Android :: Attach A Bitmap When Launching ACTION_SEND Intend?

I have this code: Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND); startActivity(intent);

which successfully launch an Messaging App on android.

But how can i attach a Bitmap object when launching the intent?

I have read http://developer.android.com/reference/android/content/Intent.html, the closet thing to what i need is EXTRA_STREAM, like this: intent2.putExtra(Intent.EXTRA_STREAM, _uri);

but my case, I have a reference of Bitmap object, not an URI of an Bitmap.

Please tell me what can I do to attach a Bitmap object?
