I've been working on an overhaul of the Android app, and it's finally in a state where people can start using it! Right now it's read only, but replying to comments and posting new threads will be completed this week. You can download the APK here:
To install it on your phone or tablet, copy it over to the SD card and use the File Explorer to install it.
For the CSE MGoBloggers out there, you can track progress of the app at https://github.com/SeanPONeil/MGoBlog . The dev branch is where all the fun stuff is happening.
