How to get songs and other media from an album?

I want to get songs and other MEDIA data from Id album. All I have is Album Id, and I tried many solutions, but none of them succeeded.

My code snippet:

ContentResolver contentResolver = getContentResolver();
        Uri mediaUri = ContentUris.withAppendedId(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, albumId);
        Log.wtf("SKJDBKJ", mediaUri.toString());
        Cursor mediaCursor = contentResolver.query(mediaUri, null, null, null, null);

        // if the cursor is null.
        if(mediaCursor != null && mediaCursor.moveToFirst())
        {
            Log.wtf("DSJK", "entered cursor");
            //get Columns
            int titleColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM);
            int idColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media._ID);
            int artistColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);

            // Store the title, id and artist name in Song Array list.
            do
            {
                long thisId = mediaCursor.getLong(idColumn);
                String thisTitle = mediaCursor.getString(titleColumn);
                String thisArtist = mediaCursor.getString(artistColumn);
                Log.wtf("Title", thisTitle);

                // Add the info to our array.
                songArrayList.add(new Song(thisId, thisTitle, thisArtist));
            }
            while (mediaCursor.moveToNext());

            // For best practices, close the cursor after use.
            mediaCursor.close();
        }

Magazine for the mediaUrireturn path of the current album, for example .: content://media/external/audio/media/41. Will someone tell me how to do this?

I realized this after a lot of trial and error. I don’t know how much the best and safest way to do this is, but how much it works, I’m happy.

I changed my code a bit and compared album IDs. Here is a snippet:

ContentResolver contentResolver = getContentResolver();
        Uri mediaUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
        Log.wtf("SKJDBKJ", mediaUri.toString());
        Cursor mediaCursor = contentResolver.query(mediaUri, null, null, null, null);

        // if the cursor is null.
        if(mediaCursor != null && mediaCursor.moveToFirst())
        {
            Log.wtf("DSJK", "entered cursor");
            //get Columns
            int titleColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
            int idColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media._ID);
            int artistColumn = mediaCursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
            int albumId = mediaCursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID);

            // Store the title, id and artist name in Song Array list.
            do
            {
                long thisId = mediaCursor.getLong(idColumn);
                long thisalbumId = mediaCursor.getLong(albumId);
                String thisTitle = mediaCursor.getString(titleColumn);
                String thisArtist = mediaCursor.getString(artistColumn);

                // Add the info to our array.
                if(this.albumId == thisalbumId)
                {
                    Log.wtf("SAME2SAME", String.valueOf(thisalbumId));
                    Log.wtf("SAME2SAME", String.valueOf(this.albumId));
                    songArrayList.add(new Song(thisId, thisTitle, thisArtist));
                }
            }
            while (mediaCursor.moveToNext());

            // For best practices, close the cursor after use.
            mediaCursor.close();
        }

I changed:

  • Received album Id Media.
  • album Id bundle extras.

when you put the cursor.movenext function in a while loop, the first row of the MediaStore database will be passed without saving the data, as the function moves the cursor and then checks that it is better to make a value instead of putting the movenext function at that time.

  try {
            Projection = new String[]{
            MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.ALBUM
            , MediaStore.Audio.Media.ARTIST,MediaStore.Audio.Media.DATA,                                    MediaStore.Audio.Media.SIZE};

            Cursor cursor = getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, Projection, null, null, null);

            cursor.moveToFirst();

            for (int i = 0; i < 5; i++) {
                columns[i] = cursor.getColumnIndex(Projection[i]);
            }

            Music tempMusic = new Music();

            while (next) {
                tempMusic.setName(cursor.getString(columns[0]));
                tempMusic.setAlbum(cursor.getString(columns[1]));
                tempMusic.setArtist(cursor.getString(columns[2]));
                tempMusic.setUri(cursor.getString(columns[3]));
                tempMusic.setSize(cursor.getDouble(columns[4]));
                if(!cursor.moveToNext())
                {
                    next=false;
                }
                musicss.add(tempMusic);

                tempMusic = new Music();
            }
