您需要在Bundle参数中添加您朋友的Facebook ID。

params.putString("to", uid);

Answer 2

private void sendInviteDialog(String uid,final int position) {
    Bundle params = new Bundle();
    params.putString("to", uid); 
    params.putString("message", "Please try my app"); 
    WebDialog requestsDialog = (
        new WebDialog.RequestsDialogBuilder(getActivity(),
            Session.getActiveSession(),
            params))
            .setOnCompleteListener(new OnCompleteListener() {
                @Override
                public void onComplete(Bundle values,FacebookException error) {
                    if (error != null) {
                        if (error instanceof FacebookOperationCanceledException) {
                            MessageUtil.showMessage( "Request cancelled", true);
                        } else {
                            MessageUtil.showMessage( ResourcesUtil.getString(R.string.network_unavailable), true);
                        }
                    } else {
                        final String requestId = values.getString("request");
                        if (requestId != null) {
                            MessageUtil.showMessage( ResourcesUtil.getString(R.string.friend_request_sent), true);
                        } else {
                            MessageUtil.showMessage(ResourcesUtil.getString(R.string.request_not_successful), true);
                        }
                    }   
                    mProgressDialog.dismiss();
                }

            })
            .build();
    requestsDialog.show();
}

那是因为您的应用程序处于沙盒模式，请禁用沙盒模式。
