title: How to rezip an APK file?
body: <p>I have 2 APK files, both just different versions of the same project. I need to replace some pictures and layout xml pages in the RES folder of one of them using the files from the other.</p>
  
  <p>While I can unzip both of them no problem in Windows 7, my Android phone doesn't finish the installation of the new APK if even one file was replaced. If I unpack and rezip the APK file without any changes, it installs correctly. I use WinRar to zip the files into a ZIP file, then renamed it APK.</p>
  
  <p>What am I missing here?</p>
