title: How to test update of Android application?
body: <p>I need to test application update because it has major changes in database structure</p>
  
  <p>i tried to use adb install -r app.apk, but it says INSTALL_FAILED_UPDATE_INCOMPATIBLE</p>
  
  <p>here everyone says that you need to uninstall app from device, but i need to UPDATE. I think this situation may occur when i trying to update from app from market with release signatures to development apk build from android studio</p>
  
  <p>P.S. sorry for my english if in my post some mistakes, i'm from Russia</p>
