title: Volley Library on Android9
body: <p>Volley library is used in the Android app we are developing.However, the following error has occurred in Android9.</p>
  
  <pre><code>java.lang.NoClassDefFoundError: 
  at com.android.volley.toolbox.HurlStack.performRequest (HurlStack.java:108)
  at com.android.volley.toolbox.BasicNetwork.performRequest (BasicNetwork.java:96)
  at com.android.volley.NetworkDispatcher.run (NetworkDispatcher.java:112)
  </code></pre>
  
  <p>Since Apache HTTP Legacy library is not available on Android9, the following code is inserted in AndroidManifest.xml, but the error is not resolved.</p>
  
  <pre><code>&lt;application
      &lt;uses-library
          android:name="org.apache.http.legacy"
          android:required="false" /&gt;
  &lt;/application&gt;
  </code></pre>
  
  <p>Could you tell me how to solve this problem?</p>
