body: <p>Instant Run is a new feature introduced for reduce time for run and debug app.
  I have all the required configuration for enabling Instant run, but it is not enabled on Android Studio. Here is my configuration below.</p>
  
  <pre><code>1. Android Studio 2.1
  2. 'com.android.tools.build:gradle:2.1.0'
  3. minSdkVersion 15
  4. Settings-&gt;Build, Execution, Deployment &gt; Instant Run = "Enable Instant Run..."
  5. Run -&gt;device is  Android version 4.4.4
  </code></pre>
  
  <p>Then Instant Run is NOT enabled. <a href="https://i.stack.imgur.com/mR6aL.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mR6aL.png" alt="enter image description here"></a></p>
