[android-developers] Re: Can a core class access resources at the app layer?
Thanks, Dianne. I tested your suggestion with two apps, where one app gets resources from another app, and it worked. Doing it at the framework layer is more difficult, but it may be more of a build problem. I made a change to frameworks/base/core/java/android/widget/ AbsListView.java did a mmm frameworks/base, and then make snod. I don't *think* I saw my change reflected, but maybe you could tell me if make snod should work, or if i need to do a full make. But as another approach, I also wanted to ask this: In the file list_selector_background.xml located at frameworks/base/core/res/res/ drawable/, can I change the line: item android:state_focused=true android:drawable=@drawable/list_selector_background_focus / to something that points to my resource, such as: item android:state_focused=true android:drawable=@drawable/ com.mycompany.myapp.my_list_selector_background_focus / Is there a way to do this? thanks for your help.

Hi, let's move this discussion to android-porting, this is well outside the scope of programming with the SDK. (But no, you can't do that.)

Whoops I thought this was android-platform, my bad. Anyway, yes I will move it to android-porting.
