Sir, i am developting a ble keyboard hardware for my Mobile.
My Mobile connects to this ble keyboard hardware and i have a HID device.
It´s working very nice, when i press a key on the ble keyboard hardware, for example A,B,C.., in can see them on APPINVENTOR APP if APPINVENTOR virtual keyboard is open on screen.
But imagine one case study where an APPINVENTOR APP screen not shows the virtual keyboard and you press a key on the ble keyboard hardware, in theory you will loose that key right ?
Well, i dont want to loose that key, i want that APPINVENTOR APP know about that key pressed and do something, being the main APP or not ?
Think about a Situation that the APPINVENTOR APP is running in background, you open any other APP and you press a sequence key A,A,A,B on ble keyboard hardware, your APPINVENTOR APP must to detect too that sequence.
I guess, that there is a option to capture the ANDROID O.S EVENTS, too see all that is travelling, something like this
About Messages and Message Queues - Win32 apps | Microsoft Docs
Do you undestand ?
I can send one of these multiples sequences! But the APPINVENTOR must to detect one, regardless of being the main app running
