Answer 1

I fixed this issue by selecting

API 27+: Android API 27, P preview (Preview)

in the project structure settings. Following image shows my setting. The 13 errors that were coming while building the app, have disappeared.

Answer 2

set your compileSdkVersion 28 let android studio download platform files

Answer 3

if in your app level gradle if you have used compileSdkVersion = 27 then it will not work. You have to use version 28.

compileSdkVersion 28 buildToolsVersion '28.0.3'

Answer 4

Change the line compile 'com.android.support:design:+' to compile 'com.android.support:design:26.+'

The gradle dependencies when the project is built is pulling down the latest versions since the + was telling it "get the latest version." the 26.+ will tell the build process to only update the latest version of v26.

Or to be even more specific and safe, change the line to a specific version, avoiding the + altogether. i.e. compile 'com.android.support:design:27.1.0'
