Choose Library Dependency, type gson, g-s-o-n…and click the search icon and you'll see…a bunch of libraries displayed.…You're looking for this one, starting…with com.google.code.gson:gson.…And just take whichever version you see here.…It'll always be the most recent version.…Click OK, click OK again and that adds…the dependency to your Gradle build file.…And automatically re syncs the project.…This line of code has been added.…
I'm compiling in the Gson library…and I don't need to go get a JAR file.…
IInstructor David Gassner 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.
