I have developed a custom keyboard (IME) for Android that I’m able to install and it works just fine on the device.

The next thing that I want to achieve is to make this keyboard as the default keyboard on a custom AOSP that I’m building.

I’m having trouble finding which changes I need to do in AOSP to change the default keyboard.

Would appreciate any help.

My last resort would be to replace the source code of the packages/inputmethods/LatinIME and build it with the system.
