copied!<p><strong>UPDATE:</strong> updated the codes to avoid <code>NetworkOnMainThreadException</code></p> <p>I'm currently using the following method to determine whether the device can access the internet or not:</p> <pre><code>public class NetworkConnectivityHelper { public void isDeviceConnectedToInternet(final Activity activity, final ResultCallback callback){ new Thread(new Runnable() { @Override public void run() { boolean isDeviceConnectedToInternet = false; NetworkInfo activeNetworkInfo = ((ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo(); if(activeNetworkInfo != null && activeNetworkInfo.isConnected()){ try { InetAddress.getByName("google.com").isReachable(2); isDeviceConnectedToInternet = true; } catch (UnknownHostException e){ isDeviceConnectedToInternet = false; } catch (IOException e){ isDeviceConnectedToInternet = false; } } final boolean result = isDeviceConnectedToInternet; activity.runOnUiThread(new Runnable() { @Override public void run() { callback.done(result); } }); } }).start(); } public static abstract class ResultCallback{ public abstract void done(boolean connected); } } </code></pre> <p>call this by:</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); .... //Populate NetworkConnectivityHelper networkConnectivityHelper = new NetworkConnectivityHelper(); networkConnectivityHelper.isDeviceConnectedToInternet(activity, new NetworkConnectivityHelper.ResultCallback() { @Override public void done(boolean connected) { if (connected) { //Yey, the device is connected. //Now, do some work }else{ //The device is disconnected } } }); .... } </code></pre> <p>hope this helps!</p>
