Gradle error while adding the dependencies CardView and RecylerView

Question

I am trying to implement a cardView, where when the user presses the FAB, a cardView is created dynamically. However, when I put the following bit of code in the gradle dependencies, I get an error:

implementation 'com.android.support:cardview-v7:23.0.+'
implementation 'com.android.support:recyclerview-v7:23.0.+'

It says 'This support library should not use a different version (23) than the compileSdkversion 27.

Currently, my apk level is 16.

What's the problem?

Answer 1

Just replace with this dependency in your Gradle.build:

com.android.support:cardview-v7:27.1.1
com.android.support:recyclerview-v7:27.1.1

Answer 2

Currently, you have used compileSdkversion 27 . So you need to update dependency to 27 .

implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'

Don't try to use + sign for integrating dependency.
