Continuous Replication Issues

[Srinivas Tirumala]

Hi ,

Is there any listners or methods which will notify us the data changed in Couchbase server so that we can update on UI.

For example i changed project name from abc to abcd ,to update ui is there any listners which will listen for database changes.

Thanks,

srinivas

If you are running continuous replication from Couchbase Lite on iOS, there is a CBLDatabaseChangeNotification that is exposed publicly.

There are some details in this issue and in this commit.

There are quite a few ways:

• Observe kCBLDatabaseChangeNotification, as Andrew points out; or
• If you have a CBLDocument instance, observe kCBLDocumentChangeNotification posted by it; or
• If you have a CBLModel instance on a document, use KVO to observe property changes; or
• Start a CBLLiveQuery and use KVO to observe changes to its .rows property

On Android you can add ChangeListener's on the following objects:

* Database

* Document

* LiveQuery

which will be called back when these objects change due to underlying changes in the database.

After updating the latest version of CBL, I've noticed the .rows property is showing up as deprecated. What is the replacement property to observe?

It's only deprecated on CBLQuery, in favor of -run:. It's still valid on CBLLiveQuery, where it really does behave as an observable property, since CBLLiveQuery caches the rows.

Looks like you are using Ektorp, and in that case I believe the way to do it would be:

Thank's for reply
                   Is there any possibility  to do couhcdb on android continuous replication with out using Ektorp reference documention....

[Traun Leyden]

Yes the recommended approach is to use the latest code on the master branch:

https://github.com/couchbase/couchbase-lite-android

in which case you can use the native api and call Database.addChangeListener( .. )

Hello Traun, 

We've been eagerly waiting for beta 2 of Couchbase-lite Android. We need our iOS app(which uses CBL-iOS)  to be shipped as soon as possible in Android too. Repo milestones says beta 2 is past 5 days.  So, can we expect an official release anytime soon? Or github tag/release from which we can build it ourselves. This will help us to interact with our Android customers. We are expecting the CBL-Android equivalent to CBL-iOS (including helloWorld/API/tutorial documentations here).

TIA
Ajith

p.s we know you have been doing a great job trying to match up with iOS. Happy coding!

[Traun Leyden]

Hi Ajith,

Yes, you can expect that very soon, we are targeting this Friday (Jan 24), and it will include a HelloWorld demo app, API documentations, and tutorial docs.

Currently all of the last minute release related changes are happening on the stable branch, which will get merged back into master very soon.

Thanks for the kind words!

PLEASE do not hijack an existing thread to ask an unrelated question. Instead create a new thread (by composing a new email instead of hitting Reply.)

To retrieve an attachment from a document, try document.getCurrentRevision().getAttachment(attachmentName).
