title: Don't need R, but getting R cannot be resolved to variable error
body: <p>I'm making my first app within eclipse, and I've been watching a YouTube playlist to help along the way (Link below). 
  Currently I'm working on building buttons and linking pages to each other. The problem I'm running into is an <code>R</code> cannot be resolved to a variable error, for any code like the following.</p>
  
  <pre><code>Atlantic = (Button) findViewById(R.id.Atlantic);
  </code></pre>
  
  <p>or</p>
  
  <pre><code>setContentView(R.layout.mainactivity);
  </code></pre>
  
  <p>The quick fix wants to import <code>android.R</code>. When you do this, the ID kicks off this error "ID" cannot be resolved or is not a field.
  The odd thing is, sometimes I can just remove import <code>android.R</code> and it will work. However, it tends to come back after adding a picture or something to another screen (that has nothing to do with any Java code (yet) or any ID (yet))</p>
  
  <p>BTW, I don't know if this helps. for the ID I use the <code>"@+id/bla"</code> trick.</p>
