2. NullPointerException (@PlayList:getDatabaseAlbum:386) {Thread-108}
Careful about assigning too much weight to the specific line number.
I see no other possibility besides 'queryBuilder'(var db) be returning null. Any idea why the error ?
I think it is more likely that your DAO is null. There is no way for the dao.queryBuild(...) method to return null:
public QueryBuilder<T, ID> queryBuilder() {
checkForInitialized();
return new QueryBuilder<T, ID>(databaseType, tableInfo, this);
}

public void checkAll(final Group group, final Album album, final List<Music> musics, final OnCheckListener callback){ new Thread(new Runnable() { @Override public void run() { Handler handler = new Handler(Looper.getMainLooper()); final Map<Integer,Boolean> map = new HashMap<Integer, Boolean>(); Album _album = getDatabaseAlbum(group, album); if (!_album.hasValidId()) { for (int index=0; index < musics.size(); index++) map.put(index, false); handler.post(new Runnable() { @Override public void run() { callback.onCheckResult(map); } }); return; } for (int index=0; index < musics.size(); index++){ map.put(index, hasValidId(getDatabaseMusic(_album, musics.get(index)))); } handler.post(new Runnable() { @Override public void run() { callback.onCheckResult(map); } }); } }).start(); }
Location of the error:
383 private Album getDatabaseAlbum(Group group, Album album){
384 QueryBuilder<Album, Integer> db = mAlbumDao.queryBuilder();
385 try {
386 Where<Album,Integer> where = db.where()
387 .eq(Album.GROUP_ID_FIELD, group.getId()).and()
.eq(Album.ARTIST_FIELD, new SelectArg(album.getArtist())).and()
.eq(Album.URL_FIELD, new SelectArg(album.getUrl()));
Album _album = where.queryForFirst();if (hasValidId(_album)) album = _album; else album.invalidateId(); } catch (SQLException e) { Log.d(MainActivity.TAG, "Music", e); album.invalidateId(); } return album; }
I see no other possibility besides 'queryBuilder'(var db) be returning null. Any idea why the error ?
384 QueryBuilder<Album, Integer> db = mAlbumDao.queryBuilder();
385 try {

To avoid boot daos null pointer, I capture the error:
public void initialize() {
databaseHelper = getHelper();
try {
mGroupDao = databaseHelper.getDao(Group.class);
mAlbumDao = databaseHelper.getDao(Album.class);
mMusicDao = databaseHelper.getDao(Music.class);
} catch (SQLException e){
throw new AssertionError(e.getMessage());
}
getDefaultGroup(); // initializes the default group.
}
Since you mentioned that the line number may be wrong, I will give attention to other things, as:
.eq(Album.GROUP_ID_FIELD, group.getId()).and()
Maybe "group" is the cause of the null pointer.

I'm going to close this issue. Feel free to disagree and reopen if you have some more information that this is a bug in ORMLite. Thanks.
