I’m dealing with the multiple screen support issue of android applications. To support different screen size, I followed the second answer in this thread, which is creating those folders in the file system.

However I didn’t create these folders through eclipse and actually I don’t know whether we can do that. I created them directly in file system. And then, I renamed xml files and add one new xml file in the original layout folder. Next I copied the xml files in the original layout folder to each of the new directories. Question is: Is it right steps to create different screen size layouts?

After this, I go to activities (the .java files) to change the layout names, since I renamed the xml files. However I cannot find the renamed files but the original ones. So I followed this thread since I also get the same problem. After doing project->clean, I have error symbol (the red cross) on each of my activities, and turned out in the imports, import com.mylocalname.R; cannot be resolved since R.java is not generated. I didn’t import android.R.

According to what I found, R.java is not generated maybe because xml file has some errors. However I cannot see any red cross on those files. So how to fix this problem?

So the project is in a mess now. Does anyone have an idea on how to solve the problem? Thanks a lot in advance.

EDIT:

I’m using android platform 4.1 and API level 16.

The xml files’ graphical layouts in the layout folder (not in the layout-X or layout-X-X folders):

    Did you check the problems view in Eclipse? If one or more XML files have an error in them, it should definitely be on that list.

    As far as I can remember XML files will not have a red cross on them like Java files – I can’t confirm that right now though. But when you open up the file the error should be displayed in the graphical view and in source view as well (red x next to line with error).
