Unity工程插件化加载方案

1. 宿主工程依赖 VirtualApk implementation com.didi.virtualapk:core:0.9.8.0.1
2. 在Application中初始化VirtualApk

@Override
    protected void attachBaseContext(Context base) {
          
   
        super.attachBaseContext(base);
        PluginManager.getInstance(base).init();
    }

在启动插件前加载插件apk

com.didi.virtualapk.PluginManager.getInstance(context).loadPlugin(apkFile);

启动插件的activity

public static void runPlugin(Context context, Intent intent) {
          
   
        if (com.didi.virtualapk.PluginManager.getInstance(context).getLoadedPlugin(PLUGIN_PACKAGE_NAME) == null) {
          
   
            return;
        }
        if (intent == null) {
          
   
            intent = new Intent();
        }
        //PLUGIN_PACKAGE_NAME 插件APK的包名
        //PLUGIN_ATY_NAME 要启动的插件APK中的activity的全路径， ex:com.demo.activity.PluginActivity
        intent.setComponent(new ComponentName(PLUGIN_PACKAGE_NAME, PLUGIN_ATY_NAME));
        context.startActivity(intent);
    }

3. Unity导出Android 工程文件，在目标activity中添加以下修改

@Override protected void onCreate(Bundle savedInstanceState)
    {
          
   
    	//在实例化mUnityPlayer 前修改so文件加载路径
        getApplicationInfo().nativeLibraryDir = "/data/data/com.****.****/app_valibs";
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        super.onCreate(savedInstanceState);
        mUnityPlayer = new UnityPlayer(this);
        setContentView(mUnityPlayer);
        mUnityPlayer.requestFocus();
    }

@Override
    public String getPackageCodePath() {
          
   
        File file = new File("/sdcard/unitytest/test.apk");    
        return file.getAbsolutePath();
    }

//指定插件工程的的资源索引
    aaptOptions {
          
   
        //additionalParameters --allow-reserved-package-id,--package-id,0x70
        //避免加载插件时，资源id的索引重合
        additionalParameters --allow-reserved-package-id,--package-id,0x80
        noCompress .unity3d, .ress, .resource, .obb,config.json
    }

4. 遇到的问题：经过插件话加载的unity工程在执行mUnityPlayer.quit()会崩溃，且没有日常日志，无法定位。

@Override protected void onDestroy ()
    {
          
   
        mUnityPlayer.quit();
