AsyncTask is used to perform the fetch on a background thread. 7*d353a188SXin Li 8*d353a188SXin LiIntroduction 9*d353a188SXin Li------------ 10*d353a188SXin Li 11*d353a188SXin LiThis sample demonstrates how to connect to the network and fetch raw HTML using 12*d353a188SXin Li[`HttpsURLConnection`][4]. Since API 11, it is required by default that all network 13*d353a188SXin Lioperations run on a background thread in order to avoid hanging on the UI thread. Only 14*d353a188SXin Liwhen the network response is ready should the work return to the main thread to update 15*d353a188SXin Lithe UI. An [`AsyncTask`][3] is a viable background task manager that is used to perform 16*d353a188SXin Lithe network operation and return to the UI thread upon completion. 17*d353a188SXin Li 18*d353a188SXin LiThe sample also utilizes the [`ConnectivityManager`][1] to determine if you have 19*d353a188SXin Lia network connection, and if so, what type of connection it is. 20*d353a188SXin Li 21*d353a188SXin LiUsing an [`AsyncTaskLoader`][6] or an [`IntentService`][5] are two common alternatives 22*d353a188SXin Lifor managing longer running background work. 23*d353a188SXin Li 24*d353a188SXin Li[1]: https://developer.android.com/reference/android/net/ConnectivityManager.html 25*d353a188SXin Li[2]: https://developer.android.com/reference/android/net/NetworkInfo.html 26*d353a188SXin Li[3]: https://developer.android.com/reference/android/os/AsyncTask.html 27*d353a188SXin Li[4]: https://developer.android.com/reference/javax/net/ssl/HttpsURLConnection.html 28*d353a188SXin Li[5]: https://developer.android.com/reference/android/app/IntentService.html 29*d353a188SXin Li[6]: https://developer.android.com/reference/android/content/AsyncTaskLoader.html 30*d353a188SXin Li 31*d353a188SXin LiPre-requisites 32*d353a188SXin Li-------------- 33*d353a188SXin Li 34*d353a188SXin Li- Android SDK 27 35*d353a188SXin Li- Android Build Tools v27.0.2 36*d353a188SXin Li- Android Support Repository 37*d353a188SXin Li 38*d353a188SXin LiScreenshots 39*d353a188SXin Li------------- 40*d353a188SXin Li 41*d353a188SXin Li<img src="screenshots/main.png" height="400" alt="Screenshot"/> 42*d353a188SXin Li 43*d353a188SXin LiGetting Started 44*d353a188SXin Li--------------- 45*d353a188SXin Li 46*d353a188SXin LiThis sample uses the Gradle build system.
