我的'游戏'在我恢复之后不断崩溃。基本上,我启动应用程序,一切正常。然后我按下主页按钮返回主屏幕。仍然是所有正常的东西。但是,当我打开应用程序时,它只是冻结,大约1分钟后,我收到一条无响应的消息。
这是我的主要活动:

class FastRenderView extends SurfaceView implements Runnable

}
}
}
@Override
public void run()
{

{
if(!holder.getSurface().isValid())
continue;
Canvas canvas = holder.lockCanvas();
onDraw(canvas);
holder.unlockCanvasAndPost(canvas);
}
}
public void onDraw(Canvas canvas)
{
canvas.drawRGB(255, 255, 255);
player.onDraw(canvas);
}
}
class mainGameThread extends Thread
{

{
super("mainGameThread");
start();
}
public void run()
{
try{
player.onUpdate();
}catch(Exception e){

}
}
}
非常感谢任何帮助。
这是我的logcat输出:http://pastebin.com/3b09YAkP 我有一个主游戏线程,因为我读到如果渲染线程卡住2秒钟,它会崩溃。

看起来它可能是两件事之一。
您可能应该在onPause()
中明确暂停您的主题。如果它试图在没有暂停的情况下恢复,那么这可能会导致应用程序死锁。
您还应该查看Replica Island上的Google I / O演示文稿。大约一个小时。记下他谈论垃圾收集的部分。这可能是正在发生的事情并导致您的应用因ANR错误而崩溃。
我希望这有帮助!
