This project is in it's early stages, and hopes to generate some interest from other developers who might take it further.
I am aiming to make a boilerplate software keyboard for Android devices which uses a web-view to allow the main interactive area to be written in javascript and HTML. This should allow front-end developers the chance to create interesting alternative interfaces for android keyboards without learning a lot of Java and Android development.
I plan to add more hooks to the native interface to be accessed via javascript function calls.
If you have android-sdk-9 installed, you should be able to build this using ant build from within the project's SoftKeyboard directory (at least it works for me with my setup). Other building instructions welcome, please let me know how to do it using Eclipse for example...
Once built, install the bin/SoftKeyboard-debug.apk file to your android device or emulator.
