I want to develop my own on-screen keyboard for Android. This keyboard should be the only selectable keyboard on the Android device.
I was able to create the keyboard, but something is still missing. I can't disable the AOSP keyboard. This is possible with some keyboards from other developers, such as SwiftKey
Take a look at my screenshots to understand my problem
Custom keyboard can't disable AOSP Keyboard:
SwiftKey can disable AOSP Keyboard:
You can use the following github project to create your own keyboard with the problem https://github.com/alanszlosek/android-keyboard
I already tried to support multiple languages en_US and de_DE, but without success
Which conditions have to be fulfilled so that my APP can be the only selectable on-screen keyboard under Android?
Any suggestions?
