Really lightweight orm for Android, 17kb.

bc-lite-orm

This is a very lightweight (17kb for now) ORM for Android. Use this when you want to keep your app size down and just want to store peristant data without all the features of a full ORM.

How to Use

You will need a class that extends BcSQLiteOpenHelper

public class DatabaseHelper extends BcSQLiteOpenHelper {
  
	public DatabaseHelper(Context context) {
		super(context, "Test.db", null, 1);
	}

	@Override
	public void onCreate(SQLiteDatabase db) {
		TableUtil.createTable(db, Person.class); // Creates the table
	}

	@Override
	public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
		
	}
}

The Person class looks like this

@PersistantObject
public class Person {
  @PersistantField(columnName = "person_name") // optional
	public String name;
	@PersistantField(id = true) // could also be generatedId
	public int age;
}

Creating a Dao would go like this: BcDao<Person, Integer> bcDao = new BcDao<Person, Integer>(Person.class);

Then you could query the table with List<Person> people = bcDao.queryBuilder().lt("age", "" + 20).orderBy("age", false).limit(5).execute();

It also has the basic methods of: insert insertMany update updateMany delete deleteMany
