How to merge source code from 2 project Android

Question

Very sorry if my questions are stupid. After searching, I get the source code of 2 open source projects. Somewhat difficult to describe, but it is an assistant app instead of google assistant. A project is similar to the framework for the assistant, and the other project that receives information from the assistant to search. I want to put two projects into one and export a single apk. It's hard to get started, so please help me.

You can import your old project in the new as a module. See the following instructions.

1. Find your old project folder by right-clicking on the project name in the "Package Explorer" -> Properties -> "Location".
2. Open your new project, go to File -> New -> Import Module, browse "Location" path and choose your project.
3. Go to Project structure -> Dependencies tab and then add that module as a dependency.
