no changes to deploy android studio 2.1

The question:

Android Studio 2.1 instant run is not updating the app on the device

I observed an issue with AndroidStudio 2.1. When I run the app with small java code changes, it doesn’t update app on the device sometimes. Instead it shows a message

No changes to deploy // (Don’t show again)

Am I missing any thing here?
As a work around I do clean build every time in order to reflect the changes in app.

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

Upgrade Android studio version to 3 or more. this bug is resolved.

This was a bug on version 2.0 instant run and issues were reported check these links

thing to do would be to disable Instant Run entirely by

Settings > Build, Execution, Deployment > Instant Run > Enable
Instant Run

You can file a bug at this link: Google Issue Tracker

please check this answer to turn it off.

Method 2

Thats a bug in Android Studio, I noticed it in build 2.0 sometimes it failed to update, so what i do is I rebuild the entire project, one more thing, if you have multidex enabled and your device is not running 5 <it will not work, make sure its disabled and rebuild your project.

Method 3

I have just noticed that whenever i closed my app and then run it worked. See my post here.
