title: Edit '/res/drawable' from '.apk'
body: <p>I have an <code>.apk</code> application which has horrible graphics, so I've uncompressed it and I've edited most of the textures.</p>
  
  <p>But, when I try to compress it again and install it, Android says "Application couldn't be installed" (not literally). If I don't make changes in the textures the application gets installed, after uncompressing it too.</p>
  
  <p>Is there a way to modify files from an .apk? The app isn't mine and I obviusly haven't changed the names of the files. The new textures have a different resolution, may this be the problem?</p>
  
  <p>Thanks in advance.</p>
