Multilevel listview - Android Studio
<p>I am working on a school project and making a listView in android studio which will list all the agencies and when i click one agency it must give me all the agent details under that selected row , and when I click on the agent it should give me the contact information of the agent. </p>

<p>I am following this tutorial as a reference: <a href="http://www.androidhive.info/2012/10/android-multilevel-listview-tutorial/" rel="nofollow">here</a>  and I am stuck at point no. 4</p>

<p>I am using android studio and not eclipse(as per this tutorial) so was wondering where to add the .helper package in android studio in order to add AlertDialogManager.java file in it. </p>

<p>I am a newbie in android so any help is appreciated. Thanks!!</p>
