Since you mentioned PhoneGap, how about Titanium Mobile?

It also can help you to build native applications across multiple platforms (Android and iOS), and you can leverage native C++ code in the application. It can also leverage file system APIs across multiple platforms.

Agreed. I'd LOVE to see openZIM support in a Wikipedia app. We need to make sure that our users can still access content even if their disconnected. I personally would love to be able to download a couple of collections in the openZim format and redistribute as needed. It would be really cool to download them trivially on a phone and then redistribute them to areas that may not have a faster internet connection but have a decent wifi connection.
Christian, Patrick and I can easily connect you with the PhoneGap team to help you out with this plug in. It would be good to get an early proof of concept out for the openZim and wikitech developers to play with. What do you say? Are you up for it?

We should definitely continue to talk about this and try to figure out the optimal approach.
Also, once the PhoneGap based Android application is developed it should be easy to fork and experiment with the various approaches described below.

Hi,
It would be really nice if offline (=zim) support was integrated in the official wikipedia app: The user could switch between online access
and
offline reading.
If I understand Tomasz correctly, it is planned to implement the
wikipedia app
with phonegap, so having zim support for phonegap would allow integration of offline
support
into the app. Therefore I think its a good idea to implement zim support for phone
gap.
Regarding the technical details there a basically to ways to implement
zim
support in phonegap:
- Using phonegap API. Theoretically device independent, but questionable
whether actually working with sufficient performance on all target platforms.
- As plugin: Implemented as a native component, with bindings to
phonegap.
I'd prefer the plugin approach. The additional effort of implementing
the zimlib
plugin for different platforms is not that high. The zimlib (and liblzma) is
already
available for C++ (STL): Symbian[1], Meego[2], Android (with NDK, cleaner is to use Java), iPhone (untested, may have some issues (see
[5]),
alternative would be to port to objective-C) and probably Bada Java (less mature than C++ implementation) : Android, Blackberry
and other
J2ME [3] (not sure whether possible on J2ME, but this is even more true
for
phonegap API approach) Porting needs only to be done to: C#: Windows Mobile Other: ? In addition the plugins for the platforms need to be written but this
shouldn't
be a too high effort. The zimlib is already pretty stable, so the maintenance effort for the
ports
should not be too bad.
An additional benefit of the plugin-approach is that the ported zimlibs
plugins
can also be used for native apps. (Besides having the plain zimlib, the plugin projects can be used as a
starting
point for new projects).
For the phonegap API approach zimlib must be ported to java script. As mentioned before I doubt that the javascript zimlib would work with
sufficient
performance on all (if any) . devices. See for example [4]
Best regards, Christian [1] Neither File (required for phonegap API approach) nor plugins
officially
supported in phonegap. However, should be pretty easy to add. (Either in official (=WRT) phonegap, or in QT port.
Probably
better in QT port). [2] Not supported by phonegap. However, should be possible to use QT
phonegap port.
[3] Not supported by phonegap. [4]

Hi,
is this maybe also useful for ZIM - to make ZIM readers which are working cross-platform?
As far as I understood phonegap is mainly a framework to create mobile apps based on HTML 5. At least the display of ZIM contents should be simple then as we just need a HTML widget for that. But what about libraries needed to read file contents, such as zimlib?
I
couldn't find out if Phonegap itself supports native file access (so we could re-implement ZIM features with that) or if it allows the use of native libraries.

Thanks for the super detailed write up Brion. I've been actively talking with the PhoneGap guys after doing some more research on this and it seems like a really good fit to have a consistent experience across a whole host of devices.
What were looking at is not necessarily a lot of depth in every single platform but a lot of horizontal range. Phonegap platform support beats out Titanium pretty easily there.
We'll be working a lot closer with the PhoneGap team going forward to quickly have something in the android store to start.
If anyone is interested in helping then we'll have plenty of opportunities to join in. Over the next weeks we'll be adding bugs and sending out more calls to get involved.

Titanium Appcelerator, which is another framework in that space, in
working
on StatusNet's iPhone& Android app.
Between the two I'd recommend PhoneGap for our usage as preferable
over
Titanium, but would appreciate more feedback from people who've done
fuller
PhoneGap work.
A few key differences:
PhoneGap models around extending a full-screen web view with
additional
JavaScript-accessible APIs to use device& OS capabilities (camera,
address
book, notifications, etc). This gives you few/no "native widgets" for
your
primary screens, but can make it relatively easy to create an
HTML/JS-based
web application that's extended with native abilities and can be
shipped
into native app stores.
Titanium was originally based on a similar model, but switched to a
native
widget bridging system, where your JavaScript code instantiates and manipulates objects which are bridged to native UI components and
such. This
can make your widgets look& feel more native, and can make some UI
bits
faster. But it also makes behavior less consistent between platforms;
many
widgets or features simply aren't available on all platforms, and
last I
checked there was basically *no* working support other than iOS and
Android.
(An early BlackBerry demo came out, was insufficient to do anything
we
needed, and never got updated that we saw.)
Since the Wikipedia app is mostly a webview and ...... maybe a menu? PhoneGap is probably a good choice. Titanium can also embed a
webview, but
it's a lot more work to deal with two levels of JS! PhoneGap has much broader device support, but be warned -- it'll use the native webview
on
each system, so JS and HTML/CSS support will still vary across
platforms.
Debugging in PhoneGap basically devolves to being able to debug a web application; various tools likehttp://phonegap.github.com/weinre/ can help with this (or if you code carefully you may get away debugging your
app in
your favorite desktop browser directly ;)
Titanium was always a bear to debug things in and basically came down
to
'watch the system log output in Android, that's the only place you'll actually see low-level errors'; this may be better now with their IDE support.
Titanium also pretty aggressively pushes their support& training
services
which I find offputting; their project build tool wants you to login
to
their 'cloud' stuff to let you hook up to their remote build&
analytics
services, which we didn't ever really use.
Support seemed to center on getting people to take training webinars
or
pointing people at the documentation and examples when they ask how
to do
something; I didn't find them very responsive about platform bugs or
missing
documentation except by contacting their couple of Android developers one-on-one in IRC to ask for merges -- which was usually a pretty
good
experience! Getting fixes for iOS merged was very difficult; I could
never
get ahold of their iOS developers directly, and they didn't seem to
be any
more responsive to low-level bugs we filed through their customer
support
system.
We had to build with a patched version of the iOS and Android
runtimes for
quite some time as there were serious bugs. On the plus side,
maintaining a
patched branch in git was very easy -- a lot of 'git pull origin
master' and
occasionally tidying up conflicts. Their source is all on github and
is easy
to fork and not too awful to build, at least for the mobile runtime.
Note that both PhoneGap and Titanium frameworks are open source&
hosted on
github, though both require a CLA to submit code upstream. (I have
signed
the Titanium CLA to submit patches to them last year; haven't done
for
PhoneGap yet.)
