Android Question Help: My B4A app is not receiving DataWedge intents on Android 13

[fabton1963]

Hi everyone,
I’m having trouble getting my B4A app to receive intents sent from DataWedge (or via adb broadcast) on Android 13.
Here’s my manifest

AddManifestText(
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="35"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.

' Receiver export (ok anche su Android 11)
SetReceiverAttribute(zebrareceiver, android:exported, "true")

' Filtro per DataWedge: action DEVE combaciare con il profilo
AddReceiverText(zebrareceiver,
<intent-filter>
    <action android:name="com.elmac.DTWEDGE" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>
)

Starter service

Sub Process_Globals
    Public PendingScans As List
End Sub

Sub Service_Create
    PendingScans.Initialize
End Sub

Public Sub OnScanFromDW(code As String)
    If SubExists(B4XPages.MainPage, "read_item_barcode") Then
        CallSubDelayed2(B4XPages.MainPage, "read_item_barcode", code)
    Else
        PendingScans.Add(code)
    End If
End Sub

zebrareceiver.bas

Sub Receiver_Receive (Intent As Intent)
    Log("DW action: " & Intent.Action)
    Log("DW extras: " & Intent.ExtrasToString)

    Dim code As String
    If Intent.HasExtra("com.symbol.datawedge.data_string") Then
        code = Intent.GetExtra("com.symbol.datawedge.data_string")
    Else If Intent.HasExtra("com.motorolasolutions.emdk.datawedge.data_string") Then
        code = Intent.GetExtra("com.motorolasolutions.emdk.datawedge.data_string")
    Else
        Return
    End If

    CallSubDelayed2(Starter, "OnScanFromDW", code)
End Sub

What happens​

I’ve confirmed that my app’s receiver is correctly listed when I run:
adb shell cmd package dump com.elmac.zebrascan
and it shows:

Receiver Resolver Table:
Action: "com.elmac.DTWEDGE"
Category: "android.intent.category.DEFAULT"

However, when I send this broadcast:

adb shell am broadcast -a com.elmac.DTWEDGE -c android.intent.category.DEFAULT --es com.symbol.datawedge.data_string "TEST123"

nothing happens — my Receiver_Receive sub never fires and no log messages appear.

My questions​

1. Is there something I’m missing in the manifest for implicit broadcasts on Android 13+?
2. Do I need to register the receiver dynamically (e.g., via BroadcastReceiver.Initialize in a service) instead of statically in the manifest?
3. Has anyone successfully received DataWedge broadcasts with B4A targeting SDK 33+?

Any help, sample project, or working manifest would be greatly appreciated

Thanks in advance!

Something happens:
java.lang.Exception: Sub receiver_receive signature does not match expected signature.

public static anywheresoftware.b4a.pc.RemoteObject com.elmac.zebrascan.zebrareceiver_subs_0._receiver_receive(anywheresoftware.b4a.pc.RemoteObject) throws java.lang.Exception

SOLVED:

Private Sub Receiver_Receive [B](FirstTime As Boolean, StartingIntent As Intent)[/B]
    Log("DW action: " & StartingIntent.Action)
    Log("DW extras: " & StartingIntent.ExtrasToString)

    Dim code As String
    If StartingIntent.HasExtra("com.symbol.datawedge.data_string") Then
        code = StartingIntent.GetExtra("com.symbol.datawedge.data_string")
    Else If StartingIntent.HasExtra("com.motorolasolutions.emdk.datawedge.data_string") Then
        code = StartingIntent.GetExtra("com.motorolasolutions.emdk.datawedge.data_string")
    Else
        Return
    End If

    ' Non dare per scontato che Starter sia già attivo:
    CallSubDelayed2(Starter, "OnScanFromDW", code)
End Sub
