使用融合位置 API 和应用程序意外崩溃

Using Fused Location API and App Crashing Unexpectedly

我正在使用 Google 融合位置 API 来获取设备的当前位置。出于测试目的,我只将位置保存到 TextView。我正在调用 LocationActivity on Menu Select 事件,但每当我单击菜单选项时,应用程序都会崩溃。

我查看了错误日志,但没有成功解决我的问题。请帮助我。

获取Activity:

public class LocationServiceActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener, LocationListener {

    Location mLocation;
    TextView latLng;
    GoogleApiClient mGoogleApiClient;

    private long FASTEST_INTERVAL = 5000;

        permissions.add(ACCESS_FINE_LOCATION);
