触发后删除地理围栏
作者:互联网
我在应用程序中使用了地理围栏,除删除触发的地理围栏外,其他所有功能均正常.
我从Android的官方文档中删除了该指南,但它们没有说明如何删除IntentService内部的地理围栏.
这是服务的事件处理程序的代码:
@Override
protected void onHandleIntent(Intent intent)
{
Log.e("GeofenceIntentService", "Location handled");
if (LocationClient.hasError(intent))
{
int errorCode = LocationClient.getErrorCode(intent);
Log.e("GeofenceIntentService", "Location Services error: " + Integer.toString(errorCode));
}
else
{
int transitionType = LocationClient.getGeofenceTransition(intent);
if (transitionType == Geofence.GEOFENCE_TRANSITION_ENTER)
{
List <Geofence> triggerList = LocationClient.getTriggeringGeofences(intent);
String[] triggerIds = new String[triggerList.size()];
for (int i = 0; i < triggerIds.length; i++)
{
// Store the Id of each geofence
triggerIds[i] = triggerList.get(i).getRequestId();
Picture p = PicturesManager.getById(triggerIds[i], getApplicationContext());
/* ... do a lot of work here ... */
}
}
else
Log.e("ReceiveTransitionsIntentService", "Geofence transition error: " + Integer.toString(transitionType));
}
}
他被触发后,如何删除地理围栏?
解决方法:
您可以执行以下操作:
LocationServices.GeofencingApi.removeGeofences(
mGoogleApiClient,
// This is the same pending intent that was used in addGeofences().
getGeofencePendingIntent()
).setResultCallback(this); // Result processed in onResult().
而且您的getGeofencePendingIntent()方法如下所示:
/**
* Gets a PendingIntent to send with the request to add or remove Geofences. Location Services
* issues the Intent inside this PendingIntent whenever a geofence transition occurs for the
* current list of geofences.
*
* @return A PendingIntent for the IntentService that handles geofence transitions.
*/
private PendingIntent getGeofencePendingIntent() {
Log.d(TAG, "getGeofencePendingIntent()");
// Reuse the PendingIntent if we already have it.
if (mGeofencePendingIntent != null) {
return mGeofencePendingIntent;
}
Intent intent = new Intent(mContext, GeofenceIntentServiceStub.class);
// We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when calling
// addGeofences() and removeGeofences().
mGeofencePendingIntent = PendingIntent.getService(mContext, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
return mGeofencePendingIntent;
}
