Android NoClassDefFoundError on android 4.4.2

When I try to run my app on Android 4.4.2 it is giving me this error:

E/AndroidRuntime: FATAL EXCEPTION: main

However, for Android 5.0 and above it is working without any errors.

What is the reason and how can I fix it?

Note: there is a similar question on StackOverflow but it does not have any answers.

Just go to disable Instant Run Go to

File -> Settings -> Build,Execution, Deployment -> Instant Run -> Uncheck the checkbox for instant run

Run your app once.
