Whether written in C or Java, an app can always fire any Intent it
wants to. But no other process has to listen, or act on it.

Intent receivers can — should! — ask questions such as "Do I know or
care about the sender of this Intent?", "Did the sender have a given
Permission?", "Is the Intent well-formed according to my input
validation rules?", and so on. That's where the security comes from.
There is no magic.
