Question

I want to add a facebook permission to my users. That is how I do it:

Session.openActiveSession(this, true, new Session.StatusCallback() {
        @Override
         


        

Answer 1

use below code

Session session = getActiveSession();
if(session.isOpened)
{
  List<String> permissions = session.getPermissions();
    if(!permissions.contain("email"))
    {
 Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(MainActivity.this,
                            PERMISSIONS);
                    session.requestNewReadPermissions(newPermissionsRequest);

}
}else
{
Session.openActiveSession(this, true,callback);
}
