Question

I am developing an android app in which I have included a library project, I am able to use the resources of library project (ie layouts, styles etc) inside my main project. But I want to use the resources of my main project inside my library project. Is there any way to do that? I am stuck at this problem for quite a time.

You can create dummy resources inside your library project, and anything with the same name in the main project will override it.

Example:

LibProject/res/values/strings.xml:

<string name="greeting">Hello from Library Project</string>

MainProject/res/values/strings.xml:

<string name="greeting">Hello from App Project</string>

Then, wherever you use R.string.greeting, even in your library project, the value from the main project will be used.

From the docs:

The application itself has highest priority and its resources are
always used in preference to identical resource IDs defined in
libraries.
