java – Unsafe class in Android?

Posted by: admin June 15, 2020 Leave a comment

Questions:

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.

How to&Answers:

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

Answer:

It has the JNI bridge which could allow for just about anything but it’s not “unsafe” since you have to code that into your app. As far as I know there is no exposed way to get out of the JVM sandbox (at least not without finding an exploit).
