ffmpeg - 我无法在我的应用程序中获取剪切的音乐文件

Question

我已经可以使用 FFmpeg 剪切音乐文件并保存在外部存储中。但我无法在我的应用程序中剪切音乐文件来播放音乐文件。
我已经使用此代码剪切音乐文件

private void trimMusic(long position_start, long position_end, String SONG_NAME) {
    File folder = new File(Environment.getExternalStorageDirectory() + "/MusicEditor/");
    folder.setReadable(true);
    if (!folder.exists()) {
        folder.mkdir();
    }
    String filePrefix = SONG_NAME;

    String fileExt = ".mp3";
    System.out.println("audio"+fileExt);
    dest = new File(folder, filePrefix + fileExt);
    original_path = path;

    duration = (endMs - startMs) / 1000;
    filePath = dest.getAbsolutePath();

    Log.d("chandoixuanduc",filePath);

    command = new String[]{"-ss", "" + startMs / 1000, "-y", "-i", original_path, "-t", "" + (endMs - startMs) / 1000, "-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath};
    execffmpegBinary(command);
}

private void execffmpegBinary(final String[] command) {
    Config.enableLogCallback(new LogCallback() {
        @Override
        public void apply(LogMessage message) {
            Log.e(Config.TAG, message.getText());
        }
    });

    Config.enableLogCallback(new LogCallback() {
        @Override
        public void apply(LogMessage message) {
            Log.e(Config.TAG, message.getText());
        }
    });

    Config.enableStatisticsCallback(new StatisticsCallback() {
        @Override
        public void apply(Statistics newStatistics) {

        }
    });
    Log.d(TAG, "Started command : ffmpeg " + Arrays.toString(command));


    long executionId = FFmpeg.executeAsync(command, new ExecuteCallback() {
        @Override
        public void apply(long executionId, int returnCode) {
            if (returnCode == RETURN_CODE_SUCCESS) {
                //  progressDialog.dismiss();
                dialog.dismiss();
                Toast.makeText(getActivity(), R.string.status_cut_music_sus, Toast.LENGTH_LONG).show();
                Log.d("chandoixuanduc","RETURN_CODE_SUCCESS");

            }
            else if (returnCode == RETURN_CODE_CANCEL) {
                Log.d("chandoixuanduc","RETURN_CODE_CANCEL");
            }
            else {
                Toast.makeText(getActivity(), R.string.status_cut_music_failed, Toast.LENGTH_LONG).show();
                Log.d("chandoixuanduc","RETURN_CODE_FAILED");
            }
        }
    });
}

尽管我检查了它，但我的手机中有一个剪切的音乐文件，但是当我获取所有文件 mp3 进行测试时，我无法在我的应用程序中获得剪切的音乐文件。

public List<AudioModel> getAllAudioFromDevice(final Context context) {
        final List<AudioModel> tempAudioList = new ArrayList<>();
        try {
            Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
            String[] projection = {MediaStore.Audio.AudioColumns.DATA, MediaStore.Audio.AudioColumns.ALBUM, MediaStore.Audio.ArtistColumns.ARTIST,};
            cursor = context.getContentResolver().query(uri,
                    projection,
                    null,
                    null,
                    null);

            if (cursor != null) {
                cursor.moveToFirst();
                while (!cursor.isAfterLast()) {
                    AudioModel audioModel = new AudioModel();
                    String path = cursor.getString(0);
                    String album = cursor.getString(1);
                    String artist = cursor.getString(2);
                    String name = path.substring(path.lastIndexOf("/") + 1);
                    Uri urisong=Uri.parse(cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA)));
                    MediaPlayer mp = MediaPlayer.create(getActivity(), urisong);
                    long duration=mp.getDuration();
                    audioModel.setaName(name);
                    audioModel.setaAlbum(album);
                    audioModel.setaArtist(artist);
                    audioModel.setaPath(path);
                    audioModel.setDuration(duration);
                    audioModel.setUri(urisong);
                    Log.d("kskskskkd",audioModel.duration+"  "+audioModel.uri);
                    tempAudioList.add(audioModel);
                    cursor.moveToNext();
                }
                cursor.close();
            }
        }catch (Exception e){

        }
        return tempAudioList;
    }

如何在我的应用程序中获得剪切的文件音乐？？？

检查是否保存在沙盒路径中，因为权限问题查询无法获取到沙盒路径中的文件，可以自行遍历软件的沙盒目录
