Damn, it's not me talking about "our framework", you are mentioning
when it fits your needs.

If you do not have a clearly defined user space framework, then we
talk about a completely random conglomeration of applications which
need to be brought into submission by some global brute force
approach.

I'm tired of this, really. You just use terminlology as it fits to
defend the complete design failure of android. But you fail to trick
me :)

Can you please explain in a consistent way how the application stack
and the underlying framework (which exists according to android docs)
is handling events and how the separation of trust level works ?

We need to know that, otherwise we turn in circles forever.

Thanks,
