title: how to check whether file exists or not using content uri
body: <p>I have a content uri of an audio file, which I got it from chooser intent.</p>
  <pre><code>content://com.mi.android.globalFileexplorer.myprovider/external_files/KannadaGeeta/11CHAPTER10.mp3
  </code></pre>
  <p>I just saved the above uri on database.</p>
  <p>Now, when user opens my app again. I need to inform him whether the last mp3 file which he selected exists or not. If exists then only I must allow him to continue else I need to inform to download the file again.</p>

  <p>Kindly, help me to solve my issue.</p>
