Android media store tutorial | List all sdcard audio |List all sdcard video | List all sdcard images

Hello Friends,
       Today, I am going to share my another post on Android Media Store. In this post
I am going to show you how to query media file like audio,images and video using
Android Media Store and Android Content Resolver .









For Listing all Images:
private void parseAllImages() {
        try {
            String[] projection = {MediaStore.Images.Media.DATA};
            cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    projection, // Which columns to return
                    null,       // Return all rows
                    null,
                    null);

          
            int size = cursor.getCount();

            /*******  If size is 0, there are no images on the SD Card. *****/

            if (size == 0) {

            } else {

                int thumbID = 0;
                while (cursor.moveToNext()) {

                    int file_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

                    /**************** Captured image details ************/

                    /*****  Used to show image on view in LoadImagesFromSDCard class ******/
                    String path = cursor.getString(file_ColumnIndex);

                    String fileName = path.substring(path.lastIndexOf("/") + 1, path.length());

                    MediaFileInfo mediaFileInfo = new MediaFileInfo();
                    mediaFileInfo.setFilePath(path);
                    mediaFileInfo.setFileName(fileName);
                    mediaFileInfo.setFileType(type);
                    mediaList.add(mediaFileInfo);
                }
            }


        } catch (Exception e) {
            e.printStackTrace();
        }
} 


For Listing all Video(.mp4)


private void parseAllVideo() {
        try {
            String name = null;
            String[] thumbColumns = {MediaStore.Video.Thumbnails.DATA,
                    MediaStore.Video.Thumbnails.VIDEO_ID};

            int video_column_index;
            String[] proj = {MediaStore.Video.Media._ID,
                    MediaStore.Video.Media.DATA,
                    MediaStore.Video.Media.DISPLAY_NAME,
                    MediaStore.Video.Media.SIZE};
            Cursor videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
                    proj, null, null, null);
            int count = videocursor.getCount();
            Log.d("No of video", "" + count);
            for (int i = 0; i < count; i++) {
                MediaFileInfo mediaFileInfo = new MediaFileInfo();
                video_column_index = videocursor
                        .getColumnIndexOrThrow(MediaStore.Video.Media.DISPLAY_NAME);
                videocursor.moveToPosition(i);
                name = videocursor.getString(video_column_index);

                mediaFileInfo.setFileName(name);

                int column_index = videocursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                videocursor.moveToPosition(i);
                String filepath = videocursor.getString(column_index);

                mediaFileInfo.setFilePath(filepath);
                mediaFileInfo.setFileType(type);
                mediaList.add(mediaFileInfo);
                // id += " Size(KB):" +
                // videocursor.getString(video_column_index);


            }
            videocursor.close();

        } catch (Exception e) {
            e.printStackTrace();
        }
} 



For Listing All Audio


private void parseAllAudio() {
        try {
            String TAG = "Audio";
            Cursor cur = getContentResolver().query(
                    MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, null, null,
                    null);

            if (cur == null) {
                // Query failed...
                Log.e(TAG, "Failed to retrieve music: cursor is null :-(");

            }
            else if (!cur.moveToFirst()) {
                // Nothing to query. There is no music on the device. How boring.
                Log.e(TAG, "Failed to move cursor to first row (no query results).");

            }else {
                Log.i(TAG, "Listing...");
                // retrieve the indices of the columns where the ID, title, etc. of the song are

                // add each song to mItems
                do {
                    int artistColumn = cur.getColumnIndex(MediaStore.Audio.Media.ARTIST);
                    int titleColumn = cur.getColumnIndex(MediaStore.Audio.Media.TITLE);
                    int albumColumn = cur.getColumnIndex(MediaStore.Audio.Media.ALBUM);
                    int durationColumn = cur.getColumnIndex(MediaStore.Audio.Media.DURATION);
                    int idColumn = cur.getColumnIndex(MediaStore.Audio.Media._ID);
                    int filePathIndex = cur.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                    Log.i(TAG, "Title column index: " + String.valueOf(titleColumn));
                    Log.i(TAG, "ID column index: " + String.valueOf(titleColumn));

                    Log.i("Final ", "ID: " + cur.getString(idColumn) + " Title: " + cur.getString(titleColumn) + "Path: " + cur.getString(filePathIndex));
                    MediaFileInfo audio = new MediaFileInfo();
                    audio.setFileName(cur.getString(titleColumn));
                    audio.setFilePath(cur.getString(filePathIndex));
                    audio.setFileType(type);
                    mediaList.add(audio);

                } while (cur.moveToNext());
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
}

  1. Hi Mukesh,

    This code is not running in Android 4.4 version. In this version the app is not finding the actual path of the video in the sd card. Can you please help me to find out the problem.

    Thanks in advance.
