地理围栏,正在触发错误的挂起意图

在我的应用程序中,我有多个地理围栏,我希望它们具有唯一的待定意图,并具有不同的额外数据。但现在发生的是,对于我所有的地理围栏,正在触发的未决意图都是为最后一个地理围栏添加的,而不是分配给用户刚刚创建的特定地理围栏的。

例如,当我有2个地理围栏时,对于第一个,我会在挂起的意图中添加额外的字符串“AAA”,然后添加第二个带有额外“BBB”的地理围栏 然后输入第一个地理围栏,我将收到带有“BBB”的通知,而不是正确的“AAA” 我做错了什么?下面是我添加一个新地理围栏的代码:

public void addGeofencing(final MyObject myObject){

    Geofence geofence = (new Geofence.Builder()
            .setRequestId(myObject.getId())

            .setCircularRegion(
                myObject.getLat(),
                myObject.getLon(),
                RADIUS_IN_METERS
            )
            .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER |
                            Geofence.GEOFENCE_TRANSITION_EXIT)
            .setExpirationDuration(Geofence.NEVER_EXPIRE)
            .build());

            client.addGeofences(getGeofencingRequest(geofence),getGeofencePendingIntent(myObject.getExtraString))
                    .addOnSuccessListener(new OnSuccessListener<Void>() {
                        @Override
                        public void onSuccess(Void aVoid) {
                            System.out.println("GEOFENCE WORKED");
                        }
                    }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    System.out.println("GEOFENCE FAILED");
                }
            });

    }

    private GeofencingRequest getGeofencingRequest(Geofence geofence) {
        GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
        builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
        builder.addGeofence(geofence);
        return builder.build();
    }
    private PendingIntent getGeofencePendingIntent(String extraString) {
        Intent intent = new Intent(context, GeofenceTransitionsIntentService.class);
        intent.putExtra("extra",extraString);
        return PendingIntent.getService(context, 0, intent, FLAG_UPDATE_CURRENT);
    }
