Android NetworkConnect Sample

This sample demonstrates how to connect to the network and fetch raw HTML using HttpsURLConnection. AsyncTask is used to perform the fetch on a background thread.

Introduction

This sample demonstrates how to connect to the network and fetch raw HTML using HttpsURLConnection. Since API 11, it is required by default that all network operations run on a background thread in order to avoid hanging on the UI thread. Only when the network response is ready should the work return to the main thread to update the UI. An AsyncTask is a viable background task manager that is used to perform the network operation and return to the UI thread upon completion.

The sample also utilizes the ConnectivityManager to determine if you have a network connection, and if so, what type of connection it is.

Using an AsyncTaskLoader or an IntentService are two common alternatives for managing longer running background work.

Pre-requisites

  • Android SDK 27
  • Android Build Tools v27.0.2
