Google Maps API on android not working

Question

I am trying to add a map to my android application.
But I am getting the error posted below.

I have installed the google play services, and have also added
the required dependency for my app to support map.

I have added the required api key to the manifest,
added the following line after the application tag

uses-library android:required="true"
android:name="com.google.android.gms"

(the following in an element of the application tag and not an attribute)
An idea what I am doing wrong?

Answer 1

so I cracked this question a few days ago and here is how I made it work. I removed all traces of the google play library in the projects sections. Next I re-imported the google play library but this time I clicked the option for copying it into my workspace as well. Next in the added this library in the compile paths and it worked.
