Green Dao无法启动DAOConfig

Question

我试图使用一个旧的Android应用程序，这是使用Green Dao这样的我们数据库也这个应用程序有味道，所以我编译，我安装apk但应用程序不开始它给出了这个例外：

Process: com.xxxx.boeufaujardin, PID: 20011 java.lang.RuntimeException: Unable to create application com.android.tools.fd.runtime.BootstrapApplication: de.greenrobot.dao.DaoException: Could not init DAOConfig

其余原因：

Caused by: java.lang.NullPointerException: Attempt to read from field 'int de.greenrobot.dao.Property.ordinal' on a null object reference
                                                       at de.greenrobot.dao.DaoConfig.reflectProperties(DaoConfig.java:99)

这是我的傻瓜：

------财产声明如下------

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;
}

如果你不写公共所以发生错误如由引起：de.greenrobot.dao.DaoException：无法初始化DAOConfig或静态而不是由引起：java.lang.NullPointerException：尝试从字段'int de.greenrobot.dao读取.Property.ordinal'在空对象引用上

我在下面添加了proguard规则。

-keep class xxx.dao.**{*;}

（xxx是我放置DAO类文件的packageName。）

这个对我有用。
