Try this:

B4X:

dim testString as String
testString="test"
Dim buffer() As Byte
buffer=testString.GetBytes("UTF8")
AStream.Write(buffer)

Nice example. If your sending strings to another android device, how would the other side know what to do with it?

I guess I can use prefix before the actual string.

if you want to send label1.text = "something" and show up on the other android device as label1.text= "something"

B4X:

dim label1 asString
label1 = "label1" & label1.text Dim buffer() AsByte
buffer=label1.GetBytes("UTF8")
AStream.Write(buffer)

on the other end when you receive the string check the prefix to know where it goes, then strip the prefix.
