Hi,

http://java.sun.com/docs/books/jni/download/jni.pdf 10.9 Violating
Access Control Rules.  In jni.pdf it says "It is possible to write
native code to access or modify fields of an object even though doing
so at the Java programming language level would lead to an
IllegalAccessException."  Does this mean that some aspects of Androids
internals can be 'messed with'? or are things like public/private/
protected not used for enforcing security in the framework? And are
the Manifest.permissions checks done in such a way that this is not a
problem?

Thanks

Chris
