Answer 1

private DatabaseReference dbRef;
ValueEventListener mSendEventListner;

dbRef = FirebaseDatabase.getInstance().getReference().child("users").child(phone);

ValueEventListener valueEventListener = new ValueEventListener() 
{
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                if (dataSnapshot.exists())
                {              
                   //
                } 
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {
                //
            }
};
dbRef.addValueEventListener(valueEventListener);
mSendEventListner = valueEventListener;


//REMOVE VALUE EVENTLISTNER...
@Override
protected void onDestroy() 
{
    super.onDestroy();
    if (mSendEventListner != null) {
        dbRef.removeEventListener(mSendEventListner);
    }
}
