I'm looking for a solution to these problems:
1) How to change Android Keyboard language?
2) How to detect all installed keyboard languages?
3) How to install some keyboard language?
Are these problems possible to do? I found some info:
Ad 1) I think this is not possible right (without permission and app has to run as a system app)? Source: Change Keyboard input language
Ad 2) I can detect current language (How to programmatically get current keyboard language on an Android device) but I want to detect all installed languages. Is it possible?
Ad 3) Is this possible? Or only the user can do it? The best way what I found is open language settings with intent.
Can someone please confirm that.
