I'd like to connect a German Macintosh keyboard to my Android device. It uses swapped signals for °/^ and </> as well as different positions for [, ], {, } and @. It also has a bunch of special characters, but I don't consider those of high priority.
I tested More Physical Keyboard Layouts, but it doesn't feature Macintosh layouts (yet). I also saw the External Keyboard Helper Pro that allows to define a custom layout, but it requires a Google Account to buy it from the Play Store, but I need a solution that works with AOSP.
(Free apps on the Play Store are fine, because I can download those anonymously using the Aurora Store.)
