当我上载没有Internet连接的文档时，我的加载器屏幕没有隐藏，因为firestore无法通过onSuccessListener或onFailureListener传递，而且我无法调用“ hideProgress（）”方法。但是，如果我关闭该应用程序然后再次打开它，则新文档将正确添加到数据库中。我应该如何处理没有互联网连接？
那是我的代码：
fun updateExercise(userId: String, documentId: String, exercise: DiaryRequest) {
FirebaseFirestore.setLoggingEnabled(true)
try {
db.collection("utenti")
.document(userId)
.collection("diario")
.document(documentId)
.set(exercise, SetOptions.merge())
.addOnSuccessListener {
mView.onUploadCompleted()
}
.addOnFailureListener {
mView.onUploadCompleted()
}
}catch (e: UnknownHostException){
mView.onUploadCompleted()
}
}
这是一条日志：
