onLocationChanged不叫检索位置 [英] onLocationChanged not called to retrieve position

问题描述

我在开发使用 Google地图API ，现在它工作得很好到我的app.Few天前用来测试我的实际设备应用程序我做我的平板电脑的硬复位，当我试图再次测试我的应用程序，这并不像before.so我logcat中我看到 locationClient 连接工作，但它不能识别我的位置，所以 onLocationChanged 永远不会被调用。

I' m developing an app that use the google maps api, now it worked fine into my real device which i used to the test the app.Few days ago i made an hard reset on my tablet and when i tried to test my app again, it didn't work as before.so in my logcat i see that the locationClient is connected, but it can't recognize my position, so onLocationChanged is never called.

我注意到这一点到我logcat的：

i notice this into my logcat:

I/Google Maps Android API(2924): Google Play services client version: 5089000
I/Google Maps Android API(2924): Google Play services package version: 5089032

我知道，这是两个不同版本的谷歌播放服务，我可以不知道如何解决它，因为之前平板电脑的硬复位，我没有得到这个信息到logcat的。

i know that these are two different versions of google play services, i can't understand how to fix it, because before tablet's hard reset,i hadn't got this info into logcat.

这是我的manifest.xml：

this is my manifest.xml:

                .setFastestInterval(FASTEST_INTERVAL).setSmallestDisplacement(10);
        if (locationClient != null)
            // connect the client to the Google Play services
            locationClient.connect();
    }

    @Override
    public void onLocationChanged(Location location) {
        //THIS IS NEVER CALLED
        newPosition = new LatLng(location.getLatitude(), location.getLongitude());
        myLocation = location;
        map.animateCamera(CameraUpdateFactory.newLatLngZoom(newPosition, 15));
    }

    @Override
    public void onConnected(Bundle arg0) {
        //*************************** AT THE BEGINNING THIS IS CALLED***************/
        // BUT onLocationChanged is never called
        Toast.makeText(this, "I'm bringing you to your area.", Toast.LENGTH_SHORT).show();
        locationClient.requestLocationUpdates(locationRequest, this);
    }

    @Override
    public void onDisconnected() {
        Toast.makeText(this, "Disconnected. Please re-connect.", Toast.LENGTH_SHORT).show();
    }

    [...]
