That's not something special. That's actually what the algorithms are specified to require, and the APIs reflect that. They're not even Android-specific APIs, they're Java APIs, and the algorithms are standards and not tied to language or platform.
Ideally, you'd pad with random bytes, instead of null bytes, which probably weaken the encryption significantly -- any time an attacker knows part of the message, it makes his job simpler. So I'd say PHP's behavior is a special case, and even a design flaw (both a convenience AND a design flaw, viewed from the standpoint of conflicting requirements). On Jul 19, 5:45 am, "Raymond C.
