Android Question How to send parameters from App_A to App_B2?

[Theera]

Hi all,
I've studied SD_TreeList as App_A and SDShopListView as App_B in the examples. I would like to use intent library and send the left sub in App1 to be the filter parameter.
How do I code when I click the left sub ?

from example2 I have coded my App_A like this,it's correct ,or not,Sir? I'm sorry for English,if you don't understand. I would like to send LeftName to App_B,after I clicked the left node.

Private Sub B4XTree1_Click (IDLeaf As String, LeafName As String)
'ToastMessageShow($"ID Leaf:${IDLeaf} LeafName:${LeafName}"$,True)
Dim in As Intent
in = Activity.GetStartingIntent
If in <> Null Then
If in.HasExtra("GetSettings") Then
in.Initialize(in.ACTION_MAIN,"")
in.SetPackage("b4a.requester") ' sent parameter to b4a.requester app (ShopListview app)
in.SetType("text/plain")
in.PutExtra("android.intent.extra.TEXT",LeafName)
in.Action=in.ACTION_SEND
StartActivity(in)
Activity.Finish
End If
End If

End Sub

Incorrect: GetStartingIntent must be inside the receiver app.

I modified your examples above as sd_treelist example send intent to shoplistview example.
check in these examples:-
1- manifest file of shoplistview (receiving intent)
2- check the shoplistview packagename is changed to be the same that sd_treelist example want to send intent to it.

check attachments (note in shoplistview example i comment 0.jpg,.... etc because i don't have)
