【问题描述】：

我尝试按照http://developer.android.com/training/location/retrieve-current.html 的指南获取当前位置

我的 google play 服务已启动，但我的 locationclient 仍然无法连接，并且在我运行程序时出现这些错误。（PS：以前我的位置码可以用，现在不行，奇怪）

【问题讨论】：

检查您是否将 googleplay 服务库添加到您的项目中
我添加了...然后我再去添加
第 51 行中的内容..
@Aravinth 那个空行？

标签： android location location-client

【解决方案1】：

看这里

Not connected. Call connect() and wait for onConnected() to be called.

你应该调用.connect() ..然后执行onConnected()中的方法。

因为如果它没有连接，而你试图访问互联网，它会崩溃。

【讨论】：

我把 .connect() 放到 onConnected() 上，还是一样的问题，我认为应该在 onStart() 下，因为在这个活动开始时连接。sa
不！首先你应该连接到套接字.. 然后如果连接为真， onConnect 中的方法将被创建
你的意思是连接到套接字？但无论如何，即使将 connect() 添加到 Onconnected() 监听器，它仍然是同样的问题
** mLLocationClient.connect(); ** 应该在 oncreate 的 setconectview 下
同样的问题发生了:(

【解决方案2】：

对我来说似乎有问题的是mLocationClient.connect(); 在onConnected() 方法内，因为onConnected() 是GooglePlayServicesClient.ConnectionCallbacks 接口的方法，当LocationClient 连接到谷歌服务时调用onConnected()，这发生在调用mLocationclient.connect() 方法。您应该在其他地方使用mLocationClient.connect() 方法，例如onResume() 或onStart()。
