<；已解决>；Android上的Unity3d sqlite可以'；找不到数据库

我正试图在我的Unity3d项目中分发一个预填充的SQLite数据库。它可以在编辑器和IOS上工作，但不能在Android上工作

我已经在谷歌上搜索和测试了大约一周的不同解决方案，但没有成功。在许多其他可能的解决方案中，我一直在考虑以下问题：

但仍然无法让它工作

我创建了一个特定的小项目，用于在Android上进行测试

数据库放置在流媒体资源中

当我在Android上运行应用程序时，会收到以下消息：

/存储/仿真/0/Android/data/com.defaultCompany.SqliteAndroidTestProject/files/testAndroid.db不存在

正在尝试从创建：/data/app/com.DefaultComapany.SqliteAndroidtestProject1/base.apk/assets/testAndroid.db

我相信问题在于Android处理文件等的方式，但我想我无法将DB移动到正确的资产文件夹

以下是我使用的完整代码（我删除了IOS代码）：

我非常感谢您的帮助，因为我的项目因此而暂停。

在阅读时，我仍然指出Android流媒体资产不起作用。应该坚持不懈
