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。

我昨天实现了这个https://developers.google.com/android/reference/com/google/android/gms/location/SettingsApi，它工作正常。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，会弹出要求我打开位置的窗口，但无论我点击多少次，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工作。 ..

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

            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) {

Answer 1

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

public abstract void disconnect()

关闭与 Google Play 服务的连接。调用此方法后，无法使用此客户端进行调用。

您正在使用onPause() 方法断开客户端连接，因此一旦您调用startResolutionForResult()，您的GoogleApiClient 就不再有效。您无需像取消注册并重新注册BroadcastReceiver 那样停止并重新启动客户端。从同一页面的顶部：

您应该在 Activity 的 onCreate(Bundle) 方法中实例化一个客户端对象，然后在 onStart() 中调用 connect() 并在 onStop() 中调用 disconnect()，无论状态如何。
