     * Sets the next output file descriptor to be used when the maximum filesize is reached

     * on the prior output {@link #setOutputFile} or {@link #setNextOutputFile}). File descriptor

     * must be seekable and in read-write mode. After setting the next output file, application

     * should not use the file referenced by this file descriptor until {@link #stop}. Application

     * must call this after receiving on the {@link android.media.MediaRecorder.OnInfoListener} a

     * "what" code of {@link #MEDIA_RECORDER_INFO_MAX_FILESIZE_APPROACHING} and before receiving

     * a "what" code of {@link #MEDIA_RECORDER_INFO_MAX_FILESIZE_REACHED}. The file is not used

     * until switching to that output. Application will receive

     * {@link #MEDIA_RECORDER_INFO_NEXT_OUTPUT_FILE_STARTED} when the next output file is used.

     * Application will not be able to set a new output file if the previous one has not been used.

     * Application is responsible for cleaning up unused files after {@link #stop} is called.

     * must be seekable and writable. After setting the next output file, application should not

     * use the file referenced by this file descriptor until {@link #stop}. It is the application's

     * responsibility to close the file descriptor. It is safe to do so as soon as this call returns.
