I guess this could be a common problem for new android developer like myself so I thought to ask it even so it is not a big deal. I would like to have both the current published stable version of an app and the under development version on my device. Yet when I want to install both I get

Re-installation failed due to different application signatures.
You must perform a full uninstall of the application.

I understand it technically yet I was wondering how I could have an easy way around this so I can have both application on my phone. I could change the package name for the time being but I hope there is an even more straight forward way to get it done.

Thanks

UPDATE

Solution as given by "Marc Bernstein" in the following post - thx Algo for posting the link to it

Just change package name of your published and development version Application. Changing Package name is really very simple and easy, follow that post

The "published" version should be signed using a release keystore.

The "development" version should be signed using a debug keystore.

At installation time, Android will complain that the two applications (having the same package name) have different signatures, and won't install the latest one (Re-installation failed due to different application signatures.).

To fix this (normal) behavior, change the package name of your application while developing it (ex: com.example.myapp-dev).
