目的是为了更好的管理和复用Android SDK或者Android Native。

一.基本目录结构

注意要遵循下面路径结构

根路径为Assets/Plugins/Android/你的模块名/

MyModule

|-------CSharp【用于存放C#代码】

|-------Java【用于存放Java代码】

|-------libs【用于存放jar或者o文件】

|-------你的模块名.androidlib【用于存放模块使用的资源和相关配置】

|--------------assets【等同于Android assets】

|--------------res【等同于Android res】

|--------------AndroidManifest.xml【必须】

|--------------project.properties【必须】

二.测试配置数据 2.1 AndroidManifest配置

Assets/Plugins/Android/MyLibrary/my.androidlib/AndroidManifest.xml

2.2 project.properties配置

Assets/Plugins/Android/MyLibrary/my.androidlib/project.properties

android.library=true

2.3 config.txt

Assets/Plugins/Android/MyLibrary/my.androidlib/assets/config.txt

我是UTF-8配置数据

2.4 AndroidTestClass.java

Assets/Plugins/Android/MyLibrary/Java/AndroidTestClass.java

package cn.katagames.test;

import java.io.InputStream;
import android.app.Activity;

public class AndroidTestClass {
    public static String GetConfig(Activity activity,String fileName)
    {
        String res="";
        try {
            InputStream is = activity.getResources().getAssets().open(fileName);
            int len = is.available();
            byte []buffer = new byte[len];
            is.read(buffer);
            res = new String(buffer, "utf-8");
            is.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return res;
    }
}

2.5 JavaTest.cs

Assets/Plugins/Android/MyLibrary/CSharp/JavaTest.cs

using UnityEngine;

public static class JavaTest
{
    private const string JavaTestName = "cn.katagames.test.AndroidTestClass";
    private static AndroidJavaObject activity;
    private static AndroidJavaObject Activity
    {
        get
        {
            if (activity == null)
            {
                var UnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
                activity = UnityPlayer.GetStatic("currentActivity");
            }
            return activity;
        }
    }
    private static AndroidJavaClass javaTestClass;
    private static AndroidJavaClass JavaTestClass
    {
        get
        {
            if (javaTestClass==null)
            {
                javaTestClass = new AndroidJavaClass(JavaTestName);
            }
            return javaTestClass;
        }
    }
    public static string GetConfig()
    {
        return JavaTestClass.CallStatic("GetConfig", Activity,"config.txt");
    }
}

2.6 TestUI.cs

 Assets/Scripts/TestUI.cs

using UnityEngine;
using UnityEngine.UI;

public class TestUI : MonoBehaviour
{
    public Text ConfigText;
    private void Awake()
    {
        ConfigText.text = JavaTest.GetConfig();
    }
}

三.测试结果
