Java 在Android中使用IExtendedNetworkService获取USSD响应

我正试图找到在Android中发出USSD请求的方法。我找到了这个-。 我将所有需要的文件添加到我的项目中

ussdumbExtendedNetworkService.java：

package com.android.ussdcodes;

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.net.Uri;
import android.os.IBinder;
import android.os.PatternMatcher;
import android.os.RemoteException;
import android.util.Log;

import com.android.internal.telephony.IExtendedNetworkService;
import com.android.ussdcodes.R;

/**
 * Service implements IExtendedNetworkService interface. 
 * USSDDumbExtendedNetworkService
 * Service must have name "com.android.ussd.IExtendedNetworkService" of the intent declared
 * in the Android manifest file so com.android.phone.PhoneUtils class bind
 * to this service after system rebooted.
 * Please note service is loaded after system reboot! 
 * Your application must check is system rebooted. 
 * @see Util#syslogHasLine(String, String, String, boolean)

}

舱单：

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

        <service
            android:name=".USSDDumbExtendedNetworkService" >
            <intent-filter android:icon="@drawable/ic_launcher">
                <action android:name="com.android.ussd.IExtendedNetworkService" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </service>

现在，服务在引导完成后启动

我的问题是如何发送USSD请求并获得服务响应？

---

谢谢

我找到了答案

我只是把它放进去

停用消息

USSDDumbExtendedNetworkService.mActive = false;

发送USSD：

Intent launchCall = new Intent(Intent.ACTION_CALL,
                        Uri.parse("tel:" + Uri.encode(ussdcode)));
launchCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
launchCall.addFlags(Intent.FLAG_FROM_BACKGROUND);
startActivity(launchCall);

再次激活消息

USSDDumbExtendedNetworkService.mActive = true;
USSDDumbExtendedNetworkService.mRetVal = null;

你能知道怎么做吗？我也在找同样的东西：（

com.android.internal.telephony.IExtendedNetworkService；

无法解析。您能告诉我您的sdk最低版本是什么吗？您是否已将com.android.internal.telephony包添加到IExtendedNetworkService.aidl中，正如本教程在问题开头所述。（）好的，我解决了它…

.aidl

不在我指定的目录中。现在我如何从活动中调用USSD？提前谢谢。您在哪个版本的android上测试过它？我一直在努力使这个示例工作，但没有任何结果。然后我发现我已经在4.1上测试过它。1@Arhimed：您是如何解决此问题的？请提供正确答案代码在这里，因为我正在寻找它solution@arhimed请提供工作解决方案或代码，以创建其他步骤

USSDDumbExtendedNetworkService.mActive = true;
USSDDumbExtendedNetworkService.mRetVal = null;
