Answer 1

To implement cascading while using ORMLite on Android you need to enable foreign key restraints as described here:

(API level > 16)

@Override
public void onOpen(SQLiteDatabase db){
    super.onOpen(db);
    if (!db.isReadOnly()){
        db.setForeignKeyConstraintsEnabled(true);
    }
}

For API level < 16 please read: Foreign key constraints in Android using SQLite? on Delete cascade

Then use columnDefinition annotation to define cascading deletes. Ex:

@DatabaseField(foreign = true,
columnDefinition = "integer references my_table(id) on delete cascade")
private MyTable table;

This is assuming the table/object name is "my_table", as described here: Creating foreign key constraints in ORMLite under SQLite
