show picasa album in android app

I want to show picasa album in a grid view in my android app. I have the username/password + album id of the album from which i want to load the album.

i tried implementing this via gdata library but eclipse is giving an err开发者_如何学编程or on line2 in following syntax:

PicasawebService myService = new PicasawebService("exampleCo-exampleApp-1");
myService.setUserCredentials("liz@gmail.com", "mypassword");

I have also added gdata libraries in my code. Following are the names:

gdata-photos-2.0
gdata-client-1.0

Any idea what i am doing wrong? OR Please suggest any tutorials who has implemented this.

Please help!!
