做了Android的Dalvik标准库有类似于Java SE的无证类sun.misc.Unsafe任何类，允许直接访问内存。

Do the Android Dalvik standard libraries have any class similar to the undocumented class sun.misc.Unsafe in Java SE which allows direct access to memory.

推荐答案

Android的实现sun.misc.Unsafe的部分地区，主要是为了支持JSR-166并发类。这不是Android的API的一部分。

Android implements parts of sun.misc.Unsafe, primarily to support the JSR-166 concurrency classes. It's not part of the Android API.
