65This sample demonstrates how to connect to the network and fetch raw HTML using
66[`HttpsURLConnection`][4]. Since API 11, it is required by default that all network
67operations run on a background thread in order to avoid hanging on the UI thread. Only
68when the network response is ready should the work return to the main thread to update
69the UI. An [`AsyncTask`][3] is a viable background task manager that is used to perform
70the network operation and return to the UI thread upon completion.
71
72The sample also utilizes the [`ConnectivityManager`][1] to determine if you have
73a network connection, and if so, what type of connection it is.
74
75Using an [`AsyncTaskLoader`][6] or an [`IntentService`][5] are two common alternatives
76for managing longer running background work.
