Android Question Login against WS best practice?

[leitor79]

Hello,

My app has to login against a webservice. So, I show the user a dialog where the username and passwords are input and then call the webservice.

The question is; what would be the best approach to follow when the login fail and the credentials should be asked again? I'm not comfortable with putting the logic into a loop. This is my code.

Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, 350dip, 350dip) 'set the content size
    p.LoadLayout("layLogin")
    Dim rs As ResumableSub = Dialog.Show(Activity, p, "Login", "", "Cancelar")
    
    Wait For (rs) Complete (Result As Int)
    If Result = xui.DialogResponse_Positive Then

        CallSubDelayed3(sWS, "Login", txtNombre.Text, txtClave.text)
        
    End If

sWS is a service module, and this code is located at the Main module.


Regards!

You can call this sub again.

Thanks, Erel. Is there a way to keep the dialog opened during the login process?

Thank you!

You can remove the built-in buttons and add your own buttons. This will allow you to do whatever you need and then close the dialog from your code.

You can also use B4XDialog which is completely customizable: https://www.b4x.com/android/forum/threads/b4x-xui-b4xdialog-custom-dialogs.99756/#content

Thank you very much!
But, I'm already using the b4xdialog... but I see what you meant.
