Android - Multiple .apk file from single code base

Question

I had developed 3 applications in android where the major functionalities are the same but the UI looks different. Images and the background color of the screens are different.

NOw, i want to create a single code base from which i can generate multiple .apk files for the 3 apps.

I tried creating 3 different packages for src folder for the 3 apps. But i dont know how to set the res folder for these apps.

Need pointers on creating a single code base from which we can generate multiple .apk files which includes only the respective src and res folders.

Answer 1

• Use an Android Library Project that contains all your common code.
• Create separate Android projects that reference the Library Project (you will need to copy your Manifest into each of these and make sure all components are declared with their full Java package name).
• Put any resources specific to each app (drawables, colors etc) into the individual project resource folders and they will override similarly named resources in the library project at build time.

Answer 2

i think the best option is to use ant, you'll need to add an ant target for each build and change the resource folder. if you use the generated build.xml, the res folder is defined like this <property name="resource.absolute.dir" location="res" /> so you'll want to override that
