问题
I am bit confused about use case of
com.google.android.gms:play-services-base:8.4.0
From the play service documents it says this is for Google Actions, Base Client Library
Questions are:-
1) Use case for this Particular Service?
2) If it is base client Service, Does that means if we have already added this library we wont need to add any sub library/service like location?
Edit:- Corrected Service name
回答1:
it says this is for Google Actions, Base Client Library
No, it does not. That is GCM, Google Cloud Messaging. com.google.android.gms:play-services-base is "Google Actions, Base Client Library".
I am going to assume that you really meant play-services-base, not play-services-gcm, given your title.
Use case for this Particular Service?
It is used internally by other specific Play Services dependencies. I am not aware of any place where you would use this yourself directly, though Play Services is vast and I may be missing something.
Does that means if we have already added this library we wont need to add any sub library/service like location?
No. Instead, if you have a dependency on something else (e.g., play-services-gcm), it will probably pull in play-services-base for common code.
