创建googleapicclient对象错误，给出java.lang.IllegalStateException:已经管

Question

我想实现自动完成的地方谷歌API在android。为此，我需要创建一个googleapicclient对象。我使用了以下代码:

private GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .addApi(Drive.API)
                .addScope(Drive.SCOPE_FILE)
                .enableAutoManage(getActivity(), 0 /* clientId */, this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

但是当片段开始时，它会抛出以下异常，并导致应用程序崩溃。

. lang。IllegalStateException:已经管理一个googleapicclientid为0

注意:这在FRAGMENT中执行

下面是manifest文件的配置。

所以，请帮忙解决这个问题。

谢谢。

Answer 1

在你的代码中试试

@Override
public void onStart() {
    super.onStart();
    if (mGoogleApiClient != null)
    mGoogleApiClient.connect();
}
@Override
public void onStop() {
    super.onStop();
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        mGoogleApiClient.stopAutoManage((Activity) context);
        mGoogleApiClient.disconnect();
    }
}

注意:从playstore版本10开始，你不必使用

mGoogleApiClient.stopAutoManage((Activity) context);

Answer 2

这是我如何为我的片段:

片段代码:

private synchronized void buildGoogleApiClient() {
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
            .enableAutoManage(getActivity(), this)
            .addConnectionCallbacks(this)
            .addApi(LocationServices.API)
            .build();
    createLocaitonRequest();
}
private void createLocaitonRequest() {
    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}

onStart:

@Override
public void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}

onDestroy:

@Override
public void onDestroy() {
    super.onDestroy();
    mGoogleApiClient.stopAutoManage(getActivity());
    mGoogleApiClient.disconnect();
}

我运行buildGoogleApiClient()方法在onCreate()

然后我使用MapView在我的XML为我的片段如下:

<com.google.android.gms.maps.MapView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/map" />

然后在我的片段当onCreateView我做以下操作:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    mView = inflater.inflate(R.layout.fragment_maps, container, false);
    setRetainInstance(true);
    setupMapsFragment(mView);
    mMapView = (MapView) mView.findViewById(R.id.map);
    if (mMapView != null) {
        mMapView.onCreate(null);
        mMapView.onResume();
        mMapView.getMapAsync(this);
    }
    return mView;
}

如果导航是用navigationdrawer制作的，我确实得到了你的问题，当我加载片段然后再次按下导航菜单项，然后它崩溃了，所以为了解决这个问题，我这样做:

if (id == R.id.nav_map) {
        if(checkMapsFragment == true){
            Toast.makeText(this,"map is already loaded",Toast.LENGTH_LONG).show();
        }
        if(checkMapsFragment == false){
            fragment = new MapsFragment();
            checkMapsFragment = true;
        }
