There are a lot of ORM for Android. Previously, I have used Ormlite. That is quite good. I got a new personal project of Android App. This is a good to look around new framework I can use. I found Google has their ORM layer. That is not form the standard SDK. This ORM is from the Android Architecture Components. That is quite modern, and similar with others. It used annotations like this to define the mapping

Code

But the Dao is a strange

public  interface DrawingEventDao {
    @Query("SELECT * FROM drawEvents")
    List loadAll();
}

Because it is a ORM of sqlite. You still need to write the SQL like this. That is the things I do not really like. Maybe I have been LINQ for too long. That is not easy to go back the SQL. But that is still much better than connecting with Sqlite
