Android Media Recorder停止例外

Question

我正在從Android媒體錄制器錄制視頻和音頻......
我正在檢查剪輯長度，如果不到2秒，刪除它...
但問題是，如果我從文件路徑檢查文件的持續時間，MediaRecorder會在拋出異常后每次拋出異常，即使我錄制了10秒的音頻？
但是當我評論代碼來檢查視頻創建的持續時間時，它會變得很糟糕......
以下是我的代碼

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;

請幫幫我，我的代碼有什么問題或什么？

我解決了這個問題，
問題是我從MediaPlayer獲得持續時間的方式
相反，我使用此代碼，它已修復...

//////////////// 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);
