Default [Q] Combine 2 android projects

Hello xda-developers,

I Have a question: I have made 2 different projects to try some stuff out and to learn about programming in Java for android. But I want now to make those 2 projects 1.

I have made a music application and a sliding menu and now i want to implement the sliding menu in the music player application. I have an idea about how to do it, but to make sure i don't mess things up, I just want your help. So i have a bit of an idea about where i should place all the files. But what should i do with the MainActivity.xml? Better said, how could i combine those mainactivity files?

In a nuttshell i want to combine 2 android projects.

Oh, About the other files that aren't the MainActivity.xml, should i put them in the folder where they are in now? for example the files that are in the res folder (Sliding Menu) can i put those files also in the res but then in the (Music App)

I hope you understand it xD,

Thanks anyway for your help
