cannot resolve floatinbuttonAction and snackbar

Question

I'm very new to the android development. I imported my friend's project in my android studio and I'm having this trouble right now that I'm unable to sort out on my own. Please help me fix it.

Answer 1

Package android.support.design.widget.FloatingActionButton and android.support.design.widget.Snackbar lies under design-support library. You have to add design-support library into your project.

Add below dependencies into your app modules build.gradle file and Sync .

dependencies {
    ............
    ................

    compile 'com.android.support:design:25.3.1'
}

Hope this will help
