Android with Remote Couch
Does anyone know whether a hosted (remote couch) is accessible from an
Android app, via an XHR call? I mean from a native Android app, not
via the web browser, which should work anyway.
I have a web app I would like to port to Android (using PhoneGap).
Installing a local couch means that users cannot share game hi-scores,
so hosted would be better. Phones/Tablets are online
anyway.
Is anybody here developing Android apps which talk to CouchDB?
Thanks,
Marcus

Yes, its not a problem to consume a web service from a native Android app.

Marcus,
Not sure I saw this in the dialog, but you can try:
allow_jsonp = true
On your iriscouch configuration. Log in to futon as admin and change.

Yes, in fact the script is not seen and Android complains about it. So
the scripts have to be in the same place as the HTML file.

I'm not sure it's only a cross-domain issue. I use HTML5's Postmessage
to work with cross-domain policies. That worked great when the scripts
are in the couch and need to talk to another domain (for extra PHP
stuff). It's a bit mind-boggling for a while, but it works, the
Postmessage jquery plugin even supports old IE versions.
I'll ask on the PhoneGap list, but I wasn't sure how much this is a
couch db issue.
Has anyone tried talking to a couch from a web app stored locally on
your PC? I mean either just loading the static HTML file in the
browser (now web server), or running a web server as localhost?
Thanks,
Marcus

Putting couch.js on the server wouldn't bypass the cross-domain problem.
I would suggest ignoring anything mobile and seeing how a web page would
bypass the cross-domain problem to get to CouchDB, since that's the problem
you're having (just that it's a mobile web page). IIRC, there was a
discussion on this list about it, and someone wrote a Node.js proxy for it,
but I only vaguely remember it.
Also, sometimes PhoneGap will bypass the cross-domain restriction. For
example, on iOS 4, you can get remote JSON all day long, but on iOS 3, you
have to use JSONP.

You might be better off asking on the PhoneGap list?

It's an Android app which needs to query a hosted/remote couch via Javascript.
I'm using PhoneGap, so the code is Javascript, HTML, CSS, but runs as
an Android app.
Thanks,

Sorry are you writing a web app that runs locally?

I need a bit of help accessing my hosted couch from Android please.
Where should couch.js be? Locally inside the Android app, or on the
remotely hosted server where the db is?
My first XHR query to the couch is to get the session data with
couch.js. I'm getting an Ajax error from jQuery while querying the
couch:
TypeError: Result of expression 'resp' [null] is not an object at
jquery.couch.js:81
I think the javascript files have to be local to the app, but that
means couch.js cannot talk to the remote couch due to cross-domain
restrictions. A local javascript file cannot talk to a remote script.
How are you guys talking to your hosted couch from Android? Are you
using couch.js or another method?
Many Thanks,
Marcus

That should be all you need unless your app needs to read local data (e.g.
contacts) or location or sensor info, etc.

Thanks, Scott and Ajai, are there any permissions or user interactions
necessary apart from the basic Internet permission below?
uses-permission android:name="android.permission.INTERNET"

I regularly make HTTP calls from my android applications to Cloudant (hosted
couch).
The beauty of REST.
