动态壁纸崩溃,下面的代码
public void render(){
Canvas canvas = null;
try{
canvas = this._surfaceHolder.lockCanvas(null);
synchronized (this._surfaceHolder) {
this.onDraw(canvas);
}
}catch(Exception e){ Log.w("Surface holder ",e.toString());}
finally{
if(canvas != null){
this._surfaceHolder.unlockCanvasAndPost(canvas);
}
}
}

解决方法
当您在动态壁纸选择器中旋转设备时,通常会发生这种情况.我发现唯一的解决方案是捕获IllegalArgumentException并忽略它.
if (canvas != null) {
try {
holder.unlockCanvasAndPost(canvas);
} catch (IllegalArgumentException e) {
// Ignore weird bug when rotating in live wallpaper picker
}
}
