如何在Android上执行USSD请求？

Question

一些自定义拨号器应用程序(例如,来自MotoBlur的拨号器)能够执行USSD请求.通过SDK实现这一点真的不可能吗？

Answer 1

您可以拨打任何其他号码的ussd请求,其呼叫意图如下:

String encodedHash = Uri.encode("#");
String ussd = "*" + encodedHash + "12345" + encodedHash;
startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)), 1);

但是,afaik,目前无法在您的应用中解析结果字符串.

Answer 2

您可以拦截USSD响应,为此,您需要实现IExtendedNetworkService.aidl接口,该接口将服务与PhoneUtils绑定.然后它可以拦截任何USSD响应,您可以轻松地在应用程序中阅读.仅供参考 https://github.com/alaasalman/ussdinterceptor

在 API26 中添加了 ussd api。所以因为奥利奥和 ussd 一起工作看起来像这样：

    TelephonyManager manager = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
    manager.sendUssdRequest("*100#", new TelephonyManager.UssdResponseCallback() {
        @Override
        public void onReceiveUssdResponse(TelephonyManager telephonyManager, String request, CharSequence response) {
            super.onReceiveUssdResponse(telephonyManager, request, response);
        }

        @Override
        public void onReceiveUssdResponseFailed(TelephonyManager telephonyManager, String request, int failureCode) {
            super.onReceiveUssdResponseFailed(telephonyManager, request, failureCode);
        }
    }, new Handler());

    TelephonyManager manager2 = manager.createForSubscriptionId(subIdForSecondSlotFromSubscriptonManager);
    manager2.sendUssdRequest(...);

要获取 simID，您可以使用以下命令：

    SubscriptionManager subscriptionManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);

    List<SubscriptionInfo> subscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();

    for (SubscriptionInfo subscriptionInfo : subscriptionInfoList) {
        int subscriptionId = subscriptionInfo.getSubscriptionId();
        Log.d("Sims", "subscriptionId:" + subscriptionId);
    }

    if (subscriptionInfoList != null) {
        if (subscriptionInfoList.size() == 1) {
            sim1 = subscriptionInfoList.get(0).getDisplayName().toString();
            tvSim1.setText(sim1);
        } else {
            sim1 = subscriptionInfoList.get(0).getDisplayName().toString();
            sim2 = subscriptionInfoList.get(1).getDisplayName().toString();

            tvSim1.setText(sim1);
            tvSim2.setText(sim2);
        }

    }

从 Android O 开始，可以使用TelephonyManager.
