R.java is automatically generated jave file.
- This was due to some problem in the XML layout file that prevented the application from being built, so make a sure any error on xml file in your project and correct that.
- Use the Ctrl + Shift + O command(window) 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, which is more helpful.
- Sometimes, you may through: Go to Project > Properties > Java Build Path > tab [Order and Export] > Tick Android Version , Check this. and Run the Current Project. Like this
- Sometimes, you may have a images naming conventions (may contain only [a-z0-9_.]), the R.java class might not generate, that is in res/drawble folder, please check this and correct in appropriate format.
- Another, important but not many developer watch this, sometimes, this error occurs, when you missing this import. import android.R; or may be this accorading to your project name like this- > import com.example.appname.R;.
- And, Finally last but not the list, after all tips not working please dont forget do this:
Close all files, clean project, restart Eclipse.
