推荐答案

您可以在Android设备上运行USSD codeS，但你将无法解析结果在应用程序中。此功能可能被添加到了Android SDK的未来，但现在，你将不得不寻找一个替代品。

You can run USSD codes in Android devices but you would be unable to parse the result in your application. This feature might be added to the Android SDK in the future but for now, you would have to look for an alternative.

USSD可以通过简单的通话意图运行。见例子：

USSD can be run using simple Call intents. See Example:

String ussdCode = "*" + "123" + Uri.encode("#");
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + ussdCode)));

如上述评价电话呼叫许可也是必需

as mentioned in the comments phone call permission is also required

<uses-permission android:name="android.permission.CALL_PHONE" /
