USSD の応答を黙って却下するアプリケーションを開発しようとしています。http://commandus.com/blog/?p=58のコードを少し変更して使用しました。IExtendedNetworkService.aidlパッケージ内com.android.internal.telephonyとUSSDDumbExtendedNetworkServiceパッケージ内に を作成しましたcom.commandus.ussd。問題は、アプリケーションを実行した後 (電話を再起動した後でも) 何も起こらないことです。誰かが私が間違っていることを指摘できますか? 動作させるために追加のコードを書く必要がありますか?

/**
* Set a MMI/USSD command to ExtendedNetworkService for further process.
* This should be called when a MMI command is placed from panel.
* @param number the dialed MMI/USSD number.
*/
void setMmiString(String number);
/**

*/
CharSequence getMmiRunningText();
/**
