Displaying a Chooser

For users to select the app they want to use for sharing, you need to create or launch a chooser control that Android displays in the user interface. Here’s how.

1. Create a new class named Share in the com.androiddevbook.onyourbike.chapter8.helpers package. Create a static string named CLASS_NAME to store the class’s name, and create a constructor in the usual way. Create a property of type Activity, and set this from the activity parameter passed into the constructor (see Listing 8.28).
