在罐子库的Andr​​oid文件访问时使用Unity使用不 [英] Android files in jar library not accessible when using with Unity

问题描述

我是新来统一。我有我也想作为提供使用Unity插件一个Android库JAR。

I am new to Unity. I have an Android library jar that I want to offer also as a plugin with Unity.

在库jar我有一个包含文件temp.json一个文件夹的HTML。在jar文件（如果我将它解压缩）的结构是这样的： HTML / temp.json （这里请注意，罐子正常工作与团结之外的任何Android应用程序运行时）

Within the library jar I have a folder html which contains a file temp.json. In the jar file (if I unzip it) the structure is like this: html/temp.json (Note here that jar works fine when running with any Android app outside Unity)

这些都是我跟着叫团结，通过我的库中的步骤：

These are the steps that I followed to call my library through Unity:

1）创建的文件夹中的资产/插件/ 的Andr​​oid在我的统一项目层次

1) Created folder Assets/Plugins/ Android in my Unity project hierarchy

2）放在那里我的库jar文件中，沿的Andr​​oidManifest.xml

2) Placed my library jar file there along with AndroidManifest.xml

3）创建一个 bridge.cs ，我用它来调用的函数中的jar文件的文件

3) Created a bridge.cs file that I use to call the functions in the jar file

从罐子函数称为，但库的生命周期我在通话过程罐子在Android侧某处的code内：

Functions from the jar are called, but within the code of the jar somewhere on the Android side during the library lifecycle I call:

InputStream inputStream = MyClass.class.getClassLoader()
.getResourceAsStream("html/temp.json");

和我得到一个ResourceNotFound例外

and I get a ResourceNotFound exception

从我已阅读团结忽略这些文件（如以.json）包装时。因此，从我为了让他们在包装我创建了以下统一的结构时，罐明白了：

From what I have read Unity ignores these files(like .json) when packaging. Therefore from what I understood in order to keep them in the Jar when packaging I created the following Unity structure:

Assets/Plugins/Android/assets/StreamingAssets/html/temp.json

我意识到，被放置在 StreamingAssets中的任何文件文件夹获取库的资产文件夹复制。

I realise that any file that is placed within the StreamingAssets folder get copied in the assets folder of the library.

和Java中我现在请：

and in Java I call now:

inputStream = activity.getResources().getAssets().open("html/temp.json");

不过，我还是得到一个异常，该文件未找到。

However I still get an exception that the file is not found.

任何人都可以请帮我/给我解释一下我所必须遵循的能够同时为Android上统一执行读取在Java端这些文件的程序？

Can anyone please help me/explain to me the procedure I have to follow to be able to read these files on the Java side while executing on Unity for Android?

推荐答案

试试这个code：

    private void readJson() {
    String json = null;
            try {

                InputStream is = getAssets().open("html/temp.json");

                int size = is.available();

                byte[] buffer = new byte[size];

                is.read(buffer);

                is.close();

                json = new String(buffer, "UTF-8");


            } catch (IOException ex) {
                ex.printStackTrace();
            }
    }

和您的JSON文件保存到：

And save your json file to:

Assets/Plugins/Android/assets/html/temp.json

如果您仍然无法做到这一点，PLZ与我联系

If you still can not do it, plz contact me
