Question

I’m using facebook-android-sdk to post messages to my wall.

The following request:

Bundle params = new Bundle();

params.putString("message", "test message");

mAsyncRunner = new AsyncFacebookRunner(mFacebook);
mAsyncRunner.request("me/feed", params, "POST", new PostRequestListener(), null);  

returns the warnings shown below, although the message is shown correctly on the wall.

When converting the message to bytes, as seen in similar questions on Stackoverflow:

params.putByteArray("message", "test message".Bytes());

there is no more warnings for Key message, and the post is shown on the Facebook wall, but with no message.

What’s wrong?

Thanks.
