I am searching the answer from google and android website.
Because the iPhone can do that. But I can't find the Android has the API to do.
Because the microphone pin and GND pin maybe change in the different android phone.
So, I try to use the line-in (right) to get the data.
I checked the Hijack project, it used the microphone pin to get data, and used iPhone.
Does android phone can do the same function?
Thank you for your answer.
