How must I go about coding to get an app to query the state of a device, through internet protocol to see if its on or off.
public void port0156 (View view) {
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://192.168.2.66/index.html?o0=1");
}

You can register a broadcastreceiver to monitor connectivity changes.
In manifest :
<receiver android:name="com.yourpackage.NetworkChangeReciever" >
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
</receiver>
the class in com.yourpackage :
public class NetworkChangeReciever extends BroadcastReceiver {
private final static String TAG = "NetworkChangeReciever";
public interface NetworkChangeRecieverListener {
public void OnNetworkChangeReciever(boolean wifiConnected);
}
@Override
public void onReceive(final Context context, final Intent intent) {
final ConnectivityManager connMgr = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
final android.net.NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
final android.net.NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (wifi.isAvailable()) || mobile.isAvailable()) {
Log.d(TAG, "Network Available.");
}
else {
Log.d(TAG, "Network Unavailable");
}
}
}

You can see if the app is online (or reachable) by seeing if it returns a ping you can easily do this by using OS and parsing the output.
