LAMW : question about back button

Hi

I have a main AndroidModule "A" with ActivityMode=actMain, and
secondary modules "B" and "C"  with ActivityMode=actRecyclable

From A, I create and init B if necessary, and show it.

If I touch the back button when B is displayed, it is closed and A is
displayed. This is what I expect.

From B,  I create and init C if necessary, I show it and close B. C is
displayed as expected.

But, if I touch the back button when C is displayed, the application
is closed. I'd like to display A...

If I touch a button on C, running a Close, the A module is displayed
as expected.


How can I have the back button always going back to the main module ?

Thanks

you need:  AndroidModuleXX.TryBacktrackOnClose:= True;    //
<<-------- 

use example:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i    
gApp.CreateForm(TAndroidModuleXX, AndroidModuleXX);   
AndroidModuleXX.TryBacktrackOnClose:= True;    // <<--------     
AndroidModuleXX.Init(gApp); 
you can see the demo "AppTest1", too.
