iOS Question Merge two apps in B4i

[Tecnoswitch]

Good morning,
can someone help me to solve my problem?
In B4A I used StartActivity() to link two different App, but in B4i there isn't StartActivity().
What method or instruction should I use to merge the two apps?
Thanks a lot
Vincenzo

The question is how to start a second app. The answer is:

Target app:
Add to main module:

#UrlScheme: b4i.example2

Source app:

#QueriesSchemes: b4i.example2

Private Sub Button1_Click
    If Main.App.CanOpenURL("b4i.example2://") Then
        Main.App.OpenURL("b4i.example2://")
    End If
End Sub

Hi Erel,
I tried with your solution but it doesn't work.
I have two modules (Main and Main_2 associated with the two apps).

In Main:

#UrlScheme: Main_2

#QueriesSchemes: Main

Private Sub Button1_Click
If Main_2.App.CanOpenURL("Main://") Then
Main_2.App.OpenURL("Main://")
End If
End Sub

In Main_2:

#UrlScheme: Main

#QueriesSchemes: Main_2

Private Sub Button2_Click
If Main.App.CanOpenURL("Main_2//") Then
Main.App.OpenURL("Main_2//")
End If
End Sub

I have made some errors?
Thank you so much for your help.

You should be using the Package ID which is defined in Project->Build Configurations for this not the function name.

So App1, the package id is b4i.example
App2 the package id is b4i.example2.

This is what is used from App1 to start App2.

Please use [code]code here...[/code] tags when posting code.
There are several mistakes in your code. Carefully see my example.

I'm trying but no results.
I used the package ID instead of the module name, leaving the two apps separate, as suggested but nothing.
I am not an expert.
I don't use the Main function, it must be declared, how?
Help me
Thanks

Here is a sample project which create 2 apps which will be an example.

How to use:

Stage 1
Set the build configuration to callee

Use Tools->Build Server -> Build release app

The Callee app should be installed on your device.

Stage 2
Set the build configuration to calling

Compile.

When run you can click on the button which will start the Callee app.

Hi Andrew,
thank you so much for your answer.
My version of the B4i does not have the CALLEE and CALLING functions...
How can I do?

Off topic, If you are using B4i you should appear as Licensed User in the forum, how come you don't have a tag?

Caller and callee are Build configurations which allow me to create 2 apps from one source code.

see this:

Conditional Compilation & Build Configurations

B4A v3.80 adds support for conditional compilation. From Wikipedia: In computer programming, conditional compilation is compilation implementing methods which allow the compiler to produce differences in the executable produced controlled by parameters that are provided during compilation...

www.b4x.com

Build configurations are available in all IDE's.
