问题 I am trying to work out an example of recording audio, with the data storage being handled by the app, not MediaRecorder . Use cases include storing the recording on internal storage or encrypting the recording.

问题 I am using fragments inside an activity. I am using MediaRecorder to for audio recording. I have two part of an activity. 1st itself the Activity which will list the recorded file. On it's right side the AudioRecording Activity is called when one select to record for a new file. When the any of the listed file is selected i am using AudioPlayer as to play the recorded file. I am here able to convert the Activity into fragment but when i press on Stop it is terminating the application. Please
