title: how to set the path to where aapt add command adds the file
body: <p>I'm using aapt tool to remove some files from different folders of my apk. This works fine.</p>
  
  <p>But when I want to add files to the apk, the aapt tool add command doesn't let me specify the path to where I want the file to be added, therefore I can add files only to the root folder of the apk. 
  This is strange because I don't think that developers would never want to add files to a subfolder of the apk (res folder for example). Is this possible with aapt or any other method? Cause removing files from any folder works fine, and adding file works only for the root folder of the apk. Can't use it for any other folder.</p>
  
  <p>Thanks</p>
