How is it a downgrade if I want to upgrade my app to 2.3.7+1 from 2.3.6+2?

I have my app installed on the device with version 2.3.6+2.

I created the new version of it: 2.3.7+1.

And it says I can downgrade the app if I want instead upgrade…?

What could be the problem?

>Solution :

Did you increase the versionCode as well as that versionName you showed?

See https://developer.android.com/studio/publish/versioning

The versionName has no purpose other than to be displayed to users.
