Android MediaStore - SQLiteException: Keine solche Spalte: Titel

Question

Ich versuche, eine Liste von Songs zu einem Recyclerview zu füllen. Ich habe alle anderen Tabs sortiert, aber bei allen Songs weigert es sich zu arbeiten. Ich verwende MediaStore.Audio.Media.TITLE.

Das ist mein Stack-Trace:

Meine Cursor-Methode ist wie so:

Cursor cursor = context.getContentResolver().query(
    MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, 
    new String[]{ 
      //MediaStore.Audio.Media._ID, 
      MediaStore.Audio.Albums._ID, 
      MediaStore.Audio.Media.TITLE, 
      MediaStore.Audio.Artists.ARTIST, 
      MediaStore.Audio.Albums.ALBUM 
      //MediaStore.Audio.Media.DURATION 
    }, 
    null, 
    null, 
    MediaStore.Audio.Media.TITLE + " ASC" 
); 
if (cursor != null) { 
    //count = cursor.getCount(); 
    cursor.moveToFirst(); 
    do { 
     artArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Albums._ID))); 
     songsArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Media.TITLE))); 
     artistsArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Artists.ARTIST))); 
     albumsArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM))); 
    } while (cursor.moveToNext()); 
    cursor.close(); 
} 

Also, was ist die richtige Zeichenfolge zu holen? Alle anderen Themen schlagen vor, MediaStore.Audio.Media.TITLE zu verwenden, aber das scheint zu fehlen. Ist das etwas, das in der neuesten SDK entfernt wurde?

Answer 1

Ich fand es heraus. Ich war MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI in dem Cursor abruft, wenn ich MediaStore.Audio.Media.EXTERNAL_CONTENT_URI

Hier ist der Arbeitscode für die Zukunft holen werden soll:

Cursor cursor = context.getContentResolver().query(
     MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, 
     new String[]{ 
       MediaStore.Audio.Media._ID, 
       //MediaStore.Audio.Albums._ID, 
       MediaStore.Audio.Media.TITLE, 
       MediaStore.Audio.Media.ARTIST, 
       MediaStore.Audio.Media.ALBUM 
       //MediaStore.Audio.Media.DURATION 
     }, 
     null, 
     null, 
     MediaStore.Audio.Media.TITLE + " ASC" 
); 
if (cursor != null) { 
    //count = cursor.getCount(); 
    cursor.moveToFirst(); 
    do { 
     artArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Albums._ID))); 
     songsArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Media.TITLE))); 
     artistsArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Artists.ARTIST))); 
     albumsArrayList.add(cursor.getString(
       cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM))); 
    } while (cursor.moveToNext()); 
    cursor.close();
