It is impossible to translate your project on V7: 28.0.0. I took and created an empty default project in general that the studio offers to choose from when creating a project. In particular, took Google Maps. Immediately when creating a project, the Minimum API LEVEL 28 pointed out to see how everything will create a studio with automatt. Only after creating a project, immediately an error, line
began to emphasize red. Good, gouglim. I read that you need to connect

prescribed. After the project reversed. Red to emphasize stopped. Only in the default mapsactivity cannot connect
stupidly red. And appropriate, in my project, as well. Only a lot of things can not connect: annotations, etc.
Yes, found that you need to connect:
implementation 'com.android.support:support-annotations:8.0.0' Implementation 'com.android.support:support-v4:28.0.0' Implementation 'com.android.support:support-fragment:28.0.0'
Only this does not help. Where to dig?
If you use AndroidX you need to load and use AndroidX libraries.
