Which Android opensource project to create for a resume?

Question

Android

It is now considered good practice to have a github repository with a couple of open projects in your resume, by which you can determine the quality of the code of a particular developer. Faced with this point when editing my resume, I could not think of something to release on github, something to show the skill and present something useful.
Of course, you can write something banal with a lot of functions from the API, but completely useless, you don’t want to do that.
Actually, the question is, what can be presented in your open source github, so that it really looks like a useful open source project that will be of interest not only to me?

Answer 1

Library. Any. In android, there are a lot of places that can be made more convenient. Moreover, this is a good option to improve the processing of annotations and generalizations.
