ORM on Android SQLite and database scheme [closed]

Answer 1

Below is how I do it with SORMA - An Android Content Provider solution.

1. Map your Java POJO to database table:

   @Table(
   name="contact",
   keyColumn="id",
   autoId=true,
   create="create table if not exists contact (" 
   + " id INTEGER primary key autoincrement"
   + ", firstName text"
   + ", lastName text"
   + ", married tinyint"
   + ")"
   )
   public class Contact {
   private Integer id;
   private String firstName;
   private String lastName;
   private boolean married;
   ......
   

2. Create content provider class:

   import com.gaoshin.sorma.annotation.ContentProvider;
   import com.gaoshin.sorma.annotation.SormaContentProvider;
   
   @ContentProvider(
       version = 1,
       mappingClasses = {
           Contact.class,
           Phone.class 
       }
   )
   public class AddressBookContentProvider extends SormaContentProvider {
   }
   

3. Define content provider in the AndroidManifest.xml:

4. Use the content provider:

   sorma = SORMA.getInstance(getBaseContext(), AddressBookContentProvider.class);
   
   // insert contact
   Contact contact = new Contact();
   contact.setFirstName("fname1");
   contact.setLastName("lname1");
   sorma.insert(contact);
   

Done!
