In one Fragment, I am using NavController from a context menu, which has a nested menu.

If I try to navigate to one of the nested menu items it gives me the following error:

java.lang.IllegalArgumentException: Destination id == 0 can only be used in conjunction with a valid navOptions.popUpTo

How can I avoid this error and navigate to the nested destinations?

Code for navigation

public boolean onContextItemSelected(MenuItem item) {
    Bundle bundle = new Bundle();
    bundle.putString("FECHA", mDate);
    NavController navController = NavHostFragment.findNavController(this);
    navController.navigate(item.getItemId(),bundle);
    return true;
}

CodePudding user response：

You have to check whether the menuId is 0 or not, this is because your nested menu's root ("Liturgia de las Horas") has no ID and thus it will return 0

public boolean onContextItemSelected(MenuItem item) {
    if (item.getItemId() == 0) {
        return true;
    }
    Bundle bundle = new Bundle();
    bundle.putString("FECHA", mDate);
    NavController navController = NavHostFragment.findNavController(this);
    navController.navigate(item.getItemId(),bundle);
    return true;
}
