Android versions

Year by year, Android has increased its maturity level with each new version. Every version introduced new set of features from the user interface to customizations to flexibility to security. In terms of names, these versions are based on names of candy, chocolates, and other sweet stuff, such as Kitkat, Lollipop, and Marshmallow, but that's what makes Android a little more understandable to consumers and developers as well.

The following table highlights the main features of the different Android versions with their API levels as well:

The table only shows the changes made by Android operating system's developer, Google Inc. But due to Android's open source nature, other mobile manufacturing companies have also changed and introduced new features and modifications into Android. For example, Samsung has made a custom touch interface called TouchWiz, and HTC has made a custom user interface called HTC Sense. Similarly, Sony has introduced a custom user interface called TimeScape.
