How to add Project to use everywhere without changing anything in another project

Question

I really apologize, if this question has been answered earlier, I haven't found any appropriate answer so I am asking this one.

I have developed an android application. Now I want to develop same application with different splash screen and logo. So I want to use my earlier project for development so that if some changes happen in logic I can track them easily.

What i am trying to do is that add this project and use the project as library every where.

(Project 1 -> Parent project which I want to use as library)

(Project 2 -> Child project where I want to use the parent project) I went to Project 2 (where I want to add/use parent project as library)
project properties -> Java Build Path -> Project -> Add then added the Project1 (parent project)

Now in MainActivity of the Project2 (child project) where I am using the Project1

MainActivity:

package child.project.appStar;
 public class MainActivity extends parent.project.appStar.MainActivity {

 }

Now is there anything else that I need to add or can I simply run this project in my devices?

Any kind of help would be really appreciated.

Answer 1

You can make the main project as library project. IF you using eclipse open the main project project.properties file and add this :

 android.library=true
 manifestmerger.enabled=true

And don't add any main/launcher intent in any activity of manifest.xml file.

Child/Sub project add these lines on the project.properties file. "../MainProject" is the path of ur main project and "MainProject" is the project name. {make sure these are correct.}

 android.library.reference.1=../MainProject
 manifestmerger.enabled=true
 android.library=false

Then at sub project you just need to import the main project files .. and u can access them.

 import com.MainProject.myActivity;

 public class MainActivity extends myActivity{ }
