How does downloading game updates works?
<p>Let's say I published a game and after some point of time I wanted to release an all new feature for the game. Of course the app must be able recognize and download the update. How does this work specifically with Google Play apps? Does the app download the entire new version of APK from the market and reinstalls itself? I'm using Java for the development, if this info helps. Any tips you can give me about this topic? </p>
