Hi Dan.

I see that you also filed a Help Desk ticket about this topic.

I think this TechDoc may also contribute to this topic:

https://techdocs.zebra.com/datawedge/13-0/guide/api/enabledatawedge/

Are you sure that you want to DISABLE Datawedge for all users/app of the device? 

Or just disable the Scanning for a specific function within your application?

Also what do you get with this:

https://techdocs.zebra.com/datawedge/13-0/guide/api/resultinfo/

Two things:  ( NOTE I am using Android Studio sample code from the TechDoc )

Do just this first:

Intent i = new Intent();
i.setAction("com.symbol.datawedge.api.ACTION");
i.putExtra("com.symbol.datawedge.api.ENABLE_DATAWEDGE", false);
this.sendBroadcast(i);

Then the extra next:  ( Please Read the TechDoc I listed for you - it seems you are layering in too many things in your intent.apply{} )

// request and identify the result code
    i.putExtra("SEND_RESULT","true");
    i.putExtra("COMMAND_IDENTIFIER","123456789");
    this.sendBroadcast(i);

Try the following Manually before you run your test:

Goto the Datawedge app.

Once in the app - goto the 3-dot menu and Settings.

Tap the "Datawedge enabled" munu line to "uncheck" the menu.

( NOTE: This is disabling Datawedge - which is what your code above is attempting to enable )

Click back once.  Click Home button and then choose Recent apps menu and right-swipe Datawedge to fully close the UI.

Then test: and see if you get the confirm that Datawedge is started.  ( Then you can lso go back into Datawedge and check the menu that you had "disabled".
