o Add Android.mk file. o Add @hide so it is not exposed in the public API. It is not yet in shape. o Prefer @throws to @exception o Do not use @version. This is meaningless in Android. o Prefer classes 'final' unless explicitly allowing inheritance (See "Effective Java" item 15) o Prefer CamelCaps java naming even for acronyms (OBEXHelper -> ObexHelper) o Use the built-in MD5 library. o Move ObexConstants into ObexHelper. o Remove unused variables. o Prefer stricter access priveleges. Most importantly, avoid public fields. o Don't use 'import java.io.*'. Name each class explicitly. o Delete commented out code. If its not used then remove it.
