我尝试了每个代码和每个问题，在这里每次找到错误我都会修复一些东西 - 其他东西分解和方格框的网格覆盖所有的地图，如果我点击它，所有我需要的是而在地图上点击画出标记，并使用GPS在TextView中获得地址，这个输出看起来像this和我测试我的互联网连接仿真器和它的作品谷歌地图无法正常显示并强行关闭
这里是logcat的错误：

你能发布'logcat'信息呢？ –
抱歉，但无法导入我的logcat在这里，任何身体可以帮助我，我试过evey的东西！ – Weloo
我在一些书中读到，当应用程序响应速度不够快（我认为它的5秒钟）时，“强制关闭”会发生。如果是这种情况，请尝试将需要大量执行时间的代码移到另一个线程中。 –
