Answer 1

write this code in your create method

if (internetConnection.hasConnection(BankAccount.this))
{
   // call your methods
}

else
{
    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
    alertDialogBuilder
            .setMessage("No internet connection on your device. Would you like to enable it?")
            .setTitle("No Internet Connection")
            .setCancelable(false)
            .setPositiveButton(" Enable Internet ",
                    new DialogInterface.OnClickListener()
                    {

                        public void onClick(DialogInterface dialog, int id)
                        {
                            Intent dialogIntent = new Intent(android.provider.Settings.ACTION_SETTINGS);
                            dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            context.startActivity(dialogIntent);
                        }
                    });

    alertDialogBuilder.setNegativeButton(" Cancel ", new DialogInterface.OnClickListener()
    {
        public void onClick(DialogInterface dialog, int id)
        {
            dialog.cancel();
        }
    });

    AlertDialog alert = alertDialogBuilder.create();
    alert.show();
}
