java - How to add initial data for DB using GreenDao in android? -

i have been answer insert initial data in native mode

how add initial data sqlite database?

how can same result using green dao?

this application class

public class app extends application{       @override     public void oncreate() {          super.oncreate();         daomaster.devopenhelper helper = new daomaster.devopenhelper(this,"images-bd",null);         sqlitedatabase db = helper.getwritabledatabase();         daomaster daomaster = new daomaster(db);         daosession daosession = daomaster.newsession();        }  } 

you can create class extends daomaster , run queries inside oncreate method:

public class customdaomaster extends daomaster {     public customdaomaster(sqlitedatabase db) {         super(db);     }      public static class openhelper extends daomaster.openhelper {         public openhelper(context context, string name, sqlitedatabase.cursorfactory factory) {             super(context, name, factory);         }          @override         public void oncreate(sqlitedatabase db) {             super.oncreate(db);             db.execsql("insert mytable values('foo')");             db.execsql("insert mytable values('bar')");         }     } } 

so, in application class, use instance of class:

public class app extends application {      @override     public void oncreate() {         super.oncreate();         customdaomaster.openhelper helper = new customdaomaster.openhelper(this, "images-bd", null);         sqlitedatabase db = helper.getwritabledatabase();         customdaomaster daomaster = new customdaomaster(db);         daosession daosession = daomaster.newsession();     } }
