How to Query nested object in Firebase Android

I am using Firebase in android.

I am having trouble in querying the below json.

I am having is an array of objects. A single object is posted below:

{
      "currency" : "₹",
      "groups" : {
        "-L9Q5d3T_XBBQGJygGqJ" : {
          "group_id" : "-L9Q5d3T_XBBQGJygGqJ",
          "group_name" : "Group 1"
        }
      },
      "groups_uid" : "-L9Q5d3T_XBBQGJygGqJ",
      "name" : "Sample 1 ",
      "number" : "1234567890",
    }

orderByChild("groups_uid").equalTo("-L9Q5d3T_XBBQGJygGqJ") works

But how to query orderByChild("groups").equalTo("-L9Q5d3T_XBBQGJygGqJ") doesn't work.

Now I wanted to query like: Get all the objects having groups/{some id}/group_id = some value.

I need the objects the one I posted from array which matches groups/{some_id}

Can anyone help me with this query?

You should do something like :

Query query = firebaseServices.getUserData();

query.orderByChild("groups/-L9Q5d3T_XBBQGJygGqJ/group_id").equalTo(groupWiseModel.getId())
