Android Facebook v4.0 Post Image and Text

 JSONObject jsonObject = new JSONObject();
    try {

        jsonObject.put("picture", bitmap);
        jsonObject.put("message","just a message");

    } catch (JSONException e) {
        e.printStackTrace();
    }


    GraphRequest graphRequest = GraphRequest.newPostRequest(AccessToken.getCurrentAccessToken(), "me/photos", jsonObject, new GraphRequest.Callback() {
        @Override
        public void onCompleted(GraphResponse graphResponse) {

            Log.d("", "------ graphResponse = " + graphResponse);

        }
    });


    graphRequest.executeAsync();

And is returning

graphResponse = {Response: responseCode: 400, graphObject: null, error: {HttpStatus: 400, errorCode: 324, errorType: OAuthException, errorMessage: (#324) Requires upload file}}
