解决方案

您正在使用 onCreate()方法请求位置更新.应在 onConnected()中调用

一旦GoogleAPIClient成功连接,就会回调.

LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;

解决方案

You are requesting location updates in the onCreate() method.This should be called in the onConnected() callback once the GoogleAPIClient has connected succesfully.

LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
