Here is the manifest :-
AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<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.

'PER ANDROID THINGS
AddApplicationText(<uses-library android:name="com.google.android.things"/>)

''Launch activity automatically on boot (can remove if not needed)
AddActivityText(Main,
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.HOME"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
)
AddPermission(com.google.android.things.permission.USE_PERIPHERAL_IO)
AddPermission(com.google.android.things.permission.MANAGE_INPUT_DRIVERS)

As you can see I added the permission for the USE_PERIPHERAL_IO - so what is going on ?

Note I also ensured the instruction are uptodate using v1.10, I'm using B4A v10.0 - and the Android thing v1.0.14

can anyone help ?
