我正在尝试开发一个静默地忽略USSD响应的应用程序。我使用了http://commandus.com/blog/?p=58中的代码,但做了一些小改动。我已经在com.android.internal.telephony包中创建了IExtendedNetworkService.aidl,并在com.commandus.ussd包中创建了USSDDumbExtendedNetworkService。问题是,在运行应用程序后没有任何反应(即使在重启手机之后)。有人能指出我做错了什么吗?我应该写任何额外的代码来使它工作吗?

IExtendedNetworkService.aidl

package com.android.internal.telephony;

/**
*  Interface used to interact with extended MMI/USSD network service.
*/
interface IExtendedNetworkService {
 /**
 * 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);

/**
 * return the specific string which is used to prompt MMI/USSD is running
 */
CharSequence getMmiRunningText();

/**
 * Get specific message which should be displayed on pop-up dialog.
 * @param text original MMI/USSD message response from framework
 * @return specific user message correspond to text. null stands for no pop-up dialog need to show.
 */
CharSequence getUserMessage(CharSequence text);

/**
 * Clear timeout message and pre-set MMI/USSD command
 * This should be called when user cancel a pre-dialed MMI command.
 */
void clearMmiString();
}

USSDDumbExtendedNetworkService
