title: Android Firebase multiple sort
body: <p>I have a question about firebase sorting.</p>
  
  <p>I have the next database:</p>
  
  <pre><code>{
      "-Ka8xxTgyFB8yYKH50j_addclose" : {
          "number" : 0,
          "point" : 949739,
          "timestamp" : 14824078463440,
          "username" : "Test 16062"
      },
      "-Ka8xzKecpbPr46Kx9gl" : {
          "number" : 0,
          "point" : 1480851,
          "timestamp" : 14842078463441,
          "username" : "Test 13599"
      }
  }
  </code></pre>
  
  <p>I want to display data sorted by point.
  But i need rows only which created today. </p>
  
  <p>If i filter the rows for timestamp:</p>
  
  <pre><code>return databaseReference
                  .child("list")
                  .orderByChild("timestamp")
                  .endAt(end.getTime());
  </code></pre>
  
  <p>The <code>endAt</code> is work good. Only todays rows listed.
  But... Now i need to sort by <code>point</code>. </p>
  
  <p>How can i do it? </p>
  
  <p>There is any idea to change database or sort my list on clientside?</p>
  
  <p>Thanks so much!</p>
