I created a sticker pack for iMessage users, now I want to create a keyboard extension for android phones which will support all those images so that people who own an android phone can send those same animated png files to their recipients.
This guide can help any developer create the app [url removed, login to view]
The keyboard extension should have all those features
Appropriate layout and features based on keyboard type trait
Autocorrection and suggestion
Automatic period upon double space
Caps lock support
Multistage input for ideographic languages
Ability to switch to the default keyboard.
Also this same keyboard extension should be available for the Iphone users so they can actually use the images outside IMessage.
This guide should be able to help the developer
