title: How do I install Android SDK Platform-Tools 24.0.0?
body: <p>I'm following the guide for setting up the Android N Preview <a href="https://developer.android.com/preview/setup-sdk.html" rel="noreferrer">https://developer.android.com/preview/setup-sdk.html</a></p>
  
  <p>In "Update or Create a Project" Google says I need to have 24.0.0 platform tools.</p>
  
  <blockquote>
    <p>Just be sure that you've updated your project to use Android SDK Build
    Tools 24.0.0 and Android SDK Platform-Tools 24.0.0.</p>
  </blockquote>
  
  <p>I have installed the new SDK Platform: Android 6.X (N), API Level 24, Revision 1. However when I open SDK Tools the only Android SDK Platform-Tools version is 23.1. </p>

  <p>I have updated my <code>build.gradle</code> for Android 24 and for Jack and Java 8 (<a href="https://developer.android.com/preview/j8-jack.html" rel="noreferrer">see</a>).</p>
  
  <p>Everything works great on Android 24 simulator but crashes on a device or simulator running Android 22/23 (less than 24) with the following error:</p>
  
  <blockquote>
    <p>java.lang.NoSuchMethodError: No virtual method
    stream()Ljava/util/stream/Stream; in class Ljava/util/ArrayList; or
    its super classes (declaration of 'java.util.ArrayList' appears in
    /system/framework/core-libart.jar)</p>
  </blockquote>
  
  <p>I suspect the cause is having SDK Platform-Tools version 23.1.0 instead of 24.0.0 but if there is another solution i'd be happy to hear it.</p>
  
  <h2>Edit</h2>
  
  <p>Installing platform tools 24.0.0 rc1 did not fix the crash.
  I'm not sure what else to try given that I have followed all the instructions to setup the preview and the Jack compiler.</p>
