的字段’license’是必需的
我在Android Studio中创建新项目时尝试使用Gemini API Starter模板的代码。
默认模板使用的是很久之前就已废弃的“gemini-pro”模型（他们没有更新模板），所以我将其改成了gemini-1.5-flash。
但我一直遇到解析错误：

我看到一个类似的提问，API没有返回所需的字段，但据说已经修复了（是另一个字段）：Gemini Api Android: SerializationException when deserializing response from server
提前感谢
回答：
我将generativeai依赖从0.2.2升级到了0.9.0，现在它可以工作了。你可以试试这个 👍
