带有Qt的Android应用程序的Necessitas SDK
[英]Necessitas SDK for android app with Qt
问题描述
There are 2 pages that confuse me: 
有2页让我感到困惑：
http://doc.qt.io/qt-5/android-support.html http://doc.qt.io/qt-5/android-support.html
and 和
https://wiki.qt.io/How_to_Create_and_Run_Qt_Application_for_Android https://wiki.qt.io/How_to_Create_and_Run_Qt_Application_for_Android
Both these pages guide you on how to create Android apps with Qt. 这两个页面均指导您如何使用Qt创建Android应用。 But one uses the Necessitas SDK and the other doesn't. 但是一个使用Necessitas SDK，而另一个则不使用。
I want my app to use the Google-Cloud-Messaging service to be able to send and receive notifications. 我希望我的应用能够使用Google云消息服务来发送和接收通知。
I already have created an Android app and it runs fine on my phone without using the Necessitas SDK. 我已经创建了一个Android应用，并且可以在手机上正常运行，而无需使用Necessitas SDK。
So my question is: Do i need this necessitas SDK? 所以我的问题是：我需要这个必需的SDK吗？ if so, why? 如果是这样，为什么？ Or can i just continue like i already have? 还是我可以像以前一样继续前进？

I think the 2nd link is out of date. 我认为第二个链接已过期。 From what I understand, necessitas was needed for Qt4 but Qt5 has it by default. 据我了解，Qt4需要necessitas，但Qt5默认情况下具有它。
