Android studio 2.0 bug:no changes to deploy
<p>I download the latest Android Studio 2.0 from Android Develop Website.</p>

<p>But when I change a line of code and use the "instant run", instead of updating the changes, it prompt me "<strong>no changes to deploy</strong>".</p>

<p>This will happen on code changes and XML changes.</p>

<p>But when I restart Android Studio, things will works fine for once or twice and then "<strong>no changes to deploy</strong>" Come again!</p>

<p>I used my old SDK on Android Studio older version.
JDK is 1.7.0
Windows7 64</p>

<p>So, is anyone has this same bug?</p>
