I have set up my project's minSdkVersion as 15 and enabled Instant Run .
I have deployed the app in my device running on API 21 But the "Apply Changes" button is grayed out.When I hover over the button it says "No Active 'App' launch" although I am running the app in my device at that time .

According to the guide, you also need to choose the debug build variant.

To start using Instant Run, you also need to change the build variant to a debug version of your app and deploy it to a target device running Android 5.0 (API level 21) or higher.

By default, Instant Run is disable when you first install Android Studio. So you need to enable it by following this path :- File/Settings/Build, Execution, Deployment/InstantRun and checked the Enable InstantRun check box.
