Excuse me, I want to try facebook developer for android Tutorial. at Show Friends part. I have succeed doing Step hello Scrumptious, Autenticate with login and personalize part. At Show Friends part, I get error
The method getRequestCode() is undefined for the type SelectionFragment
I use API level 17 before. Then try to change to API Level 10, I get many errors. And I change to API Level 8, then, the previous error appears. getRequestCode() method is still not working.
Can You help me to give any clue error? I have try to search at internet but, really I do not know what is the problem. I try to re-read the tutorial, make new project, and trying then still fails for many times.
Please help.
Thank You.
