使用融合位置提供程序獲取位置

Question

我知道在stackoverflow上有很多關於融合位置管理器的問題。 但是沒人能解決我的問題。 所以：我使用官方文檔進行了簡單的上課

並注意到奇怪的動作。 我的onConnected方法從不調用。 我也檢查了onConnectionFailed，它是相同的。 問題是什么？

我的課：

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");
    }
}

我回答自己是因為我整天都丟失了它，也許有人會使用它。 如果您在AVD上測試應用程序，請記住每次都要清理應用程序緩存-多次運行同一應用程序會導致並非代碼中所做的所有更改都更新為AVD ...
