How to capture ring back tone (RBT) sound and record it in java android? <p>I hope to find answer here, I want to get the calling parties ring tone, I mean when you call somebody, before your call is established with that person, you may here some music instead of default beep sound, actually that person may have activated RBT or RING BACK TONE (from aT&amp;T maybe) on her mobile number. How I can capture her ring back tone sound stream and convert it to array of byte[]? I need to capture that RBT? thanks all,</p>
