I want to add this dependency in my build.gradle file :

implementation 'com.android.support:design:28.0.0'

when I add this and click on the Sync now, it gives me error :

Failed to resolve: recyclerview-v7

and this is my build.gradle file :

// Top-level build file where you can add configuration options common to 

all sub-projects/modules.

buildscript 
 repositories 
 google()
 jcenter()
 
 dependencies 
 classpath 'com.android.tools.build:gradle:3.2.1'

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


allprojects 
 repositories 
 google()
 jcenter()
 mavenCentral()
 mavenLocal()
 


apply plugin: 'com.android.library'

android

I know that in my observablescrollview library, there is recyclerview dependency, but I don't know why i get this error.

I searched every where and none of solutions worked. Solutions like changing order of google() and jcenter() repositories ...

You get this error because observablescrollview uses uses implementation to reference the recyclerview. This new build keyword makes inner dependencies invisible for you. In most cases, you do not need them anyways.

in your case:
if you want to use them, you need to contact the authors to compile with api instead of implementation for the recyclerview reference.

If they don't do that, you have no chance to use their inner dependency.
