为什么我的听众在此Firestore中没有被击中 [英] Why is not the my listeners hit here in this Firestore set

问题描述

我有一个奇怪的地方，OnSuccessListener或OnFailureListener不再被调用.一切正常，但是当我打开移动数据并呼叫OnSuccessListener或OnFailureListener以外的Wifi时.

I have this strange thing where OnSuccessListener or OnFailureListener stopped being called. Everything works ok but when I turn of mobile data and Wifi non of the OnSuccessListener or OnFailureListener is being called.

如果我在下面的代码ref.set(update).....上放置一个断点，则确实会命中断点，但OnSuccessListener或OnFailureListener不会触发

If I put a breakpoints on the below code ref.set(update)..... the breakpoints are indeed hit but non of the OnSuccessListener or OnFailureListener fires

 Map<String, String> update = new HashMap<>();
    update.put(ByteData.DATA, data);
    DocumentReference ref = firestore
            .collection(DEVICE_DATA)
            .document(FirestoreManager.getInstance().getUserId())
            .collection(DEVICE_DATA_STREAM)
            .document(batteryEntity.getEntityId());
    ref.set(update).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
             // do some stuff
        }
    }).addOnSuccessListener(new OnSuccessListener<Void>() {
        @Override
        public void onSuccess(Void aVoid) {
             // do some stuff
        }
    });

推荐答案

当我打开移动数据并使用Wifi上网时[c0>或OnFailureListener都没有被调用

这是预期的行为.仅当数据已写入服务器(或被服务器拒绝)后，才会调用完成侦听器.

That is the expected behavior. The completion listeners are only called once the data has been written on (or rejected by) the server.

监听器不会为本地写入操作触发.如果本地写操作失败，则客户端将引发常规异常.

The listener doesn't fire for local write operation. If the local write operation were to fail, the client will raise a regular exception.
