Android Question int to Byte for use with async streams

Two reminders for you:
- a byte has a range -127 to +128
- an int counts for 4 bytes
So, for your application, if you need to send out only significant bytes than you have to convert "keycode" to its lowest-byte counterpart (i.e. masking out the three highest valued bytes) and insert that into the stream. Otherwise just take in account on the receiving part that "keycode" counts for 4 bytes and not a single one.

ps: somewhere in my mind there's a fading recall about an automatic conversion between integer and byte, but I can't clearly focus it right now

If you use 4 bytes, It's easy! But on the other side you have much work to do to produce a full int!

I don't think that there is any keycode larger than 255. You can send it like this:

B4X:

AStream.Write(Array As Byte(Keycode))

Thanks Erel and eveyone that replied, that worked fine for what I needed, I can't believe I didn't try that, I spent ages messing about thinking I need to do some conversion on the int.
