java - Android 媒体记录器停止异常

Question

我正在从 android 媒体记录器录制视频和音频...
我正在检查剪辑长度，如果少于 2 秒，请将其删除...
但问题是，如果我从文件路径检查文件的持续时间，MediaRecorder 每次抛出异常后都会抛出异常，即使我录制了 10 秒的音频？
但是当我评论代码以检查创建的视频的持续时间时，它工作正常......
以下是我的代码

if (prMediaRecorder != null) {
    try {
        prMediaRecorder.stop();
        timer.cancel();
        PathNameArray.add(prRecordedFile.getPath());
        Log.e("No Exception", "File Added and Saved");

        ////////////// Check Length and Delete File
        if (prRecordedFile != null) {
            if (MediaPlayer.create(getApplicationContext(), Uri.fromFile(new File(
                            prRecordedFile.getPath()))).getDuration() <= 2000) {

                File file = new File(prRecordedFile.getPath());
                boolean deleted = file.delete();
                Toast.makeText(getApplicationContext(),
                        "Video Clip Length Too Short, Clip Not Added",
                        Toast.LENGTH_SHORT).show();

                PathNameArray.remove(PathNameArray.size() - 1);
            }
        }

    } catch (RuntimeException e) {
        Toast.makeText(getApplicationContext(),
                "Corrupt Clip, Clip Not Added",
                Toast.LENGTH_SHORT).show();
        File file = new File(prRecordedFile.getPath());
        boolean deleted = file.delete();
        timer.cancel();
        Log.e("Exception Caught", "File Not Added");

    } finally {
        try {
            prCamera.reconnect();
        } catch (IOException e) {

            e.printStackTrace();
        }
    }
}

prMediaRecorder = new MediaRecorder();
MarkerName = null;

请帮帮我，我的代码有问题还是什么？

我解决了这个问题，
问题是我从 MediaPlayer
获取持续时间的方式 相反，我使用了这段代码，它被修复了……

//////////////// Check Length and Delete File
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(prRecordedFile.getPath());
String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
long timeInmillisec = Long.parseLong(time);
