Important Library for Android

Using Parceler

Although creating Android Parcelables is usually at least 10x faster than using Serializable, creating Parcelable objects requires creating a lot of boilerplate code in defining exactly the stream of data that should be serialized and deserialized as documented in this section.

Reducing View Boilerplate with Butterknife

Butterknife is a popular View "injection" library for Android. This means that the library writes common boilerplate view code for you based on annotations to save you time and significantly reduce the lines of boilerplate code written.
