KOTLIN/FIREBASE Error when I try get data from firebase database - Client is offline

Matthew Kna

When i try get user information by his uid which is same like in firebase database this error is shown.

enter image description here

uid is passed in right way I have checked it. Route to database is good and I have checked this too.

Here is my code and this probably don't have any mistakes because everything work and only Firebase had some problems.

class Profil : AppCompatActivity() {

    private var fAuth: FirebaseAuth?=null
    private var database: DatabaseReference?=null

    override fun onCreate(savedInstanceState: Bundle?) {

        fAuth= FirebaseAuth.getInstance()

        // ✋ Here I checked with uid and uid.toString()

        var userCheck = fAuth!!.currentUser?.uid.toString()


        // ✋ Here I checked that good uid is get

        //tv_firsName.text = userCheck

    private fun getData(userCheck: String) {

        database = FirebaseDatabase.getInstance().getReference("Users")

                val firstName = it.child("firstName").value
                val lastName = it.child("lastName").value
                val position = it.child("position").value
                val email = it.child("email").value

                tv_Imie.text = firstName.toString()
                tv_Nazwisko.text = lastName.toString()
                tv_Stanowisko.text = position.toString()
                tv_Email.text = email.toString()
                Toast.makeText(this, "User does not exist", Toast.LENGTH_SHORT).show()
            Toast.makeText(this, "Failed", Toast.LENGTH_SHORT).show()

            Log.e("firebase", "Error getting data", it)

Here is my database structure

I checked some ways to solve this problem.

I have seen some people propose a solution with addValueEventListener, but then the list is fetched. I want single user information to be included in my textViews. I read that the problem may be related to a bug in Firebase and not in the code.

Ok, problem was with Firebase not my application. I don't know why but when I started app in every try Firebase closed my connection with database. I tried add to google.services.json some links to database and change some settings but this didn't work. After all I removed app from firebase and delete file google.services.json. I added app again on website then I connect app with firebase and new google.services.json was set. That's all everything is working thanks for help.
