11This sample demonstrates how to connect to the network and fetch raw HTML using
12[`HttpsURLConnection`][4]. Since API 11, it is required by default that all network
13operations run on a background thread in order to avoid hanging on the UI thread. Only
14when the network response is ready should the work return to the main thread to update
15the UI. An [`AsyncTask`][3] is a viable background task manager that is used to perform
16the network operation and return to the UI thread upon completion.
17
18The sample also utilizes the [`ConnectivityManager`][1] to determine if you have
19a network connection, and if so, what type of connection it is.
20
21Using an [`AsyncTaskLoader`][6] or an [`IntentService`][5] are two common alternatives
22for managing longer running background work.
