Android IPC servers can't defer "listening" while some slow or async initialization process completes. Instead, Android *tells* a server to initialize itself just-in-time for the first client connection. And this instruction arrives as a callback to Service#onCreate() then Service#onBind() on the app's main thread, where blocking to load a security policy would risk an "Application Not Responding" (ANR) error.

@groakley I can't seem to assign this to you but as creator of the existing composite security policies could you please review? |
