1 2 Android NetworkConnect Sample 3 =================================== 4 5 This sample demonstrates how to connect to the network and fetch raw HTML using 6 HttpsURLConnection. AsyncTask is used to perform the fetch on a background thread. 7 8 Introduction 9 ------------ 10 11 This 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 13 operations run on a background thread in order to avoid hanging on the UI thread. Only 14 when the network response is ready should the work return to the main thread to update 15 the UI. An [`AsyncTask`][3] is a viable background task manager that is used to perform 16 the network operation and return to the UI thread upon completion. 17 18 The sample also utilizes the [`ConnectivityManager`][1] to determine if you have 19 a network connection, and if so, what type of connection it is. 20 21 Using an [`AsyncTaskLoader`][6] or an [`IntentService`][5] are two common alternatives 22 for managing longer running background work. 23 24 [1]: https://developer.android.com/reference/android/net/ConnectivityManager.html 25 [2]: https://developer.android.com/reference/android/net/NetworkInfo.html 26 [3]: https://developer.android.com/reference/android/os/AsyncTask.html 27 [4]: https://developer.android.com/reference/javax/net/ssl/HttpsURLConnection.html 28 [5]: https://developer.android.com/reference/android/app/IntentService.html 29 [6]: https://developer.android.com/reference/android/content/AsyncTaskLoader.html 30 31 Pre-requisites 32 -------------- 33 34 - Android SDK 26 35 - Android Build Tools v26.0.1 36 - Android Support Repository 37 38 Screenshots 39 ------------- 40 41 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 42 43 Getting Started 44 --------------- 45 46 This sample uses the Gradle build system.
