This is just a small mini size hexadecimal/decimals editor that can help you out in learning hexadecimals/decimals or modifying files in hexadecimals/decimals. This is a really small app and it isnt fancy but can do the job very well.
This app can just handle small files of just 4Kb or less, thatz why its not a really big job do'er.
I have learnt so much while writing this app, so i think its a big try(must try infact) if at all you are interested in digits/files modification.And this app is an aid in learning while away from your computer/hackery.
Use this app https://forum.hovatek.com/thread-738.html to learn hexadecimals/decimal/binary/octal. it current version(2.0) is more like a complementary to this app(its not most, they work independently, i just recomends it because it can help so much).
changes:- more support for signed(negative) hexadecimals
requires android:-2.3 or higher
