How to append to Android MediaRecorder output file

I am wondering if there开发者_Go百科 is a way to tell the MediaRecorder to append to an existing audio file instead of starting it over from the beginning. In other words, I would like to call setOutputFile() with an existing file and have the new audio appended to that file instead of erasing it.

Android MediaRecorder does not support appending.

Once you are recording the only possible actions are stop and reset.

So one option is saving as a WAV file, and then append to an existing WAV file saved on the SD card using AudioRecord instead. AudioRecord.read() allows one to save the raw audiodata to a buffer, which you could easily append to an existing recording.
