Android Java - Implement Audio Overwrite - $75 Dollars

Hi. So. I have been developing an App for months now. Started programming that very same day. . Now, I have gotten to a point where I need someone to implement overwritting audio recorded with the Library Audio Record. . The Android Studio Project of the App is attached to the Files of this Project. You can see it and test it by yourself. Much of the code and of the classes was extracted, so, do not touch any other thing than Start, Stop, Pause, and Play. . When you press Start, will record. When you press Stop, will stop recording. When you press Play, it will Play what you played, if any. And when you press Pause, it will Pause the Playing. . I have some test version of the Overwriting Implementation, but it crashed, and also it recorded, many times, more than 1 second of white noise (could be extracted saying "when the first non zero sample appears, then start adding samples to the old audio). . Now, another thing I need about this Implementation, it is that if it starts overwritting, to delete all the old audio from that point on, so that if for example, we are overwritting 5 seconds from the Twentieth Second on, that when stopped overwritting at the 25th Second, that it will not continue at the 26th Second with the Old Audio. . So. That is all. Sorry for the unoptimal description. . If you are interested in this Project, send me a message. Thank you for your time. .
