I cannot use Instant Run in Android Studio
<p>I follow the guide on <a href="http://tools.android.com/recent/androidstudio20preview9available" rel="nofollow">http://tools.android.com/recent/androidstudio20preview9available</a> to update my Android Studio to the preview version.<br>
And then I try to use Instant Run to run something.
When I open the Run Configures, I see an warning are telling "Instant Run requires a newer version of the Gradle plugin."<br>
And there is a red-font hyperlink "Update Project".</p>

<p>Then I pressed it, and Android Studio give me a message "Error updating to new Gradle version"</p>

<p>What should I do if you want to use the Instant Run?</p>
