安卓 : not able to add geofence from service

Question

我无法从服务类别添加地理围栏。下面是我的代码:

问题:

我能够获得“已添加地理围栏”的 toast 。但是当我选择当前位置进行击剑时，它不会触发任何通知。之前，当我从 Activity 中执行此操作时，如果我的设备位置位于我添加的围栏中，它会触发通知。

请帮我找出问题所在。

谢谢。

我是这样做的:

我创建了 GeoFenceObserversationService singleton 类。

GeoFenceObserversationService.java:

public class GeoFenceObserversationService extends Service implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<Status> {

    protected static final String TAG = "GeoFenceObserversationService";
    protected GoogleApiClient mGoogleApiClient;
    protected ArrayList<Geofence> mGeofenceList;
    private boolean mGeofencesAdded;
    private SharedPreferences mSharedPreferences;
    private static GeoFenceObserversationService mInstant;
    public static GeoFenceObserversationService getInstant(){
        return mInstant;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        mInstant = this;
        mGeofenceList = new ArrayList<Geofence>();
        mSharedPreferences = getSharedPreferences(AppConstants.SHARED_PREFERENCES_NAME, MODE_PRIVATE);
        mGeofencesAdded = mSharedPreferences.getBoolean(AppConstants.GEOFENCES_ADDED_KEY, false);

        buildGoogleApiClient();
    }


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

    @Nullable

应用程序常数:

   public static final String SHARED_PREFERENCES_NAME = PACKAGE_NAME + ".SHARED_PREFERENCES_NAME";
    public static final String GEOFENCES_ADDED_KEY = PACKAGE_NAME + ".GEOFENCES_ADDED_KEY";
    public static final String DETECTED_GEOFENCES = "detected_geofences";
    public static final String DETECTED_BEACONS = "detected_beacons";

    public static String getErrorString(Context context, int errorCode) {
        Resources mResources = context.getResources();
        switch (errorCode) {
            case GeofenceStatusCodes.GEOFENCE_NOT_AVAILABLE:
                return mResources.getString(R.string.geofence_not_available);
            case GeofenceStatusCodes.GEOFENCE_TOO_MANY_GEOFENCES:
                return mResources.getString(R.string.geofence_too_many_geofences);
            case GeofenceStatusCodes.GEOFENCE_TOO_MANY_PENDING_INTENTS:
                return mResources.getString(R.string.geofence_too_many_pending_intents);
            default:
                return mResources.getString(R.string.unknown_geofence_error);
        }
    }

我从哪里开始服务？来自应用程序类

• startService(new Intent(getApplicationContext(),GeoFenceObserversationService.class));

我如何注册地理围栏？

• GeoFenceObserversationService.getInstant().addGeofences();

希望这对您有帮助。
