It's a "depends".  If two activities are running with different uids, they
can have different permissions; if with the same uids, they have the same
permissions.  A particular .apk can only have one uid assigned to it, so all
of the components in it share the same permissions (and this is why the
uses-permission tag is at the top of the manifest).

There are tons of examples in the source tree of using permissions; probably
majority of .apks use one permission or another.

Also be sure you read the basic documentation on security:

http://developer.android.com/guide/topics/security/security.html

And you should understand what an application is:

Note: please don't send private questions to me, as I don't have time to
provide private support.  All such questions should be posted on public
forums, where I and others can see and answer them.
