title: appcompat_v7 error when new android application created
body: <p>1) So far whenever I create android project, I get a java main class which extends activity, and an XML file... that's it, but now after recently upgrading my android eclipse, whenever I create a project the main java file extends action bar activity instead of just activity and a fragment class is also created with the XML file, and on top of all this a new folder appcompat_v7 gets created automatically with red cross as an indication of error over it, I am new to android development and all this stuff stopping me from continue, as I do not know why all this is happening and how can I tackle this problem. </p>
  
  <p>2) When a project is created i get this error message in my console:</p>
  
  <p>[appcompat_v7] WARNING: unable to write jarlist cache file C:\Users...\workspace\appcompat_v7\bin\jarlist.cache</p>
  
  <p>Any suggestions on how solve such problems and what is wrong with my android eclipse highly appreciated</p>
