SDK represents Software Development Kit, which, however it might invoke pictures of an attaché loaded with spy apparatuses, is only an extravagant name for a bunch of pre-bundled code.

Suppose you need to incorporate an online media stage like Facebook with your app. You would download a code library from Facebook and afterward let Gradle know that you’re utilizing it so when your application incorporates, your code remains efficient.
