我每次开机只要一选择这个launcher就会报这样的错，可是把他的错误提示框点掉之后程序依旧可以运行，没什么不对的。直到下一次开机选择这个launcher就还会有这个错误，Make sure the SurfaceView or associated SurfaceHolder has a valid Surface这个错误怎么解决啊，坐等大神。

[解决办法]
要在surfaceCreated 之后才把surfaceHolder传到系统函数进去。
surfaceChanged之后也要及时更新。


public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
surfaceHolder = holder ;
Log.v(TAG, "surfacedChanged " + "width="+width+"height="+height+"Format="+format) ;

}

public void surfaceCreated(SurfaceHolder holder) {
Log.v(TAG, "surfacedCreated " ) ;
surfaceHolder = holder ;
}
