Android integrates with a variety of cloud-based and custom web services in a variety of ways, including RESTful services created in PHP or Java, to get, update, and send data over the web. This course shows how you can take advantage of web services, integrations, and libraries to optimize how your app handles network connectivity, errors, data management, and more.
Instructor Dаvid Gаssnеr starts with an overview discussion about available networking strategies, and then dives into how to declare networking permissions, make network requests, handle responses, parse data returned from a web service, and pass user credentials to services that support HTTP basic authentication. He also provides an overview of popular higher-level networking libraries, including OkHttp and Picasso, and offers recommendations for improving performance in network-connected apps. David also covers using static feeds, using dynamic PHP pages hosted on a public server web service, and integrating apps with network data storage.
Topics include:
- Integrating mobile apps
- Communicating with Android
- Preventing app freezes with background threads
- Preparing an app for network communication
- Declaring permissions
- Checking network connectivity
- Retrieving data over the web
- Using traditional APIs
- Using third-party libraries
