Android - proprietary ASN.1 encoder

The purpose of the ASN.1 coding specification described here is to have a way to create ASN.1 data sequence in a program without having an ASN.1 compiler capable to read a formal ASN.1 notation.
There are a lot of libraries out there with many different ways to handle the coding/decoding of an ASN.1 message. I needed something simple, cheap and fast so I created this system.
I originally created this years ago in C and now ported in Java for Android.

ASN.1 - what is it ?

ASN.1 stands for Abstract Syntax Notation One, a standard protocol from ITU, is heavily used in telecommunication, for example in ISDN.

There is a lot of literature about ASN.1, books, white papers, online tools, etc. so I'm not duplicating here what already exists "out there" but I just sum up few things I think are interesting.
