Updating an existing build on Android device

Questions & Answers
1

If I want to make an update to my application whilst testing my build on an android device, do I have to uninstall the app from my device and re-install the new APK every time?

Or is there a way of getting it to update the installation on my device without doing a clean install each time?

Many thanks!

If it has the same Key it should not require uninstallation of the old apk. Of course it goes without saying that installation of the new apk is required.

There are situations in which Android will inform you of the old install and prompt to remove it for you.
