Question

我想在android中实现自动完成位置google API。为此，我需要创建一个GoogleApiClient对象。我已经使用了以下代码...

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();

但是当片段启动时，它会抛出以下异常并且应用程序崩溃。

java.lang.IllegalStateException：已经在管理GoogleApiClient id为

注意：这是在FRAGMENT中执行的。

以下是清单文件配置..

所以，请帮助解决这个问题..

谢谢。

Answer 1

在您的代码中尝试此操作

@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，您不必使用

mGoogleApiClient.stopAutoManage((Activity) context);

因为它将由图书馆自己照顾。

这就是我为片段制作的方式：

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 for the fragment：

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

片段的

onDestroy：

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

我在 onCreate（）

中运行 buildGoogleApiClient（）方法

然后我在我的XML中使用MapView作为我的片段，如下所示：

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

然后在 onCreateView 的片段中，我执行以下操作：

@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;
}

如果使用导航工具进行导航，我在加载片段时遇到了问题，然后再次按下导航菜单项，然后崩溃，以解决我这样做：

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;
        }

创建GoogleApiClient对象时出错，给出java.lang.IllegalStateException：已经管理了ID为0的GoogleApiClient
