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)
		at com.android.server.am.ActivityManagerService.broadcastIntentLocked(ActivityManagerService.java:14546)

		at android.os.Binder.execTransactInternal(Binder.java:1280)
		at android.os.Binder.execTransact(Binder.java:1244)

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.

using Android.Content;
using playAndroid;

namespace DatalogicScannerDemo
{
    [Activity(Label = "Datalogic Scanner Demo", MainLauncher = true)]
    //[IntentFilter(new[] { "com.datalogic.decodewedge.decode_action" })]
    [IntentFilter(
        new[] { "com.datalogic.decodewedge.decode_action" },
        Categories = new[] {
            Intent.CategoryDefault,
            "com.datalogic.decodewedge.decode_category"
        })]
    public class MainActivity : Activity
    {
        TextView _resultText;
        
        protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
            SetContentView(Resource.Layout.activity_main);
            //SetContentView(DatalogicScannerDemo.Resource.Layout.activity_main);


            _resultText = FindViewById<TextView>(Resource.Id.resultText);
            _resultText.Text = "Scan a barcode...";
        }
        
        protected override void OnNewIntent(Intent intent)
        {
            _resultText.Text = "OnNewIntent \n";
            base.OnNewIntent(intent);
            HandleIntent(intent);
        }
        
        private void HandleIntent(Intent intent)
        {
            _resultText.Text = "HandleIntent \n";
            _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))
                {

                        _resultText.Text = $"Scanned: {barcodeData}\nType: {barcodeType}\nData: {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).
