Getting Errors on the working code after adding appcompat_v7 library

Question

The code was working fine before adding action bar in project. The added library is **appcompat_v7**. After adding action bar the following problems occurred

Code:

private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

Error:
NetHttpTransport cannot be resolved to a type.
HttpTransport cannot be resolved to a type

Code:

@Key
public String id;

Error: Key cannot be resolved to a type

I think the error happened because the imports are not working. The imports are

com.google.api.client.googleapis.GoogleHeaders;
com.google.api.client.http.GenericUrl;
com.google.api.client.http.HttpRequest;
com.google.api.client.http.HttpRequestFactory;
com.google.api.client.http.HttpRequestInitializer;
com.google.api.client.http.HttpTransport;
com.google.api.client.http.javanet.NetHttpTransport;
com.google.api.client.http.json.JsonHttpParser;
com.google.api.client.json.jackson.JacksonFactory;

com.google.api.client.util.Key;
