mGoogleSignInClient = GoogleSignIn.getClient(this,gso)

this is my code

class LogInActivity : AppCompatActivity() {

lateinit var mAuth : FirebaseAuth

lateinit var mGoogleSignInClient: GoogleSignInClient
lateinit var gso: GoogleSignInOptions
val RC_SIGN_IN : Int =1

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_log_in)
    FirebaseApp.initializeApp(this)
    val SignInBT = findViewById<View>(R.id.Sign_BT) as SignInButton
    mAuth= FirebaseAuth.getInstance()
    gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        .requestIdToken("724129725157-qu45prsbotdtsonbvolm3d2tn99sg84t.apps.googleusercontent.com")
        .requestEmail()
        .build()

    mGoogleSignInClient = GoogleSignIn.getClient(this,gso)

    SignInBT.setOnClickListener {

            view: View? ->  Signingoogle()

    }

    login_BT.setOnClickListener {
        AllowingUserToLogin()
    }

}

override fun onStart() {
    super.onStart()

    val currentUser = mAuth!!.getCurrentUser()

    if (currentUser != null){

        SendToRegister()

    }
}

private fun AllowingUserToLogin() {

    var email: String = email_ET.text.toString()
    var password : String = password_ET.text.toString()

    when {
        email.isEmpty() -> Toast.makeText(this,"ادخل الايميل", Toast.LENGTH_LONG).show()
        password.isEmpty() -> Toast.makeText(this,"ادخل كلمة المرور", Toast.LENGTH_LONG).show()
        else -> mAuth.signInWithEmailAndPassword(email,password)
            .addOnCompleteListener { task ->

                if (task.isSuccessful){

                    SendUserToMain()

                }else {

                    Toast.makeText(this, "الايميل وكلمة المرور غير متطابقة", Toast.LENGTH_LONG).show()

                }

            }
    }
}

private fun SendUserToMain() {
    var i = Intent(this,MainActivityC::class.java)
    startActivity(i)
}

private fun SendToRegister(){
    var i = Intent(this , RegesterActivity::class.java)
    startActivity(i)

}
private fun Signingoogle() {
    val sigInIntent: Intent = mGoogleSignInClient.signInIntent
    startActivityForResult(sigInIntent,RC_SIGN_IN)

}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)

    if(requestCode == RC_SIGN_IN){
        val task : Task<GoogleSignInAccount> = GoogleSignIn.getSignedInAccountFromIntent(data)
        handleResult(task)
    }
}

private fun handleResult(task: Task<GoogleSignInAccount>) {

    try {
        val account : GoogleSignInAccount =task.getResult(ApiException::class.java)
        updateUI(account)
    }catch (e: ApiException){
        Toast.makeText(this,e.toString(), Toast.LENGTH_LONG).show()
    }
}

private fun updateUI(account: GoogleSignInAccount){

    var name = account.displayName.toString()
    var email = account.email.toString()
    var password = "123456"
    mAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener { task ->

        if(task.isSuccessful){
            SendToRegister()
        }else {
            Toast.makeText(this,"خطأ في التسجيل", Toast.LENGTH_LONG).show()}
    }

}

}

and this is my gradle dependencies

    implementation fileTree(dir: 'libs', include: ['*.jar'])

} apply plugin: 'com.google.gms.google-services'

the problem is with your this argument which you are passing to the GoogleSignIn.getClient() method. probably because you are missing the client.

try adding this com.google.android.gms:play-services-base:12.1.0 this dependency will provide the client. 在此处输入图片说明
