found the solution quite easily
Intent shortcutIntent = new Intent(context.getApplicationContext(),MainActivity.class);
shortcutIntent.putExtra("stop", stopName);
shortcutIntent.setAction(Intent.ACTION_MAIN);
Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, stopName);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
Intent.ShortcutIconResource.fromContext(context.getApplicationContext(), R.drawable.ic_launcher));
addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
context.getApplicationContext().sendBroadcast(addIntent);
get the extra "stop" on ActivityMain.java ...
Intent i = getIntent();
String stop = i.getStringExtra("stop");
