Android Question Handle multiple permission request

I have in my app multiple permission requests, such as:
rp.CheckAndRequest(rp.PERMISSION_READ_CONTACTS)
rp.CheckAndRequest(rp.PERMISSION_READ_CALL_LOG)
rp.CheckAndRequest(rp.PERMISSION_CALL_PHONE)

I wish that app will start only if the above will approve (since no point opening the app without it)
what is the best way to handle such

You could possibly use this:

B4X:
Sub Activity_PermissionResult (Permission As String, Result As Boolean)
   If Permission = rp.PERMISSION_ACCESS_FINE_LOCATION Then
     gmap.MyLocationEnabled = Result
   ELSE
        ' Credit for the following code to DonManfred
         rs= Msgbox2("You have not given permission - I can not proceed"    ,"Permission Failure","Yes","Cancel","No",Null)
        If rs=DialogResponse.POSITIVE Then
             StopService(Starter)
            Activity.Finish
            ExitApplication
            Return True ' RETURN TRUE to consume the Event---
   End If
End Sub
Example discussion here https://www.b4x.com/android/forum/threads/app-not-closing.92401/#post-584361

I have not tested - but I have faith that it will work.

Enjoy !!

Multiple If Statements.

Process --> Check and Request --> Permission Result --> If statement --> Return --> Check next permission --> Repeat Process.

Let's presume you have 3 permissions.

Check the first one - user accepts - so it's OK

Check the second one - user accepts - so it's OK

Check the third one - user does NOT accept - so app does not execute.

Enjoy !!

Edit: don't put this code in Activity_Resume. Request the permissions right before you need them.
Activity_Resume can be called multiple times during the requests and it can cause some requests to fail.

B4X:
Sub Activity_Resume
   For Each permission As String In Array(rp.PERMISSION_READ_CONTACTS, rp.PERMISSION_READ_CALL_LOG, rp.PERMISSION_CALL_PHONE)
       rp.CheckAndRequest(permission)
       Wait For Activity_PermissionResult (permission As String, Result As Boolean)
       If Result = False Then
           ToastMessageShow("No permission!", True)
           Activity.Finish
           Return
       End If
   Next
   'we have permission!
End Sub
