Mobile applications do not live alone in the device and user context, and this is true for every level of applications, from simpler single-purpose applications to more complex ones. An application may need to access hardware features such as Bluetooth, the camera, import a contact to let the user interact with friends, or share content to other apps and users. So, a developer needs to make the application aware of the user and the device.
In this chapter, you will learn how to integrate an app to the user context, such as displaying and launching a URL, managing platform permissions, launching a phone's camera, and importing a contact.
The following topics will be covered in this chapter:
- Launching a URL from the app
- Managing app permissions
- Importing a contact from a phone
- Integrating the phone's camera
