I have below firebase database structure. I an trying to query m_no
which is nested under a dynamically created arraylist
below is the code i have tried but it is not working.Any idea how to query this?
mReferenceBooks=mDataBase.getReference("book").child("dMoble");
mReferenceBooks.orderByChild("m_no").equalTo(emailID).addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
}

The query wont work because above the dMoble
, you have the random id. Therefore you need to access that id
and add it as a child()
to be able to query:
mReferenceBooks=mDataBase.getReference("book").child("-Ly3FuE6GF-oExG2puhj").child("dMoble");
