Android locationClient未连接从OnConnected内部引发的异常

我有一个使用geo fences的Android应用程序，正在以下代码中添加：

public void register(ArrayList<Geofence> geofences){
        if(geofences == null || geofences.size() == 0) return;
        this.geofences = geofences;
        locationClient = new LocationClient(context, this, onConnectionFailedListener);
        locationClient.connect();
    }

    @Override
    public void onConnected(Bundle bundle) {
        locationClient.addGeofences(geofences, GeofenceBroadcastReceiver.getPendingIntent(context), this);
    }

    @Override
    public void onDisconnected() {
        this.locationClient = null;
    }

    @Override
    public void onAddGeofencesResult(int statusCode, String[] strings) {
        if(statusCode != LocationStatusCodes.SUCCESS){
            Log.e(getClass().getName(), "onAddGeofencesResult: " + statusCode);
            return;
        }

        listener.addRegistered(strings);
        locationClient.disconnect();
    }

如果出现异常，locationClient未连接，但代码正在从onConnected方法中删除

有人能给我指出正确的方向吗？我的develop Galaxy S4似乎无法重现此错误。

您应该设置连接请求

locationClient.requestLocationUpdates(REQUEST, this);

下面是我如何解决这个问题的。我只是捕获IllegalStateException，然后处理事件，就好像没有位置提供程序一样（ShowDefaultLocationData（）是一种在没有GPS可用时处理事件的方法）

locationClient.requestLocationUpdates(REQUEST, this);

private void requestLocation() {
        if (servicesConnected()) {
            LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
            if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
                updateLocation = true;
                mLocationRequest = LocationRequest.create();
                mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
                mLocationRequest.setInterval(5000);
                mLocationRequest.setFastestInterval(1000);
                mLocationClient = new LocationClient(this, this, this);
                mLocationClient.connect();
            }
        } else
        {
            ShowDefaultLocationData();
        }
    }


@Override
public void onConnected(Bundle connectionHint) {
    try {
        mLocationClient.requestLocationUpdates(mLocationRequest, MainActivity.this);
        isconnected = true;
    } catch (IllegalStateException e) {
        ShowDefaultLocationData();
    }
}
