Can'；使用Google Play Services API Android无法获取用户位置

我一直在尝试在我的android应用程序中使用

Google Play Services

获取用户位置，但

MapsActivity

似乎无法更新位置。我尝试了三个教程，但似乎没有一个能解决获取用户位置的问题

MapsActivity.java

    if (googleApiClient.isConnected()) {
        LocationServices.FusedLocationApi.removeLocationUpdates(googleApiClient, this);
        googleApiClient.disconnect();
    }
}

/**

@Override

    map = googleMap;

    LatLng latLng = new LatLng(0, 0);
    map.addMarker(new MarkerOptions().position(latLng).title("Marker"));

private void handleNewLocation(Location location) {
    Log.d(TAG, location.toString());
    double currentLatitude = location.getLatitude();
    double currentLongitude = location.getLongitude();
    LatLng latLng = new LatLng(currentLatitude, currentLongitude);
    MarkerOptions options = new MarkerOptions()

    }
}

@Override
public void onLocationChanged(Location location) {
    handleNewLocation(location);
}
}

我还向我的

AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

我已将依赖项更改为：

compile 'com.google.android.gms:play-services:10.2.0'

---

但这并没有解决问题。

MapsActivity

将坚持默认的

LatLag（0,0）

。任何帮助都将不胜感激。

当您调试时，您在onConnected方法Location lastLocation=LocationServices.FusedLocationApi.getLastLocation（GoogleAppClient）中得到了什么；不，我没有收到任何错误。是的，我正在运行棉花糖模拟器。您是否在控制台中收到警告，表示您没有请求运行时权限？不，我没有收到任何警告，当您调试时，您在该行得到了什么？该行在传递给handleNewLocation方法之前是否返回（0,0）？

compile 'com.google.android.gms:play-services:10.2.0'
