How to download youtube api jar for android

How to download youtube api jar for android

im trying to use youtube api codes but i cant find from where i download
the correct jars.
I got to this page:
https://code.google.com/p/google-api-java-client/wiki/APIs#YouTube_Data_API
I downloaded the file but i got there many jars and on the developers site
its not wrinten which jars i should import.
I trired to import the file called:
google-api-services-youtube-v3-rev77-1.17.0-rc from the root folder but
when i try to use sample code eclipse cant find the imports.
The sample code is here:
https://developers.google.com/youtube/v3/code_samples/java#search_by_keyword
When im trying to use
private static final JsonFactory JSON_FACTORY = new JacksonFactory();
Eclipse cant find from to import the files.
I dont understand why using youtube api should be so complicated. why not
putting all the code on one simple jar.
