如何添加使用Qt的Android扩展文件 [英] How to add android expansion files using Qt
问题描述
我目前正在开发使用Qt / QML和我的应用程序将超过50 MB谷歌Play商店限制大了很多Android应用，由于是被捆绑的媒体文件，所以我必须使用扩展名的文件。经过一番搜索我一个页上行说，Qt的资源系统可以帮助.obb扩展名的文件：
I am currently developing an Android app using Qt / QML and my app will be a lot larger than the 50 MB Google Play Store limit due to media files that are to be bundled, so I have to use extension files. After some searching I found on a page a line saying that Qt resource system can help make .obb extension files:
对于不适合入谷歌Play商店50 MB的限制，QRC可以生成放在OBB文件RCC大资源
"For large resources that do not fit into the Google Play store 50 MB limit, qrc can generate rcc files that can be put in obb"
但我无法找到如何做到这一点的任何信息或如何从我的code访问这些文件。
but I can not find any information on how to do this or how to access those files from my code.
编辑：
我已经使用Qt做出了.rcc文件。试图将其转换现在.obb。此人使用JOBB工具来完成？
I have made an .rcc file using Qt. Trying to convert it to .obb now. Anyone done this using the jobb tool?
我也在想，我可以上传文件.rcc直接作为谷歌播放接受扩展文件的文件格式，但后来我将无法得到它加密的..但我怎么能访问.rcc文件？我必须写一些Java code或我能得到它从Qt的C ++ / QML工作？
I was also thinking that I could just upload the .rcc file directly as Google Play accepts any file format for expansion files, but then I would not be able to get it encrypted.. but how could I access the .rcc file? Do I have to write some Java code or could I get it to work from Qt C++/QML?
编辑：
我想到了。我使用Qt的命令提示符下可用的RCC工具创建一个外部二进制资源文件。使用QResource类我可以加载外部的二进制资源文件和访问它，因为它是一个正常的QRC资源文件。
I figured it out. I created an external binary resource file using the rcc tool available in Qt command prompt. Using QResource class I can load the external binary resource file and access it as it was a normal qrc resource file.
推荐答案
我面临着扩展文件类似的问题并解决它。虽然我没有覆盖任何加密的问题。
I was facing a similar issue with expansion files and solved it. Although I did not cover any encryption issues.
