It looks like you can't create an activity using REST and OAuth. I'm encountering a similar issue as mentioned here - http://code.google.com/p/opensocial-java-client/issues/detail?id=32#c0
When creating an activity via REST, I'm always getting this error: "Only activities for the current application can be accessed or modified". Can anyone confirm this? Any possible solutions? -- You received this message because you are subscribed to the Google Groups "orkut Developer Forum" group.
