App won't run under Android Studio 2.0, after upgrading from 1.5
<p>I recently upgraded my Android Studio from 1.5 to 2.0. My app would build and run nicely on Android 1.5. Now, when I try run the app on my smartphone, it gives me this error: </p>

<pre><code>Error:Execution failed for task ':app:transformClassesWithInstantRunForDebug'.
&gt; 24
</code></pre>

<p>When opening my project on Android Studio 2.0, a message box appeared, telling me to upgrade my gradle to version 2, which I did. I am not sure why I am getting this error. </p>

<p>Here is the output I get as I try to run the app on my phone: </p>
