How shell a app?
i have a APP1 and other: APP2, i need shell APP1 from APP2 .

The next quesition was: pass user from app1 to app2 (and no login in app2, because the user are login in app1)

i try to punt:

Sub cmdHerramientas_Click
    Dim i As Intent
    
    
    
    Try
'    i.Initialize("","")
'        Dim jo As JavaObject = i
'        jo.RunMethod("setPackage", Array("netsistemas.fricaltecgases"))

        i.Initialize(i.ACTION_VIEW  ,"")
        i.SetPackage("perico.app2")

        i.SetType("*/*")
        StartActivity(i)
    Catch
        Log(LastException)
        Msgbox(LastException.Message,"")
    End Try

End Sub

and in manifest app2 (perico.app2)

AddActivityText(main,
<intent-filter>
              <action android:name="android.intent.action.VIEW" />
</intent-filter>
)

Thanks a little step is ok, but.
why mi app called (app1) are finisth. The 'treadh' are acupped by app2.
how get the 2 applications opened?

And.
To pass param i do this:
In app1:

...

    returnIntent.PutExtra("Settings","username")

...

and in app2:

Sub Activity_Create(FirstTime As Boolean)
 

    Dim pm As B4XPagesManager
    pm.Initialize(Activity)
    
    Dim in As Intent

    in = Activity.GetStartingIntent
    If in <> Null Then
        MsgboxAsync(in.HasExtra("GetSettings"),"")
    End If

    
End Sub




but the app2 say blank (empty text)

Yóu can´t! Only one activity can run at a time. You can send a intent to start the other.

Oh!,
Then, the user must open and insert againg user in app2.
My idea is get 2 apps, and lunch the second in other 'thread' and then, the user change between one an other..
App1 is B4Android, new app2 is B4X (or migrate all to App2... no... 2 apps and finish question).
Thansk all.

and the second question? pass param to app2 (for to learn how do this).

Why would you need two Apps? What stops you combining the logic etc into a single unit?

One very beeg for re-doit, the other with b4xpages, and a don't want change app1 (run app? yes? don't touch)
