title: Android filesDir shown as read only
body: <p>While trying to write a simple file to the applications file directory with <code>phonegap-1.0.0</code> I get an error with code 5 - <code>NO_MODIFICATION_ALLOWED_ERR</code>. The method where I get the directory is like this:</p>
  
  <pre><code>function gotFS(fileSystem) {
          fileSystem.root.getFile('file:///data/data/package.name/files/ff.txt', null, gotFileEntry, fail);
      }
  </code></pre>
  
  <p>As far as I know, the files directory should be writable by the application, and writing to it with a <code>BufferedWriter</code> was successfull. I tried only leaving file name, without file:/// and data/data/package.name/. I tried many different versions of Phonegap and many methods only to read/write a file and seems like nothing works. Any hint would be appreciated.</p>
