androidMultiplePermissions.java

private void requestMultiplePermissions() {
    String locationPermission = Manifest.permission.ACCESS_FINE_LOCATION;
    String calendarPermission = Manifest.permission.WRITE_CALENDAR;
    int hasLocPermission = checkSelfPermission(locationPermission);
    int hasCalPermission = checkSelfPermission(calendarPermission);
    List<String> permissions = new ArrayList<String>();
    if (hasLocPermission != PackageManager.PERMISSION_GRANTED) {
        permissions.add(locationPermission);
    }
    if (hasCalPermission != PackageManager.PERMISSION_GRANTED) {
        permissions.add(calendarPermission);
    }
    if (!permissions.isEmpty()) {
        String[] params = permissions.toArray(new String[permissions.size()]);
        requestPermissions(params, REQUEST_PERMISSIONS);
    } else {
        // We already have permission, so handle as normal
    }
}

1. in this case, do I need to override onRequestPermissionsResult() ??
   and what will I check there? (all the permissions requested)?
2. I try it(the code above) I just get one dialogue, thus one request!! when allow I wait for another and not get it..
