Answer 1

Restart Android Studio and the message should be shown again. You can also do it from Android SDK. Go to tools-> Android-> SDK Manager. There you can install everything you need. If you need more details about what is already installed, check show details checkbox.

Answer 2

Update your android gradle plugin to 3.0.1 . In your project level build.gradle

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

Go to your module level build.gradle file and remove the line that says

buildToolsVersion '26.0.2'

It will automatically use a minimum default.
