Watch out: the order in which you write the data is important! This method will be passed a Parcel instance which has a number of write methods that you can use to add each field to the parcel. This is done in preparation for transfer. The writeToParcel method is where you add all your class data to the parcel. Public class MainActivity extends AppCompatActivity void onCreate(Bundle savedInstanceState) Let's start by setting up our onCreate method.

Our main Activity will handle the collection of the book details. This is done by reading and writing of objects from Parcels, which can contain flattened data inside message containers. It allows developers to serialize a class so its properties are easily transferred from one activity to another.

In this post I'll show you how Parcelable makes it easy to serialize classes for sharing between Activities.

An easy way to do this is with Intent.putExtra(), but if you have a lot of structured data to pass, Parcelable may be a better solution. We often need to pass data between Activities of an Android app.
