Hello everyone, i need some help converting a library done by someone else in Java to Basic4Android, this library allows us to use the audio jack on android phones as a serial port, the project explanation can be found here.
I honestly don't know anything about Java, I do have Eclipse installed in my machine but don't know how to use this library and convert it to b4A library, can anyone maybe take a look at it and maybe help me figure out how to get started.
the jar file is this:View attachment
I have already created a library for an ads company called tapit using the tutorials found here in the forums, but for some reason i can not figure out how to work with this file.
any thoughts and suggestions will be appreciated.
