This is an example of how to fetch json through an http request asynchronously. I have added my personal project built in Android Studio as well as a folder containing only the raw sources you would need to setup in Eclipse.
=========
Included:
-
android-http-example project (Built using Android Studio)
-
JustTheFiles folder, which contains just the modified files so you can reconstruct this project in Eclipse.
--string.xml goes in your 'res/values' directory of your project --Both MainActivity.java & RetrieveJson.java go in your src --activity_main.xml is a layout, which goes in 'res/layout'
========== Also concerning the AndroidManifest.xml the only important bit you need to see (and use) is the following:
<uses-permission android:name="android.permission.INTERNET"/>
Without this your application WILL crash when it attempts to pull anything.
