Difference between debug and release apks
<p>I am new to android as well as android studio.
From my experience in visual studio, when we test the .exe in another machine we copy the release folder and .exe.</p>

<p>But in android studio I am seeing my colleagues test the debug apk by copying and deploying in other systems using USB drive. seems working also.
May I know what is the consequence of deploying that version? Is the release version relevant only for a play store purpose?</p>

<p>What is the technical difference/consequence other than that debug version contains debug information which may makes it slow or bulky?</p>
