Building # from the Source code
AIDE - free Android application - allows you building (and even developing...) # from its publicly available Source code directly on your Android device. This way you may test not released yet features and learn how AndStatus works.
The whole process is very simple and takes several minutes:
1. Install AIDE to your Android device from https://play.google.com/store/apps/details?id=com.aide.ui
2. Open AIDE, choose option "Code for Experts"
3. Open Files
4. Select "Git..." in the list of "files"
5. Clone # code from this URL: https://github.com/andstatus/andstatus.git
6. Open the cloned project
7. Run it - at this step AndStatus is actually being built and installed on your device.
