Sending non-protected broadcast using Intent Wedge

Tobia_Scapin · October 23, 2025, 8:18pm

Hello.
I’m trying to get a Memor 12 scan result using Intent Wedge.
I enabled the Intent Wedge and added a custom Intent action settings.

When I scan, logcat reveal this exception:

Sending non-protected broadcast com.myapp.ACTION from system 7218:com.datalogic.service/1000 pkg com.datalogic.service (Ask Gemini)
	java.lang.Throwable
		at com.android.server.am.ActivityManagerService.checkBroadcastFromSystem(ActivityManagerService.java:13824)

I’m using a runtime BroadcastReceiver with the correct IntentFilter.

Hello again @Tobia_Scapin,

The message you are seeing in logcat is because we are sending a broadcast without defining a required permission. This is not an error but a warning, intended to inform the developers of com.datalogic.service that they should restrict their broadcast with a permission. To maximize compatibility, we do not intend to change intent wedge to use a protected broadcast. So, as a result of this decision, you will continue to see these messages in logcat.

However, the most likely cause of your issue is to do with the category of the intent. There are two ways you can ensure the category of your broadcast is set correctly.

Entirely remove the category from Datalogic setting and disable the WEDGE_INTENT_EXCLUDE_EMPTY_VALUES
Or include the category in your intent filter, the default of which is com.datalogic.decodewedge.decode_category

I will also say, it looks like you have changed the action to com.myapp.ACTION, it can be easier to just leave it as com.datalogic.decodewedge.decode_action since it will just be one less setting to change.

hi i have the same issue, code below memor 30, any assistance greatly appriciated.

using Android.Content;

            _resultText.Text = $"HandleIntent: {intent?.Action }\n";

            if (intent?.Action == "com.datalogic.decodewedge.decode_action")
            {
                string barcodeString = intent.GetStringExtra("com.datalogic.decode.intentwedge.barcode_string");
                string barcodeType = intent.GetStringExtra("com.datalogic.decode.intentwedge.barcode_type");
                string barcodeData = intent.GetStringExtra("com.datalogic.decode.intentwedge.barcode_data");

                if (!string.IsNullOrEmpty(barcodeData))

                    });
                }
            }

As I said before, seeing this is not an issue and is not something we are going to change.
This has no impact on your ability to utilize the barcode data Intent Wedge.
What behavior is not meeting your expectation?

Hi
In the log you’ll see an exception, my test app isn’t receiving the data, if there is something i have not done correctly please let me know (a setting on the device, my intent filter).

11-13 11:52:37.433 E/ActivityManager( 1981): Sending non-protected broadcast com.datalogic.decodewedge.decode_action from system 3291:com.datalogic.service/1000 pkg com.datalogic.service

Hello @matt_daniel,

If you look above your message I answer it in detail.

It sounds like you need a support agent to discuss the issue with directly.

Hello @matt_daniel

I think the app isn’t receiving the barcode data because of a mismatch between how Decode Wedge sends the intent and how the code receives it.

in your code you use:

An [IntentFilter] attribute on the Activity
OnNewIntent() method to handle intents

This approach works ONLY if Decode Wedge is configured to use START_ACTIVITY mode.

However, in your case Memor 30’s Decode Wedge is configured to send BROADCAST intents (as you can see from the log message “Sending non-protected broadcast…”).

The difference is that while with START_ACTIVITY the Intent is delivered directly to an Activity (explicit intent) → triggers OnNewIntent(), with BROADCAST, the Intent is sent as a broadcast (implicit intent) and requires a BroadcastReceiver to intercept it.

As a result the IntentFilter attribute and OnNewIntent() method are never triggered by implicit broadcast intents.

The solution I would suggest is to create and register a BroadcastReceiver dynamically in code.

Code sample:

protected override void OnCreate(Bundle savedInstanceState)
{
      ...
      // BroadcastReceiver registration
      var filter = new IntentFilter("com.datalogic.decodewedge.decode_action");
      filter.AddCategory("com.datalogic.decodewedge.decode_category");
      RegisterReceiver(new DecodeReceiver(), filter);
}

// Receiver
public class DecodeReceiver : BroadcastReceiver
{
    public override void OnReceive(Context ctx, Intent i)
    {
        var data = i.GetStringExtra("com.datalogic.decode.intentwedge.barcode_string");
        var type = i.GetStringExtra("com.datalogic.decode.intentwedge.barcode_type");
    }
}
