I have created an app with Android Studio that needs a custom keyboard with only a few letters and numbers. I can create alternate keys in the Keyman development IDE but I can't find how to change what is displayed on the virtual keyboard buttons.
Thanks in advance Sam
You'll first need to add the "Touch-Optimised Keyboard" feature in the Details tab in the Keyman Developer IDE.
Once you have added this, the Touch Layout tab will be added which allows you to change the layout for Android (and iOS) devices.
