Unable to get all Video files from storage Android

Am using following method to get video files from storage. it retrieves only directories files but not read files inside sub-directory files.

Example:- i can read file from WhatsApp Video but in the same folder there is a sub folder name sent i can't read the files inside.

any help, how can i read all folder and sub-folder

public class GetVideos {
@RequiresApi(api = Build.VERSION_CODES.Q)
public void getAllVideosData(Context context, ArrayList<VideoViewInfo> AllVideosData) {
String[] projection = new String[] {
MediaStore.Video.Media._ID,
MediaStore.Video.Media.TITLE,
MediaStore.Video.VideoColumns.DATA,
MediaStore.Video.Media.BUCKET_DISPLAY_NAME,
MediaStore.Video.Media.DATE_TAKEN,
MediaStore.Video.Media.DURATION,
MediaStore.Video.Media.RESOLUTION,
MediaStore.Video.Media.SIZE
};
Uri Video = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String orderBy = MediaStore.Video.Media.DATE_TAKEN;
@SuppressLint("Recycle")
Cursor cur = context.getContentResolver().query(Video, projection,null,null,orderBy );
assert cur != null;
Log.i("ListingVideo"," query count=" + cur.getCount());
if (cur.moveToNext()) {
String id;
String title;
String filePath;
String bucketName;
String date;
String duration;
String resolution;
String size;
int tempId = cur.getColumnIndex(MediaStore.Video.Media._ID);
int titleTemp = cur.getColumnIndex(MediaStore.Video.Media.TITLE);
int filePathTemp = cur.getColumnIndex(MediaStore.Video.Media.DATA);
int bucketTemp = cur.getColumnIndex(MediaStore.Video.Media.BUCKET_DISPLAY_NAME);
int dateTemp = cur.getColumnIndex(MediaStore.Video.Media.DATE_TAKEN);
int durationTemp = cur.getColumnIndex(MediaStore.Video.Media.DURATION);
int resolutionTemp = cur.getColumnIndex(MediaStore.Video.Media.RESOLUTION);
int sizeTemp = cur.getColumnIndex(MediaStore.Video.Media.SIZE);
do {
id = cur.getString(tempId);
title = cur.getString(titleTemp);
filePath = cur.getString(filePathTemp);
bucketName = cur.getString(bucketTemp);
date = cur.getString(dateTemp);
duration = cur.getString(durationTemp);
resolution = cur.getString(resolutionTemp);
size = cur.getString(sizeTemp);
Log.d(TAG, "getAllVideosData: "+bucketName);
VideoViewInfo vvi = new VideoViewInfo(id, title, filePath, bucketName, date, duration, resolution, size);
AllVideosData.add(vvi);
} while (cur.moveToNext());
}
}
}

What should i do to get all video file in my storage ?

You can run a recursive function to list all video files like

void findVideos(File dir, ArrayList<String> list){
    for (File file : dir.listFiles()) {
        if (file.isDirectory()) findVideos(file, list);
        else if(file.getAbsolutePath().contains(".mp4")) list.add(file.getAbsolutePath());
    }
}

Or you can query the mediastore like done in this repository here

It's really hard and full of a mess when doing file handling
because you only access the files but what about the subdirectories in it? well in the case of

@Kursh's answer recursion will not help either

because it will just go deep into the sub directories never to come back I had developed the algorithm but it was not really inefficient, but you can use this library and remember to use it in an ASYNC TAK or Coroutine
