I need to cut an audio file, that is available on sdcard. Cut means I want to take some portion of a audio file to set a ringtone. I can set ringtone, but how I can do cut an audio file from any position?

Answer 1

Basically with pure Android SDK, it is not possible. We have to use Java and if any one does not want to do from scratch, he/she can use the Ringdroid open source project.
