启用proguard时，sqlite中的where子句会使我的应用程序崩溃

Question

我正在开发一个使用ORMlite库访问sqlite数据库的Android应用程序。方案如下。

1. 我的应用程序在调试模式下工作正常，即没有模糊处理。
2. 当我启用proguard时，应用程序崩溃在我使用WHERE子句从sqlite数据库访问数据的行。
3. 如果我从代码中删除WHERE子句部分，即使在混淆之后，应用程序也能正常运行。

请查看我的proguard-project.txt和源代码。

-keep class com.j256.**
-keepclassmembers class com.j256.** { *; }
-keep enum com.j256.**
-keepclassmembers enum com.j256.** { *; }
-keep interface com.j256.**
-keepclassmembers interface com.j256.** { *; }

-keep class com.j256.** {
    *;
}

-keepclassmembers class * {
public <init>(android.content.Context);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * implements android.os.Parcelable {
    static android.os.Parcelable$Creator CREATOR;
}

            Dao<Note, Integer> noteDao = ORMManager.getInstance(
                    getBaseContext()).getNoteDao();

            QueryBuilder<Note, Integer> queryBuilder = noteDao.queryBuilder();

//          queryBuilder.where().eq("category", Note.NOTE_CATEGORY_PERSONAL); // CRASHES WHEN ENABLED
            PreparedQuery<Note> preparedQuery = queryBuilder.prepare();
            List<Note> noteList = noteDao.query(preparedQuery);
            NoteGridListAdapter adapter = new NoteGridListAdapter(this, noteList, NOTE_TYPE.PERSONAL, this);

            grid_personal.setAdapter(adapter);
            grid_personal.setExpanded(true);

        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
