How to perfom query SQL IN clause in Firebase Android
<p>How do I query SQL IN clause in Firebase Android? I want to use it in a Firebase Recycler adapter to retrieve only some children based on some condition. Something like the following statement:</p>

<pre><code>SQL----&gt; select * from posts where city in(10 cities comes here)
</code></pre>
