notes for android bluetooth source code

from this one, I use English to write my blog

I've read android source code for half a month, here is some notes and thinking

abbreviations

related to bt profile

first I need to read the fucking bluetooth profiles

A2DPAdvanced Audio Distribution Profile

not related to bt profile

second I need to read the fucking source code directory to overview bluetooth module

some thinking

api:api is used by other module
act:receive from other module, usually use call back
jni native:just encapsulation to if

reflection

I've read nfc code for a month but find no vulnerable, the main reason is
that I just read it, but think nothing.
why I cannt think, because too many abbreviation I dont know, I just lost my
self in the codes.
when read a module of android, we must take question to read.

example:

• how to trigger the vulnerability
• android how to init nfc/bt stack control block
• data flow in handset
