  <p>I can't create a new android project, neither in windows or Ubuntu! I have 2.3.3 and 2.2 and 4.0 versions of android sdk and I want to create a new project using 2.3.3 version. But after creating the project it says <strong>R cannot be resolved to a variable</strong>.</p>
  
  <p>I have read all the questions related to this topic and I have done all the suggested solutions but none of them worked for me. (Clean Project , check Android version in Build path menu, checking xml files, lower case xml file names and etc)</p>
  
  <p>Since I'm using a blank project, it's not because of some incorrect xml files or some errors in java codes.(for god sakes its a blank project!! how could it be broken?)</p>
  
  <p>I don't know what to do. any suggestions would be appreciated. </p>
