我試圖實現應用程序以在android上發送，接收和解析USSD代碼。到目前爲止，我使用http://commandus.com/blog/?p=58上的代碼來獲得此功能。爲了使服務起作用，需要重新啓動手機。這在用戶第一次安裝應用程序時不會出現問題，但是我在模擬器上進行測試時發現，即使這些服務沒有任何新增功能，手機也需要在每次更新時重新啓動。 什麼，我想知道的是以下幾點：實施USSD功能。將服務綁定到PhoneUtils而不必在每次更新時重新啓動手機
- 那裏可能離開讓PhoneUtils綁定到我的服務，而無需重新啓動？至少在更新時間？
- 如果沒有辦法這樣做，我正在考慮創建2個應用程序，一個是用戶將與之交互的普通應用程序，另一個是包含我的服務的單獨應用程序。在這種情況下，如果用戶需要任何ussd功能，則會在第一次運行時提示用戶安裝第二個應用程序。我很擔心，但這對用戶來說很煩人。你認爲什麼是解決這種方法的最佳方法？
作爲參考，我已經包含了我用於服務的代碼，因爲界面部分不同於在原始網站上發佈的代碼。

謝謝
Android提供的USSD沒有API。去年，我們做了一個跟蹤用戶呼叫和消息的項目。我們到達解析USSD消息。如果你想購買解決方案，我們將討論。 –
嗨Abdennour，你的方法是否允許ussd API無需重新啓動？還有反射嗎？ （只是想知道它是多麼穩定......如果它不是我感興趣:) – vach
https://play.google.com/store/apps/details?id=name.pilgr.android.pibalance&hl=en https://play.google.com/store/apps/details?id=sk.paco.ussd&hl=zh-CN 這兩個應用程序會抑制USSD響應並讀取內容。不知道他們是如何做到的。 – in3xes
