GoogleApiClient無法在android studio中連接

Question

我一段時間無法連接google map api客戶端。 即使對象返回的值也不為null，但仍然無法連接。 我也在清單中提到了權限

下面是我的代碼

 public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        buildGoogleApiClient();
}

         protected synchronized void buildGoogleApiClient(){
        googleApiClient = new GoogleApiClient.Builder(getBaseContext())
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        googleApiClient.connect();
}
@Override
public void onConnected(@Nullable Bundle bundle) {
    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(1000);
    mLocationRequest.setFastestInterval(1000);
    mLocationRequest.setPriority(mLocationRequest.PRIORITY_HIGH_ACCURACY);

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

        return;
    }
   // 

LocationServices.getFusedLocationProviderClient(this).requestLocationUpdates(mLocationRequest,new LocationCallback());
        LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, mLocationRequest, (com.google.android.gms.location.LocationListener) this);
    }

我的gradle依賴看起來像這樣

 dependencies {
        implementation fileTree(include: ['*.jar'], dir: 'libs')
        implementation 'com.android.support:appcompat-v7:26.1.0'
        implementation 'com.google.android.gms:play-services-maps:15.0.1'
        implementation 'com.google.android.gms:play-services-vision:15.0.2'
        implementation 'com.google.android.gms:play-services-location:15.0.1'
        implementation 'com.google.android.gms:play-services-maps:15.0.1'

        implementation 'com.google.firebase:firebase-core:16.0.1'
        implementation 'com.google.firebase:firebase-database:16.0.1'
        implementation 'com.android.support:design:26.1.0'
        implementation 'com.android.support.constraint:constraint-layout:1.1.2'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test:runner:1.0.2'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    }
    apply plugin: 'com.google.gms.google-services'

我是Google Maps項目的新手，對此一無所知。 如果有人有解決方案，請幫助我。 提前致謝

我通過在我使用的公共類中實現GoogleApiClient.OnConnectionFailedListener來解決此問題。 您可能還沒有這樣做，這是它連接到API所必需的。
