我试图让它在我的galaxy s2 android版本2.3上运行

原因如下：

有没有人知道原因以及如何解决它（我发现以下但是并不太明白，如果它与我有任何关系，因为我根本不使用Gson https://github.com/realm/realm-java/issues/620）

更新：我在libs目录中有本机库

更新 我认为本机.so文件目录的位置在libs目录下是直接的，我认为解决了早期的问题，但提出了以下错误代码：

由于某种原因，Realm无法找到本机库。您使用的是Android Studio还是Eclipse。如果您使用的是Eclipse，请注意需要一些额外的设置，如下所述：http://realm.io/docs/java/0.79.0/#getting-started
