Wrote Complete: Support Multi-DB within OpenHelperManager. Need PR?

[jiongxuan]

Hi! I'm a Ormlite fan. We have many projects that use your products. Thanks a million!

Note: My English is not good. So I would speak as briefly as possible and use simple words.

Before

We used to refer your example HelloAndroidTwoDbs to suppport multi-db.

In addition, lacking any better idea :-(

After

Later, I tried to modify OpenHelerManager.

I created two new classes: OpenHelper and OpenHelpers. The role of OpenHelper is almost the same as the original OpenHelperManager, except became into a instance. OpenHelpers is used to manage all of the OpenHelper.

Just like:

Dao<City, Long> dao = OpenHelpers.getDao(context, CityHelper.class, City.class);
OpenHelpers.release(CityHelper.class);

These OrmLiteSqliteOpenHelper(s) match the ones all over the New OpenHelper(s). Fully comply with the rules!

Other usage:

CityHelper helper = OpenHelpers.getOrmliteHelper(context, CityHelper.class);
OpenHelper openHelper = OpenHelpers.get(CityHelper.class);

Advantage

It's very fruitful. These classes has approached the issue in a practical way. You won't need to reference any example, rewrite any extra code. Just need to use that one.

Testing

I wrote some simple unit-test code, have long time for our project. All operators have to verify is passed, ease of use!

Ending

If @j256 want to use these code, please tell me. I will improve the unit test, and PR to your project.

Awaiting for your reply. Thank you very much!

Sorry for the delay on this. Did you come up with a generic solution? We are getting ready to [finally] push 4.49 and I'd like to see if we can add support for this to 4.49 or maybe 4.50 which should come out soon after.

[WonderCsabo]

I also think we should support this, so the users do not have to write the solution which is in your examples, introducing potential bugs if they are not careful.
