the rest of causes :

this my gradle :

------ property declare like this ------

public class FolderDao extends AbstractDao<Folder, Long> { public static final String TABLENAME = "FOLDER"; private DaoSession daoSession;  public static class Properties {     public static final Property FolderPath = new Property(8, String.class, "folderPath", false, "FOLDER_PATH");     public static final Property FolderSourceId = new Property(5, Long.class, "folderSourceId", false, "FOLDER_SOURCE_ID");     public static final Property Id = new Property(0, Long.class, "id", true, "_id");     public static final Property IsCamera = new Property(3, Boolean.class, "isCamera", false, "IS_CAMERA");     public static final Property IsHidden = new Property(7, Boolean.class, "isHidden", false, "IS_HIDDEN");     public static final Property IsUserCreated = new Property(6, Boolean.class, "isUserCreated", false, "IS_USER_CREATED");     public static final Property Name = new Property(1, String.class, "name", false, "NAME");     public static final Property Source = new Property(4, Integer.class, "source", false, "SOURCE");     public static final Property UserType = new Property(2, String.class, "userType", false, "USER_TYPE"); }  public FolderDao(DaoConfig daoConfig) {     super(daoConfig); }  public FolderDao(DaoConfig daoConfig, DaoSession daoSession) {     super(daoConfig, daoSession);     this.daoSession = daoSession; } 

if you don't write public so occur error like Caused by: de.greenrobot.dao.DaoException: Could not init DAOConfig or static than Caused by: java.lang.NullPointerException: Attempt to read from field 'int de.greenrobot.dao.Property.ordinal' on a null object reference
