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();
        }
}
