Mirah Android app generator. Also see https://github.com/mirah/pindah
This project (tentatively called Mirahndroid) generates an Android app that's ready for you to write in Mirah.
Before you use it, you'll need to install all of the things that you'd need to compile an Android app--the JDK and the Android SDK. Obviously, you'll need mirah as well, and mirahc will have to be in your path.
Create an app using mirahndroid create
(use mirahndroid help create
to see the params).
You can compile your app by running ant debug
in the root of your app.
Install it by running adb install -r bin/YourAppName-debug.apk
