Firebase Orderbychild And Equalto() Queries Don't Work

I'm developing an Android app with the following Firebase database table: 'posts': { 'id_1': { 'author': 'google:111527135678918251124', 'color': -2960686, 'creationTime': 14

Solution 1:

About the ordering, I think the problem is that I'm retrieving data as a HashMap which is itself unordered.

As suggested in the comments the second case needs .equalTo(1) instead of .equalTo("type",1) because it's preceded by the .orderBy() method.
