Android Developer Interview Question:

Tell us how do you supply construction arguments into a Fragment?

Submitted by: Muhammad

Construction arguments for a Fragment are passed via Bundle using the Fragment#setArgument(Bundle) method. The passed-in Bundle can then be retrieved through the Fragment#getArguments() method in the appropriate Fragment lifecycle method.

It is a common mistake to pass in data through a custom constructor. Non-default constructors on a Fragment are not advisable because the Fragment may be destroyed and recreated due to a configuration change (e.g. orientation change). Using #setArguments()/getArguments() ensures that when the Fragment needs to be recreated, the Bundle will be appropriately serialized/deserialized so that construction data is restored.
