Plus you have cross scripting accross domains can of worms as well..

Its one reason why even if I am embedding most of my app in web code
via webview I am still using native side to
do the app password and OAUTH permissions at start up to  void such
can of worms

I suspect that just blindly supporting HTML-based gadgets in the home screen
would be less than desirable.  This would mean having (multiple) instances
of the web browser running in the home screen process, displaying gadgets
that were designed purely for a desktop environment -- if you look at
existing gadgets there are very few that will take less than the full size
of the available screen, if they even fit on the screen at all.  And you can
be sure that the vast majority aren't going to be very memory efficient,
running in a web browser in a process that also has a key part of the global
user interaction so wants to remain running as much as possible.  Plus they
are designed to be interacted with using a mouse, and would now be running
in an environment where you use your finger and inside of a container where
finger gestures are already dedicated to being able to scroll and drag.

So it's not really so straight-forward. :}

[android-developers] Re: Why didn't google provide APIs for desktop widgets?

2009-02-24 Thread Al Sutton 

I'm starting to see the can of worms. I'd assumed there was already 
something in place for handling permission separation and that access 
was locked down, I hadn't realised that the current home widgets were so 
tightly integrated.

I'm guessing unless the permission model can be brought down to Thread 
level granularity then some form of either providing the widget with a 
Canvas or using IPC calls back from the widget are the only way to go.

No, that's the point. You don't want to run foreign code (the widget) in
Home because it would then be able to use Home's multiple permissions. There
are several approaches to solve this. One is to rely on remote views, like
in the status bar, but it limits what the widgets can do.

2009-02-24 Thread Al Sutton 

Just to go a bit further on this, I'd hope you'd be implementing at 
least a subset of http://desktop.google.com/plugins/

It's Google code, it'd bring a lot of widgets/gadgets onto Android in a 
short time frame, and would lessen the learning curve for many people.
