I don't think you should always bump the minSdkVersion to the newest version, because then your app can only be installed on this version and all users with older Android versions cannot use your app, right?

So what you should do is to always bump the compileSdkVersion and probably also the targetSdkVersion.

And when your minSdkVersion is lower than your targetSdkVersion, then you need to carefully handle backward compatibility in your code.
