Answer 1

You can use the following method:

 ConnectivityManager conectivtyManager = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE); if (conectivtyManager.getActiveNetworkInfo() != null && conectivtyManager.getActiveNetworkInfo().isAvailable() && conectivtyManager.getActiveNetworkInfo().isConnected()) { isConnected = true; } else { isConnected= false; } 

Hope this helps!

For wifi:

 ConnectivityManager mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = mgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI); connected = networkInfo != null && networkInfo.isConnected(); 

For mobile devices:

 ConnectivityManager mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = mgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); connected = networkInfo != null && networkInfo.isConnected();
