How to get file size of live video recording in an

问题:

How can I get the video file size while recording a video in Android using a MediaRecorder?

回答1:

String recVideoPath = Environment.getExternalStorageDirectory() + videoRecordedFileName;

File file = new File(recVideoPath);
long fileVideo = file.length();

More or less something like the one above.

Put this in a thread, or where ever you are updating the UI

currentPosition = (int) mediaPlayer.getCurrentPosition();
yourProgressBar.setProgress(currentPosition);

I hope this helps :)
