如何在 Android 8.1 真机上运行应用

如何解决如何在 Android 8.1 真机上运行应用

我使用 Xamarin.Android 开发了 android 应用程序，它在 Android 8.1 - API27 模拟器上完美运行。当我尝试在 Newland MT9052 终端的真实设备上运行时，应用程序总是填写 FailureListener。

当我在调试模式下运行应用程序时，虽然电子邮件和密码正确，但应用程序填写到FailureListener。

这是我的 LoginActivity.cs：

TextInputLayout emailText;
        TextInputLayout passwordText;
        Button girisYapButton;
        TextView txtViewUyeOl;
        LinearLayout linearLayout;
        FirebaseAuth mAuth;
        TaskCompletionListener listener = new TaskCompletionListener();

       
        protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
            SetContentView(Resource.Layout.activity_login);
            // Create your application here
            emailText = (TextInputLayout)FindViewById(Resource.Id.textEmailLogin);
            passwordText = (TextInputLayout)FindViewById(Resource.Id.textSifreLogin);
            linearLayout = (LinearLayout)FindViewById(Resource.Id.linearLayout);

            girisYapButton = (Button)FindViewById(Resource.Id.buttonGirisYap);
            girisYapButton.Click += GirisYapButton_Click;

            Initializefirebase();
            
            txtViewUyeOl = (TextView)FindViewById(Resource.Id.textViewUyeOl);
            txtViewUyeOl.Click += txtViewUyeOl_Click;
        }

        private void GirisYapButton_Click(object sender,EventArgs e)
        {
            string email,password;

            email = emailText.EditText.Text;
            password = passwordText.EditText.Text;

            if (!email.Contains("@"))
            {
                new Android.Support.V7.App.AlertDialog.Builder(this)
                    .SetPositiveButton("Tamam",(sender,args) =>
                    {

                    })
                    .SetMessage("Lütfen geçerli bir e-mail adresi giriniz!")
                    .SetTitle("Uyarı")
                    .Show();
                return;
            }
            else if(password.Length < 6)
            {
                new Android.Support.V7.App.AlertDialog.Builder(this)
                    .SetPositiveButton("Tamam",args) =>
                    {

                    })
                    .SetMessage("Lütfen en az 6 karakterli şifrenizi giriniz!")
                    .SetTitle("Uyarı")
                    .Show();
                return;
            }
            else
            {
                listener.Success += Listener_Success;
                listener.Failure += Listener_Failure;
                mAuth.SignInWithEmailAndPassword(email,password)
                    .AddOnSuccessListener(this,listener)
                    .AddOnFailureListener(this,listener);
                
            }

        }

        private void Listener_Failure(object sender,EventArgs e)
        {
            Snackbar.Make(linearLayout,"Email veya şifreniz yanlış!",Snackbar.LengthShort).Show();
        }

        private void Listener_Success(object sender,EventArgs e)
        {
            StartActivity(typeof(MainActivity));
        }

        void Initializefirebase()
        {
            var app = FirebaseApp.InitializeApp(this);

            if (app == null)
            {
                var options = new FirebaSEOptions.Builder()
                    .SetApplicationId("konumbulapp-1fc67")
                    .SetApiKey("AIzaSyA5yRMMJ8ztcdWbIcmOxLyY6Xl_xkDxWzI")
                    .SetDatabaseUrl("https://konumbulapp-1fc67-default-rtdb.firebaseio.com")
                    .SetStorageBucket("konumbulapp-1fc67.appspot.com")
                    .Build();

                app = FirebaseApp.InitializeApp(this,options);
                mAuth = FirebaseAuth.Instance;
                
            }
            else
            {
                mAuth = FirebaseAuth.Instance;
            }
        }

这是我的 TaskCompletionListener.cs：

public class TaskCompletionListener : java.lang.Object,IOnSuccessListener,IOnFailureListener
    {
        public event EventHandler Success;
        public event EventHandler Failure;

        public void OnSuccess(java.lang.Object result)
        {
            Success.Invoke(this,new EventArgs());
        }

        public void OnFailure(java.lang.Exception e)
        {
            Failure.Invoke(this,new EventArgs());
        }
    }

This my Application properties

This my Android Manifest

我不知道我做错了什么或错过了什么。

当我构建应用程序时，我没有收到错误。
