Okay Finally Got the Answer.

abcd = ref.orderByChild('message').equalTo(msg);
abcd.on('value', function(abcdSnap){
    var a = abcdSnap.val();
    var b = Object.keys(a)[0];
    ref.child(b).remove();
})

public void removeUserData()
{
    databaseReferenceC = FirebaseDatabase.getInstance().getReference("users/profiles/");
    FirebaseUser user = firebaseAuth.getCurrentUser();
    databaseReferenceC.child(user.getUid()).removeValue();
}

as a example you can use something like that use removeValue()
