Keeping both release and beta versions of app on my phone
<p>I recently uploaded my apk to the Playstore for my beta testers and I would like to keep this app on my phone.</p>

<p>But if I build it from android studio for further tests, it says :</p>

<blockquote>
  <p>Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]</p>
</blockquote>

<p>I think it's all about one being in debug mode and other in release mode.</p>

<p>I thought of changing applicationId with a flavour on debug, but I didn't found how to properly do it, and it prevent me for using content providers.</p>

<p>Is there a better way to do this ?</p>
