ResultInfo - java.lang.IllegalStateException：GoogleApiClient 尚未连接

Question

我阅读了其他类似的问题，但找不到解决方案。

我昨天实施了这个 https://developers.google.com/android/reference/com/google/android/gms/location/SettingsApi 并且运行良好。今天我不知道我在项目中搞砸了什么。当我输入片段并且位置被禁用时，会弹出 window 要求我打开位置，但无论我点击多少次“否”，它都不会消失，或者如果我点击“是”，我会进入 logcat

基本上在 onActivityResult 中 googleClient 为空。正如我昨天所说的那样。 ..

TestLocation 片段：

public class TestLocation extends Fragment implements
            GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {


        public TestLocation() {
        }

        private static GoogleApiClient googleClient;
        private Location mLastLocation;
        private PendingResult<LocationSettingsResult> result;
        private LocationRequest locationRequest;



        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            if (googleClient==null) {
                googleClient = new GoogleApiClient.Builder(getActivity())
                        .addApi(LocationServices.API)
                        .addConnectionCallbacks(this)
                        .addOnConnectionFailedListener(this)
                        .build();
            }
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
 super.onCreateView(inflater, container, savedInstanceState);
            // Defines the xml file for the fragment
            View view = inflater.inflate(R.layout.upload_activity_fragment, container, false);
            return view;
        }


        @Override

        }


        @Override

            locationRequest = LocationRequest.create();
            locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

            LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                    .addLocationRequest(locationRequest);

            builder.setAlwaysShow(true);
            result = LocationServices.SettingsApi.checkLocationSettings(googleClient, builder.build());

            if (result != null) {
                result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
                    @Override
                    public void onResult(LocationSettingsResult locationSettingsResult) {
                        final Status status = locationSettingsResult.getStatus();
                        switch (status.getStatusCode()) {
                            case LocationSettingsStatusCodes.SUCCESS:

                                // settings so we won't show the optionsDialog.
                                break;
                        }

        }

Answer 1

来自 Google API 对 GoogleApiClient#disconnect() 方法的参考：

public abstract void disconnect ()

Closes the connection to Google Play services. No calls can be made using this client after calling this method.

您正在 onPause() 方法中断开客户端连接，因此一旦您调用 startResolutionForResult()，您的 GoogleApiClient 就不再有效。您不需要像注销和重新注册 BroadcastReceiver 那样停止并重新启动客户端。从同一页面的顶部：

You should instantiate a client object in your Activity's onCreate(Bundle) method and then call connect() in onStart() and disconnect() in onStop(), regardless of the state.
