In this blog, I would like to share my experience of working with Android legacy code which work well for me so far. First of all, when I get into an Android project which contains legacy code . I will ask about the current situation of the application: Current features Current know issues Current patterns are being used in the projects Current overall structures Current way of working of the team Current parts in which contain legacy code Current UI tests Current Unit tests Then I spent some times to get familiar with the current features by getting a phone and try out the current features and the known issues and take notes of those things. In my experience, the applications can be complicated that even the ones who develop it don't know all the features and known issues of it. Therefore, taking note and comparing with the transferred knowledge is a good way to start understanding the application. Now, hopefully, I have a good idea of what I am dealing with. Then
Chasing simplicity.
