Android 使用融合位置提供程序获取位置

我知道stackoverflow上有很多关于fused location manager的问题。但没人能解决我的问题。因此： 我用官方软件制作了一个简单的类

注意奇怪的动作。从未调用我的onConnected方法。我还检查了onConnectionFailed，结果是一样的。 有什么问题

我的班级：

public class MapActivity extends FragmentActivity implements OnMapReadyCallback, LocationListener, GoogleMap.OnMarkerClickListener
, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{

    private GoogleMap mMap;
    private double naviLat, naviLong;
    private double latitude, longitude;
    private GoogleApiClient mGoogleApiClient;

    @BindView(R.id.adView)
    AdView adView;
    @BindView(R.id.butnavi)
    ImageButton butnavi;
    private GPStracker gpStracker;
    private Location location;
    private RealmResults<RowModel> rowModels;
    private String shopName;
    private Bundle bundle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map2);
        ButterKnife.bind(this);

        if (mGoogleApiClient == null) {
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .addApi(LocationServices.API)
                    .build();
        }
        mGoogleApiClient.connect();



        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(map);
        mapFragment.getMapAsync(this);


        mapFragment.getMapAsync(this);

        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }



    @Override
    public void onConnected(Bundle connectionHint) {
        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(this, "Uprawnienia nie przyznane", Toast.LENGTH_SHORT).show();
        }
        Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            Log.d("ddsa", String.valueOf(mLastLocation.getLatitude()) + " " +
            String.valueOf(mLastLocation.getLongitude()));
        }
    }



    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
        Log.d("aaa", "Failed");
    }
}

我回答我自己，因为我一整天都把它弄丢了，也许有人会用它。如果您在AVD上测试应用程序，请记住每次都要清理应用程序缓存-运行多次相同的应用程序会导致并非所有对AVD进行的代码更新更改…

设备上是否安装了播放服务并且是最新的？调用了onConnectionFailed？您是否具有运行时位置权限？？？@Ryan我测试了它所以我认为google play服务应该达到date@xabadalonConnectionFailed我认为应该在onConnection为false时自动调用。但它也不起作用。
