Missing R.java file even though project cleaned

Question

Every time in code that I have an R, I get an error R cannot be resolved to a variable.

The R.java file appears to be missing.

I have tried cleaning the proj

If you do not see R.java file generation upon creating an Android project, then you probably have missed downloading Android SDK Tools in the Android SDK Manager. In eclipse, go to Window-->select Android SDK Manager Once the Android SDKManager window opens, check the Tools folder and install. Once the installation is completed, restart the eclipse IDE. Build your project and you can see the R.java file generated under the gen folder of your Android project.
