libgdx 和 libgdx-sql lite 有问题
Trouble with libgdx and libgdx-sql lite
一切正常，当我尝试调试我的游戏时出现错误：
程序类型已存在：com.badlogic.gdx.sql.Database
Message{kind=ERROR, text=程序类型已经存在：com.badlogic.gdx.sql.Database, sources=[Unknown source file], tool name=Optional.of(D8)}
我正在使用 libgdx 和 gdx-sqlite（在 android studio 中），我从这里下载并按照说明操作：
https://github.com/mrafayaleem/gdx-sqlite
我的代码没有任何问题，因为几天前一切正常。我搜索了很多，但找不到任何解决方案。我认为 gradle 之类的有问题。
这里是Logcat:

一切正常，当我尝试调试我的游戏时出现错误：
程序类型已存在：com.badlogic.gdx.sql.Database Message{kind=ERROR, text=程序类型已经存在：com.badlogic.gdx.sql.Database, sources=[Unknown source file], tool name=Optional.of(D8)}
我正在使用 libgdx 和 gdx-sqlite（在 android studio 中），我从这里下载并按照说明操作：
https://github.com/mrafayaleem/gdx-sqlite
我的代码没有任何问题，因为几天前一切正常。我搜索了很多，但找不到任何解决方案。我认为 gradle 之类的有问题。
这里是Logcat:
