I think you should set a boolean state for page1 in service. when the page1 Activity_Pause it is false, else true.

This is not right for me.

You can define a global variable IscurrentPage2 for page2 in code or service module. you can set the value is true when page2 is create or resume event, false is in pause event.

You can use the code to judge if page2 is current page

B4X:

if yourmodule.IscurrentPage2 then
    connect database
    else
    disconnect
endif

Also use this to get TopPage

B4X:

Dim TopPage As String = B4XPages.GetManager.GetTopPage.Id
