android - USSD 服务不工作

Question

我正在尝试开发一个应用程序，它会默默地忽略 USSD 响应。我使用了 http://commandus.com/blog/?p=58 中的代码有微小的变化。我在包 com.android.internal.telephony 和包 com.commandus 内的 USSDDumbExtendedNetworkService 中创建了 IExtendedNetworkService.aidl .ussd。问题是，运行应用程序后没有任何反应(即使在重新启动手机后)。有人可以指出我做错了什么吗？我应该编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();
}

您是否在 list 文件中声明了广播接收器？

在 list 中添加:

<receiver android:name="com.xxx.receivers.BootReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

<service android:name="your.package.ExtendedNetworkService" />

在 BootReceiver.java 中:

    public void onReceive(Context context, Intent intent) {

        context.startService(new Intent(context,ExtendedNetworkService.class));
}

在 ExtendedNetworkService.java 中:

public class ExtendedNetworkService extends Service {

    IExtendedNetworkService.Stub binder = new IExtendedNetworkService.Stub() {

        public void setMmiString(String number) throws RemoteException {}
        public CharSequence getMmiRunningText() throws RemoteException {

            return null;
        }
        public CharSequence getUserMessage(CharSequence text)
                throws RemoteException {

            Log.d(Constants.TAG, "Message : " + text);
            Log.d(Constants.TAG, "getMmiRunningTest() : " + getMmiRunningText());
                return null;
        }
        public void clearMmiString() throws RemoteException {
        }

    };

        return false;
    }

    public void onCreate() {

        Log.d(Constants.TAG, "ExtendedNetworkService Started..");

        super.onCreate();
    }

public IBinder onBind(Intent arg0) {

        Log.d(Constants.TAG, "ExtendedNetworkService got binded...");

        return binder;

    }

}
