Does the method from the performPosting example not post?

Question

Android

Hello. I'm trying to make a post on the wall from an android application, I make a post as shown in the example
mOdnoklassniki.performPosting("{\"media\":[{\"type\":\"text\",\"text\":\"hello world!\"}]}",
false, null, new OkListener() {
@Override
public void onSuccess(final JSONObject json) {
Log.e("POST OK", json.toString());
}
@Override
public void onError(String error) {
Log.e("POST OK", "error = " + error);
}
});
The method returns E/POST OK: {"id":"0","type":"success","signature":"5dbd406a82862fac760a5a032598503a"}
But I can't find where this post goes, it's not in the feed. Tell me please
