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.
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.
This sample uses the Gradle build system. To build this project, use the "gradlew build" command or use "Import Project" in Android Studio.
