Xamarin.Android - WeatherREST
This sample app accompanies Call a REST Web Service. You can use this sample to learn how to call a RESTful service via HTTP and handle/parse the JSON results asynchronously.
This example app sends latitude and longitude information in an HTTP request (to Geonames.org) and gets back weather information for that longitude and latitude. The user keys in the global latitude and longitude parameters and then presses Get Weather. When the HTTP response is received, the app parses the results and displays a subset of the weather information in textbox fields in the lower half of the display:
This example uses System.Json to parse the results of the HTTP
request. The HTTP request, response, parsing, and display are handled
asynchronously via async/await.
Note that this sample uses a geonames.org demo account, which supports a limited number of accesses. If the display is not reporting weather information, check your IDE output window to view the HTTP response and see if it contains a "daily limit has been exceeded" message.
You will need an Android device or emulator with a large screen (such as a Nexus 5 or an AVD with the WXGA720 skin) to view the results.
