CardView Dependency Linking Failure

Question

I want to display a dialog box to display a message along with two buttons (SignIn and Close). But it's giving me a Resource Linking Failed error. though I have a dependency of cardview in my build gradle file (app). Application runs with zero errors but build is failing. 

Here are the different ways I tried to sync it:

implementation 'com.android.support:cardview-v7:+'
implementation 'com.android.support:cardview-v7:28.0.0-alpha3'
compile 'com.android.support:cardview-v7:28.0.0'

Here are the errors in Event Log: 9:25 AM Emulator: emulator: WARNING: UpdateCheck: Failure: Error

9:26 AM Gradle build failed in 1 m 15 s 453 ms

9:26 AM Emulator: emulator: WARNING: AsyncSocketServer.cpp:99: Error when accepting host connectionError message: Unknown error
