程序内容的其余部分,因为它应该(按钮和其他布局)。
I have a problem in running a video in Samsung S3(Android 4.1.1), the issue seems to be because the videoview is on a fragment because if I put it on and activity, it works. Also I found out that if I turn on the GPU hardware acceleration on, the video works. I have also a game made by drawing on a SurfaceView and that view doesn't work as well(only with GPU on)... The rest of the app content is displayed as it supposed to (buttons and other layouts).
我测试在Nexus S和模拟器上的应用程序,并能正常工作,还对其他设备。
I tested the app on Nexus S and on the emulator and it works fine, also on other devices..
有谁知道什么问题可能是什么? 谢谢!
Does anyone know what the problem could be? Thank you!
这里是code:
public class VideoFragment extends Fragment implements MediaPlayer.OnCompletionListener,
MediaPlayer.OnPreparedListener, MediaPlayer.OnErrorListener {
private Video mVideo;
private VideoView mVideoView;
// The video position
private int mPosition;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View fragmentView = inflater.inflate(R.layout.screen_video, container, false);
mVideoView = (VideoView) fragmentView.findViewById(R.id.VideoView);
return fragmentView;
}
@Override
public void onPause() {
super.onPause();
// Pause the video if it is playing
if (mVideoView.isPlaying()) {
mVideoView.pause();
}
// Save the current video position
mPosition = mVideoView.getCurrentPosition();
}
@Override
public void onResume() {
super.onResume();
mVideoView.setOnCompletionListener(this);
mVideoView.setOnPreparedListener(this);
mVideoView.setOnErrorListener(this);
mVideoView.setKeepScreenOn(true);
// Initialize the media controller
MediaController mediaController = new MediaController(getActivity());
mediaController.setMediaPlayer(mVideoView);
// Set-up the video view
mVideoView.setMediaController(mediaController);
mVideoView.requestFocus();
mVideoView.setVideoPath(mVideo.getUrl());
if (mVideoView != null) {
// Restore the video position
mVideoView.seekTo(mPosition);
mVideoView.requestFocus();
}
}
@Override
public void onDestroy() {
super.onDestroy();
// Clean-up
if (mVideoView != null) {
mVideoView.stopPlayback();
mVideoView = null;
}
}
@Override
public void onCompletion(MediaPlayer mediaPlayer) {
Log.e("VIDEO PLAY", "end video play");
}
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
// Start the video view
mediaPlayer.start();
Log.e("VIDEO PLAY", "video ready for playback");
}
@Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
Log.e("VIDEO PLAY", "error: " + i);
return true;
}
}
我不认为这是一些相关的上下文(应用程序或活动)..因为在视频和游戏显示的所有其他设备... 感谢您的帮助!
I don't think it's something related to context(Application or Activity).. because on all other devices the Video and the games are displayed.. Thanks for the help!
如果硬件加速解决您的问题,那么我会的启用该设备上的视图/窗口。
If hardware acceleration fixes your issue then I would enable it for that view/window on that device.
在一般我发现,当code工作在一个设备上,但不是另一个它通常是由下列问题之一:
In general I've found that when code works on one device but not another it is typically caused by one of the following problems:
的Bug在制造商的API实现 API的制造商不同的跨pretation 在自己的code并发问题(如竞争状态,不正确的同步),恰好触发更频繁地在特定设备上据我可以告诉你似乎可以用UI线程适当的,所以我会想象你的问题属于前两类之一,你只需要解决它。
As far as I can tell you seem to be using the UI thread appropriately so I would imagine your issue falls into one of the first two categories and you'll just need to work around it.
