How implements a jar library in ANE Project?

Hello

I´m trying use android.support.v7, I import all resources and jar but i cant reach the Library in my project what is happening?

Reasons to use this library:

AlertDialog with the material theme

I need understand better how include library and resources and what add in mainifest additions in app xml

I included in another project the GooglePlayServices but is very very old , but when i try update nothing works looks all the library is different, the mainifest additions don´t work how proceed also?
