Problem with R.java class
Since a few videos ago, i started to get errors on any method related with R.java class. After tracking down this problem, I found this note in the Android documentation:
Note: Eclipse sometimes likes to add an "import android.R" statement at the top of your files that use resources, especially when you ask Eclipse to sort or otherwise manage imports. This will cause your make to break. Look out for these erroneous import statements and delete them.
While going through the Android sample tutorials, I would often use the Ctrl + Shift + O command to "Organize Imports" and generate any missing import statements. Sometimes this would generate the incorrect import statement which would hide the R.java class that is automatically generated when you build.
Please include this note in yours videos, because beginners like me get confused. Thanks

Try checking your layout and other xml files to make sure they are lower caps and following proper naming conventions

Make sure that you do not have any imports of R.java.class in all your files, and after do a clean in eclipse. Project(top navigation) -> Clean -> Select your project.
