I just wanna ask if what is the simplest way to integrate two or more project.
For example I've done calculator android app and paint android app, now I want to create new project which is the allInOneApp . In the main activity of allInOneApp is a list of buttons. button for calculator, button for paint etc.
My idea for this is to copy paste all the classes and xml etc of the projects to allInOneApp and when I click the specific button it will intent to one of the projects. Is there any other way except copy paste.
