Subject: [PATCH] Android: Fix NPE when proxy interface method has no arguments

JDK contract: InvocationHandler.invoke's args parameter is null when
the proxied interface method takes no arguments. The proxy handlers
in AndroidRuntimePlugin used `*args` directly, which spread-deref'd
null and threw NullPointerException.
