How to downgrade to Android 6.0?
At the same time that there are no errors?
I can not understand how to do it correctly.
At the moment I tried, I get errors on the drawable23

My Manifest.xml https://pastebin.com/9pYYewWK

In your configuration you can see the line

minSdkVersion 17

So your app is targeted for Android 4.2

For sure it will work on 5 and 6.

You can read more details about it here:
