A few questions : What implications does upgrading an app have on stored data i.e. Preferences and database? Does the system perform a clean install of the new version(i.e. remove the older version and then install the new) or something else? What if the user wants to retain the stored data- say values in the shared preference or a sqlite database? How can I emulate this app-update-install scenario? If I have a version 'x' installed on my emualator and I do a adb install of version 'x+1' I am getting INSTALL_FAILED_ALREADY_EXIST error. Should I try hosting the new apk on a Web server, will the Package Manager take this as an update?
