Currently I am using Eclipse IDE with ADT plugin for my Android application development, but when I change the same source code to another machine with same IDE and ADT Plugin, the generated APK cannot be installed as upgrade, android show a error message (I don't remember the error message)
Since that error, I use the original IDE to compile an APK and finally upgrade on the installed devices.
What I need to add/change in other machines to avoid install errors?
Thank you.
