Android R.java keep not updating

Question

I'm a new learner in android programming. I have reading book about android programming and currently practicing. I have one little problem but it's annoying.

My R.java file does not updating with any change I made. Like when I drag an image, or create XML file. The R.java does not updating. I have search about the problem and found a solution to clean the project and then make changes to manifest.xml to force generated of R.java file. When I doing that the R.java update with any change I made previously. But when I made new changes the R.java does not update again. Must I do that clean and force generated R.java file every time I want to run my project?or is there is some way to fix it?

The Build Automatically is checked by the way.

Answer 1

If you run a clean on the project, R.java should be updated or regenerated. If it doesn't, there probably is some issue in the res/ folder.
