Reverse engineer the app (because original developer became unreachable).

Reverse engineer the iRT GTasks Outliner app (because original developer became unreachable). [login to view URL] I tried to reach the developer in e-mail & Google+, but got no response. I also offered payment to implement new features, but I did no receive answer. I'm afraid, something happened with the developer, so the app will not be developed anymore. The only solution to have new features implemented into the app to ask another developer to reverse engineer the code and implement new features. Milestone 1 ($15): - Reverse engineer the app (because original developer became unreachable). Make the reverse engineered source code available to a non-public GIT repo for me. I should be able to clone it for myself. - The code should successfully build in Android Studio (under Windows 7). The work is considered to be done if: - I get all the changes into a non-public GIT repo, so I can clone it to my computer. - I should be able to download from the repo the compiled, signed apk file.
