    <p>I want to listen for when the GoogleTV device is disconnected and then display a pop up warning.</p> <p>I thought I had achieved this by the below code, but then discovered that I am only warned about the disconnection when the device's ethernet cable is disconnected: i.e. LAN. I am not alerted when the router's input ethernet cable is disconnected: i.e. WAN.</p> <p>I have discovered that when disconnecting the LAN cable, the GTV device will lose its IP address, but when disconnecting the WAN cable, the GTV device WILL still have an IP address - that is why it I am not alerted that the app lost a connection.</p> <p>So how do I check when a GoogleTV device is no longer connected to a WAN? What do I need to add to the below code to do that?</p> <pre><code>startListeningToNetwork(); private void startListeningToNetwork() { if(_networkStateReceiver == null){ //Listen for when the network changes. If app loses internet before webView has loaded, then display error message. _networkStateReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if(!isConnected()){ showNetworkErrorDialog(); } else { closeNetworkError(); } } }; IntentFilter networkFilter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION); getActivity().registerReceiver(_networkStateReceiver, networkFilter); } } private boolean isConnected() { ConnectivityManager cm = (ConnectivityManager) getActivity().getSystemService(Context.CONNECTIVITY_SERVICE); Toast.makeText(getActivity(), "isConnected? " + (cm.getActiveNetworkInfo() != null &amp;&amp; cm.getActiveNetworkInfo().isConnected()) , Toast.LENGTH_SHORT).show(); return (cm.getActiveNetworkInfo() != null &amp;&amp; cm.getActiveNetworkInfo().isConnected()); } </code></pre>

    1. CO`return InetAddress.getByName("google.com").isReachable(10*1000);` :)

    2. COisReachable() is fine if I want to know if there is an internet connection right NOW. But I also want to be alerted when the internet is lost or is re-obtained. That is why I use the registerReceiver() method mentioned above. With the isReachable() method, I guess I could make a timer to constantly ping "google.com", but that seems like it would NOT be a best practice.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
