Which is the best ORM tool available for Android? I am seeing ORMlite and ActiveAndroid are the most discussed across and a friend of mine suggested me to use GreenDAO. So looking for some knowledge resource which can help me in Decision Making? Features I am looking to judge are freely available (open source), good documentation, active forums, stable version available, etc, which ever required for developer. I would suggest ORMlite its open source freeware & has good documentation also it support java as well as android. It has good developer support & many application running on ORMlite

I have seen another question about schema upgrade/migration using green dao ( here ) There are lots of links in that answer for a good pattern to use when doing schema upgrades - however there are no examples of what you actually do to your data to migrate it properly and I'm having trouble finding anything. In my case, my migration is incredibly straight forward - I do not wish to transform any existing data, I simply need to add some new tables to my schema, which I suspect is a fairly common situation. What is the easiest way to add new tables to your schema without deleting data your users

I'm looking for a clear step-by-step explanation on how to import GreenDao in Android Studio. I've used it before in AS, but failed to get it to work again. There are some tutorials out there, but they don't seem to apply to the latest version of AS. When I clone from github, I get a example project stuff etc. Is there a way to install GreenDaoGenerator without these extras? Just looking for an up-to-date step-by-step explanation. Update: I suggest using Realm.io now! Check it out! :-) Any help would be appreciated! Tested on Android Studio 2.0 With Android Studio 0.6.1+ (and possibly earlier)

I'm evaluating GreenDAO for consideration in a commercial Android app I will be working on and wanted to determine the migration path for schema updates. Am I correct in asserting that I would have to write a custom OpenHelper which provides the onUpdate() and extracts transforms and stores data according to the new schema? This assumption raises some interesting questions around ordering of calls and partitioning of responsibility. I have not been able to find any documentation around schema update and data migration for GreenDAO. Here are a bunch of blog articles I have written on this topic

I am using GreenDao orm library for creating database, it works good with the First sample for Creating Database, from within the code. Now the problem is I can't find any documentation or anything related to the Database copying from Assets Folder to the databases inside memory. The accepted answer provides a solution but it's only partially correct. Check out the class I posted below. This is an extension of greenDao's OpenHelper class. Below that is an example of it's use and how you can use it instead of OpenHelper or DevOpenHelper to manage the copy of your sqlite database. package com

一、GreenDao的介绍 GreenDAO是一个开源的Android ORM(“对象/关系映射”)，通过ORM（称为“对象/关系映射”），节省了我们在数据库开发过程的时间！ 通过GreenDao，我们可以更快速的操作数据库，我们可以使用简单的面相对象的API来存储，更新，删除和查询Java对象。 GreenDao的优缺点？ 1. 高性能 2. 易于使用的强大API，涵盖关系和连接 3. 最小的内存消耗 4. 库大小（<100KB）以保持较低的构建时间并避免65k方法限制 5. 数据库加密：greenDAO支持SQLCipher，以确保用户的数据安全; GreenDao的核心类 GreenDao的核心类有三个：分别是DaoMaster, DaoSession, XXXDao，这三个类都会自动创建，无需自己编写创建！ DaoMaster:：DaoMaster保存数据库对象并管理特定模式的DAO类。它有静态方法来创建表或删除它们。它的内部类OpenHelper和DevOpenHelper是SQLiteOpenHelper实现，它们在SQLite数据库中创建模式。 DaoSession：管理特定模式的所有可用DAO对象，您可以使用其中一个getter方法获取该对象。DaoSession还提供了一些通用的持久性方法，如实体的插入，加载，更新，刷新和删除。 XXXDao：数据访问对象（DAO
