Question

我已经运行了Geofence样本，并且已经分配了两组Lat，Lng和radius并运行样本。当我点击寄存器地理围栏时，我正在记录日志中的内容

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

但之后没有任何反应，我不知道我通过启用gps但没有效果通过当前位置的问题。

我不知道什么时候我会在越过栅栏时收到通知，为了测试它我已经通过了击剑中相同的地理坐标，但仍然没有警报。

在stackoverflow上读取几个线程后，我甚至尝试在getService()函数内用getBroadcast()替换createRequestPendingIntent，但没有运气。

我也尝试了

**Geofence #1 and Geofence #2**

Lat : 23.039568000000003
Lng : 72.56600400000002
Radius :1

我还将我目前在genymotion中的位置设置为高于坐标，以使其工作但没有通知。

即使在真实的设备上，我的3G也已启用，我正在使用该设备，但到目前为止没有任何变化。

你设置半径太小google-play服务当你增加半径时不给1米通知它给出更好的结果并尝试进行地理围栏。

GeofenceReceiver中的

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));

    broadcastIntent.setAction(GeofenceUtils.ACTION_GEOFENCE_ERROR)
            .putExtra(GeofenceUtils.EXTRA_GEOFENCE_STATUS, errorMessage);

        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++) {

        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 {

        Log.e(GeofenceUtils.APPTAG, context.getString(

private void sendNotification(String transitionType, String locationName) {

    // Create an explicit content Intent that starts the main Activity

            default:

        return ("Transisation unknown");
        }
 }

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);
        }

更改清单文件

<receiver android:name="packagename.GeofenceReceiver"
            android:exported="false" >
            <intent-filter>
                <action android:name="packagename.ACTION_RECEIVE_GEOFENCE" />
