Do I need Gradle dependency for RecyclerView?

Question

I forgot to include this in Gradle -

compile 'com.android.support:recyclerview-v7:23.+'

But my project works fine without this record. So, why do I need to write it in Gradle? Can I use only appcompat?

compile 'com.android.support:appcompat-v7:23.2.0'

Answer 1

com.android.support:appcompat-v7 does not depend on com.android.support:recyclerview-v7, but com.android.support:design does.

There's no harm in including this dependency one more time in your build.gradle, but it's not necessary since design includes it.
