• 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.
• R is a generated class. If you are using the Android Development Tools (ADT) it is generated whenever the project is built. You may have 'Build Automatically' turned off. Turn it on and build your project.
• Mistakes in your xml views could cause the R.java not to be generated. Go through your view files and make sure all the xml is right!
• Remove, if any import android.R;
