我试图把视频作为动态壁纸。 我使用的媒体播放器的。我能得到SurfaceHolder，我可以给持有人的媒体播放器。 但它不是下面的异常工作对我来说，它给我

LogCat中的异常详细信息

  ERROR / AndroidRuntime（302）：java.lang.UnsupportedOperationException：壁纸不支持在保持屏幕
 

如果我不给媒体播放器它的工作原理给持有人，但我可以只听到声音。 我看到了一个应用程序VideoLiveWallpaper，它集视频作为动态壁纸，因此它可以是可能的，可能是我失去了一些东西。我粘贴code，有这方面的帮助将AP preciated。

ç段 $ C $

 公共无效surfaceCreated（SurfaceHolder持有者）{
  // TODO自动生成方法存根

 holder.setType（SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS）;
  熔点= MediaPlayer.create（getApplicationContext（），R.raw.sample）;
  mp.setDisplay（保持器）;
  mp.start（）;
 }
 

解决方案

我的猜测是，目前流通中的视频动态壁纸是用完全不同的方法：媒体手动解码，并绘制它逐帧。我不认为这个问题可以使用简单的方法加以解决 - 否则会有更多的人已经做到了

我假设你有这样的参考，但以防万一：的http：// forum.xda-developers.com/showthread.php?t=804720 在明确提及不同的视频格式使我相信开发人员正在做自己的解码... 祝你好运， 乔治

i am trying to put video as a live wallpaper. I am using media player for that. i can get SurfaceHolder and i can give that holder to the media player. But its not working for me, its giving me following exception

LogCat Exception Detail

ERROR/AndroidRuntime(302): java.lang.UnsupportedOperationException: Wallpapers do not support keep screen on

if i dont give holder to the media player it works, but i can hear only audio. I saw one application VideoLiveWallpaper , which set video as a live wallpaper, so it can be possible, may be i am missing something . I am pasting the code, any help on this will be appreciated.

Code Snippet

public void surfaceCreated(SurfaceHolder holder) {
  // TODO Auto-generated method stub

 holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
  mp=MediaPlayer.create(getApplicationContext(), R.raw.sample);
  mp.setDisplay(holder);
  mp.start();
 }

My guess is that the Video Live Wallpaper currently in circulation is using a totally different approach: decoding the media manually and drawing it frame by frame. I do not think this problem can be tackled using your simple method--otherwise more people would have already done it.

I assume you have this reference, but just in case: http://forum.xda-developers.com/showthread.php?t=804720 The explicit mention of differing video formats leads me to believe the developer is doing his own decoding... Good luck, George
