Android Question Delay and Blank screen after calling CallSubDelayed connecting 2 activities

[shank_devdroid]

Dear Members,

Please help I am switching from a LogIn screen(Main Activity) to a 2nd activity having a lot of panels,layout and images.
As soon as I call the CallSubDelayed Method fter successful Login details there is a delay and a blank screen appears, after a delay of about 4-5 seconds the 2nd activity is created and the respective screen appears.

Please find the code below and screenshots of the same.

If enteredPassword = masterPassword Then
                Log("login successful")
                Msgbox("Login Successful", "HURRAY!!!")
                resetAllPassword
                CallSubDelayed(Automation, "Activity_Create")               
'                StartActivity(Automation)
                               
            Else
                Log("Wrong password!!")
                Msgbox("Wrong Password!! Please enter again!", "OOPSS!!")

Also I tried using StartActivity too but this also gives the same problem.

The code for another activity-Automation

    'Activity.LoadLayout("Room_Change")

Have you tested it in release mode?

I don't know if it is related or not however the socket code looks wrong. Sockets should not be tied to the activity life cycle. Either move it to the Starter service or initialize it only when FirstTime is true.

Thanks for the reply Erel.

Yes I have tested in the release mode and there is 4-5 sec delay when switching to the 2nd Activity.

I will move the socket initialization in the Started service and check again!
Do you think any other issue/problem can be the reason for this delay?

Regards!

 

[Erel]

Do you really need to load all these layouts when the activity is created? This is the cause for the delay.

Load only the layout that you need to show the activity. Load other layouts later when they are needed.

Thank you so much Erel for this information,

Well I will check and load the other layouts in the respective subs.
Only the main layout will be called during Activity_Create Sub.

If I come across any issue, I will post it here.

Really Thanks
