调用 requestLocationUpdates() 时出现 IllegalStateException

Question

我正在开发一个经常使用谷歌地图的应用程序。我经常将此方法称为 requestLocationUpadates() 方法，有时此方法会抛出 IllegalStateException。下面粘贴的是引发异常和日志消息的代码。非常感谢任何帮助。谢谢！！

gpsLocationDailog.cancel();
if (mLocationClient == null)
mLocationClient = new LocationClient(getApplicationContext(),
                    this, this);
mLocationClient.requestLocationUpdates(REQUEST, this);
mCurrentLocation = mLocationClient.getLastLocation();
fireQueryToGetTheResponse(latitude, longitude);
rl.setVisibility(View.VISIBLE);

这是日志消息
