Android Question [RESOLVED] SDK 34, Broadcast Receiver, Unable to start.

Jmu5667 · Jul 17, 2024

Hello

I will try to be very specific in relation to this issue. I have a service, svc_br_receiver, and in that service I use broadcast receiver lib. The lib has a method called registerReceiver. Under SDK 34 it fails with the following:

B4X:

svc_br_receiver_service_create (java line: 300)

I have looked this up on the web and found the following; https://stackoverflow.com/questions...r-not-exported-should-be-specified-when-a-rec

I do not know if the lib is supported anymore https://www.b4x.com/android/help/broadcastreceiver.html

The intents I need to receive dont work when they are in the manifest (static) only in a service(dynamic). There are no background services, notifications etc, just intent receiving.

Suggestions ?

Regards

John.

You are asking about this library: https://www.b4x.com/android/forum/threads/broadcastreceiver.12493/#content

Use this sub to register the receiver instead of calling br.RegisterReceiver:

B4X:

Private Sub RegisterReceiver(br As BroadCastReceiver, Exported As Boolean)
    Dim p As Phone
    If p.SdkVersion < 33 Then
        br.registerReceiver("")
    Else
        Dim r As Reflector
        r.Target = br
        Dim filter As Object = r.GetField("filter")
        Dim receiver As Object = r.GetField("receiver")
        Dim ctxt As JavaObject
        ctxt.InitializeContext
        ctxt.RunMethod("registerReceiver", Array(receiver, filter, IIf(Exported, 2, 4)))
        r.SetField("isRegistered", "true", "java.lang.boolean")
    End If...

        r.SetField("isRegistered", "true", "java.lang.boolean")
    End If
End Sub

Depends on Phone, Reflection, JavaObject libraries.
Note that I haven't fully tested it.

To unregister the receiver with SDK34

B4X:

Sub unRegisterReceiver(pBR As BroadCastReceiver)

    Dim p As Phone
    If p.SdkVersion < 33 Then
        pBR.unregisterReceiver
    Else
        Dim r As Reflector
        r.Target = pBR
        Dim receiver As Object = r.GetField("receiver")
        Dim ctxt As JavaObject
        ctxt.InitializeContext
        ctxt.RunMethod("unregisterReceiver", Array(receiver))
        r.SetField("isRegistered", "false", "java.lang.boolean")
    End If
End Sub

I think that the regular BR.unregisterReceiver will also work. No need for special code.

I had that in code already and it failed with receiver not register, so I used unRegisterReceiver without any issues. Thanks for your help on this one.
