私のジオフェンスは最初は機能していましたが、1 日か 2 日後に突然トリガーが停止しました。Google 側または私のコードに問題がありますか?
アプリを起動して開始すると、ジオフェンスを登録する IntentService を使用します。

この：
public class GeofenceReceiver extends BroadcastReceiver {
...
@Override
public void onReceive(Context context, Intent intent) {
this.context = context;
GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
if(geofencingEvent.hasError()) {
String errorMessage = GeoErrorMessages.getErrorString(context, geofencingEvent.getErrorCode());
Log.e(TAG, errorMessage);
return;
}
int geofenceTransition = geofencingEvent.getGeofenceTransition();
if(geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER || geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {
// Do stuff
}
...
また、私が試して修正したと思ったことの回答も参照してください。しかし、それは役に立ちませんでした。
