title: Recover the R.java file
body: <p>While compiling my project, I lost my R.java file.</p>
  
  <p>I recreated the new project and replaced all my .xml files, .java files, and all my images in the project, but in that project I also lost my R.java file.</p>
  
  <p>What should do to solve this problem? Can I recreate my R.java file for the project?</p>
