Adding dependencies to Google play service and Google+ sign in

Question

I actually have the next dependencies in my gradle file:

compile 'com.google.android.gms:play-services-auth:8.4.0'
compile 'com.google.android.gms:play-services:8.4.0'

When I added the last (needed to implement GCM) I got errors, and now I need to use multidex for debugging.

My question is if the first library is redundant.

Thanks in advance.

I am already using multidex, but when I try to debug in my device, the app is installed with a gray icon that says _App_. — JCarlosR, Feb 04 '16 at 05:27

did you syn files after adding dependencies in build.gradle i.e. a cream colored bar appearing on top saving Gradle files have changed since last project....click on that to syn your new dependencies....

Yes, I did that. I am just asking if the first dependency is necessary when I am using the second. – JCarlosR Feb 04 '16 at 06:11

Using the next dependency

compile 'com.google.android.gms:play-services:8.4.0'

It is not necessary to use the particular dependency for authentication with Google+

compile 'com.google.android.gms:play-services-auth:8.4.0'

And finally, I don't need to use multidex when I add my dependencies exactly

compile 'com.google.android.gms:play-services-auth:8.4.0'
compile 'com.google.android.gms:play-services-gcm:8.4.0'

I found this information in the section Selectively compiling APIs into your executable.

Thank you.
