无法在地理Geofence中得到警报

Question

Location Services is available
Client connected
Add Geofences: Success GeofenceRequestIds=[1, 2]
com.example.android.geofence.ACTION_GEOFENCES_ADDED

在通过stackoverflow读取几个线程之后，我甚至尝试在CreateRequestPendingIntent函数中用GetBroadcast()替换GetService()，但没有成功。

我也试过

**Geofence #1 and Geofence #2**

Lat : 23.039568000000003
Lng : 72.56600400000002
Radius :1

而且我也设置了我目前在genymotion的位置以上的坐标，使其工作，但没有通知。

Answer 1

你设置的半径太小，谷歌播放服务不给1米的通知，当你增加半径，它给了更好的结果，为地理围栏尝试。

在GeofenceReceiver中

Intent broadcastIntent = new Intent();
@Override
public void onReceive(Context context, Intent intent) {
    this.context = context;

    broadcastIntent.addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES);

    if (LocationClient.hasError(intent)) {
        handleError(intent);
    } else {
        handleEnterExit(intent);
    }
}

private void handleError(Intent intent) {
    // Get the error code
    int errorCode = LocationClient.getErrorCode(intent);

    // Get the error message
    String errorMessage = LocationServiceErrorMessages.getErrorString(
            context, errorCode);

    // Log the error
    Log.e(GeofenceUtils.APPTAG, context.getString(
            R.string.geofence_transition_error_detail, errorMessage));

    // Set the action and error message for the broadcast intent
    broadcastIntent.setAction(GeofenceUtils.ACTION_GEOFENCE_ERROR)
            .putExtra(GeofenceUtils.EXTRA_GEOFENCE_STATUS, errorMessage);

    // Broadcast the error *locally* to other components in this app
    LocalBroadcastManager.getInstance(context).sendBroadcast(
            broadcastIntent);
}

private void handleEnterExit(Intent intent) {
    // Get the type of transition (entry or exit)
    int transition = LocationClient.getGeofenceTransition(intent);

    // Test that a valid transition was reported
    if ((transition == Geofence.GEOFENCE_TRANSITION_ENTER)
            || (transition == Geofence.GEOFENCE_TRANSITION_EXIT)) {

        // Post a notification
        List<Geofence> geofences = LocationClient
                .getTriggeringGeofences(intent);
        String[] geofenceIds = new String[geofences.size()];
        String ids = TextUtils.join(GeofenceUtils.GEOFENCE_ID_DELIMITER,
                geofenceIds);
        String transitionType = getTransitionString(transition);
        sendNotification(transitionType, ids);

        for (int index = 0; index < geofences.size(); index++) {
            Geofence geofence = geofences.get(index);

        }
        // Create an Intent to broadcast to the app
        broadcastIntent
                .setAction(GeofenceUtils.ACTION_GEOFENCE_TRANSITION)
                .addCategory(GeofenceUtils.CATEGORY_LOCATION_SERVICES);

        LocalBroadcastManager.getInstance(sqlitewraper.context)
                .sendBroadcast(broadcastIntent);

        // Log the transition type and a message
        Log.d(GeofenceUtils.APPTAG, transitionType + ": " + ids);
        Log.d(GeofenceUtils.APPTAG, context
                .getString(R.string.geofence_transition_notification_text));

        // In debug mode, log the result
        Log.d(GeofenceUtils.APPTAG, "transition");

        // An invalid transition was reported
    } else {
        // Always log as an error
        Log.e(GeofenceUtils.APPTAG, context.getString(
                R.string.geofence_transition_invalid_type, transition));
    }
}

private void sendNotification(String transitionType, String locationName) {

    // Create an explicit content Intent that starts the main Activity
    Intent notificationIntent = new Intent(sqlitewraper.context,
            MainActivity.class);

    // Construct a task stack

            default:

更改示例代码GeofenceRequester

    Intent intent = new Intent("packagename.ACTION_RECEIVE_GEOFENCE");

//  Intent intent = new Intent(mActivity, ReceiveTransitionsIntentService.class);


return PendingIntent.getBroadcast(

                   sqlitewraper.context,
                    0,
                   intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);
        }
