No, you are right.

But this explaination given by K & R (Brian Kernighan and Dennis Ritchie) might help you to understand more, why and were we should use it.

K&R states that there are two reasons for using a typedef.
  First, it provides a means to make a program more portable. Instead of having to change a type 
  everywhere it appears throughout the program's source files, only a single typedef statement needs
  to be changed.

  Second, a typedef can make a complex declaration easier to understand.

Is there a case where '&' yields a lower performance than '%'? Does compiler optimize it automatically?

The following two code sequences produce the same result:

uint mod = val % 4;   
uint mod1 = val & 0x3;

I can use both to calculate the same result. I know that in hardware the & operator is much more simpler realised than the % operator. Therefore I expect it to have a better performance than the % operator.

Other than uid/gid is there any permission verification in runtime for an android app?

In android generally when an app is installed, the PackageInstallerActivity and PackageManagerService make sure to assign the supplementary gid's to the app. This determines the level of access when an app is invoked everytime.

I just wanted to confirm if any verification process takes place in the runtime from packagemanager or any other service for that matter.

The app is granted the corresponding access from the gid's that should get it running technically and Packagemanager will only come into picture incase of updating the app.

Is my understanding correct?
