Open Another Form LAMW Android

[spacepascal]

I changed PC and i reinstalled LAWM in a new PC. Usually i used this code to Open Another form, but for somewhat reason is not working anyway. Also in the past i had some trouble to open the others forms but i resolved the issue with this code, especially with the "close;" line.

Code: Pascal  [Select][+][-]

1.    if AndroidModule2 = nil then
2.      begin
3.        gApp.CreateForm(TAndroidModule2, AndroidModule2);
4.        AndroidModule2.InitShowing();
5.      end;
6.     Close;

Right now this code don't work anymore. Why? There is a single place where to learn lamw programming?

I tested the code in Android 14
Thanks to all the heros who want to help me!!

My code to create the form, and force to the front, I am using Android 14.:

Code: Pascal  [Select][+][-]

1.       if (AndroidModule2 = nil) then
2.         begin
3.           gapp.CreateForm(TAndroidModule2, AndroidModule2);
4.           AndroidModule2.Init();
5.           AndroidModule2.MoveTaskToFront();
6.         end;

Code to show the form:

Code: Pascal  [Select][+][-]

1.    AndroidModule2.Show;    

I also have the second form in the uses clause of the controls.lpr
The MoveTaskToFront can probably be put just before the show, not sure why I put it there, I must have had a reason

I don't know why but don't work for me. There are some changes in LAMW in the form initialization?

What does happen? Do you have error or crash?

This is code from one of my test apps, it is similar to c4p's code:

Code: Pascal  [Select][+][-]

1. procedure TAndroidModule1.AndroidModule1ActivityCreate(Sender: TObject; intentData: jObject);
2. begin
3.   If AndroidModule2 = nil then
4.   begin
5.     gApp.CreateForm(TAndroidModule2, AndroidModule2);
6.     AndroidModule2.DoJNIPromptOnInit := False;
7.     AndroidModule2.BackgroundColor := colbrGhostWhite;
8.     AndroidModule2.Init;
9.   end;
10. end;
11.  
12. procedure TAndroidModule1.btnForm2Click(Sender: TObject);
13. begin
14.   AndroidModule2.Show;
15. end;

This last example seem to work well, why the others don't work? No error nor others issues. Strange behavior maybe there was an update in LAMW Form initialization i don't know.

Difference between c4p's and mine example is that I explicitly set form's background color - backgrounds in Android are transparent by default.

That is the reason I asked what does happen exactly. I.e.: nothing is shown, a crash, overlapping of elements from first and second form, ...

100% correct, I have my Background on the second form set to Black / coblBlack.
Transparency by default causes so many issues.
