title: apktool build apk fails
body: <p>I am experiencing very annoying problems with the application apktool problem.
  I do not understand what i am doing wrong, or what the problem is.
  I tried this on debian , and on linux mint. I used different versions of apktool, </p>
  
  <p>resulting in the same error:</p>
  
  <pre><code>I: Checking whether sources has changed...
  I: Checking whether resources has changed...
  I: Building resources...

  <p>It seems it can not use aapt , but i read about apktool.
  And it seems that aapt is build inside apktool , why is it not working ? </p>
