Re: [android-developers] Phone for development

2011-04-27 Thread Pepijn Van Eeckhoudt

I agree with that review. As I already said in the set of devices I have 
available, that one's my 'favorite'.


A couple of my colleagues have one for personal use as well and are very 
happy with it. BTW, there's also a revamped 'S' version of the desire 
which is a gingerbread device. It's probably a bit more expensive than 
the regular desire though.

Accoding the the last section called "Wrap-up" the first paragraph reads:

The Desire is yet another fine piece of work from HTC -- build quality 
is top notch as usual, and there's little to complain about the 
software except for the Flash performance. Some may argue that the 
Desire lacks freshness since the Nexus One's already shown it all, but 
we'd disagree -- at the end of the day it's mainly about the software 
andservice 
, 
plus the Desire is available from more carriers to begin with (outside 
the US, anyway).


If I were looking into buy the phone given the review I wouldn't feel 
bad about buying it, but that's me.

Is the Desire a good choice?

Thanks Pepijn. That helps a lot. I'll most probably do with a HTC now.

Thanks everyone.

Okay. I'll check that out. Still can someone suggest a reasonably

Since no one's giving you any advice I'll give it a try ;)

The dev phones I use myself are Motorola Milestone XT720, HTC Desire, 
Samsung Galaxy S and a Google Nexus S; one for each OS revision. I 
know these are all high-end devices, but I can try to extrapolate my 
experience with those.
Objectively, they're all fairly similar for development purposes. I 
don't use these phones for anything besides testing so I can't comment 
on any Android customizations each vendor might have made. 
Subjectively, I prefer the HTC the most in terms of feel and build 
quality. HTC seems to do a pretty good with their OS updates as well 
and they actually use OTA updates rather than requiring some buggy 
proprietary tool.


If you stick with HTC the only model they seem to have in the 230 euro 
/ Rp. 15000 price range is the wildfire. The wildfire is listed in 
Belgium at 229 euro and the wildfire S at 289 euro. The first one is a 
Froyo device, the second one Gingerbread.


I don't know about the specific Samsung model you mentioned, but the 
Galaxy and Nexus are pretty good too FWIW. The only downsides to 
Samsung IMO is that you have to use Kies to perform upgrades which can 
be a pain and they feel rather flimsy, plasticy. The HTC has a 
sturdier feel to it.


Hope this helps,

Pepijn

OK. I think this separation between "dock mode" and "dock event" is a
bit confusing, I expected those to belong together, even if only
"emulated". But of course there might be situations where this
separation is useful...

So if I understood this correctly:
ACTION_DOCK_EVENT is for apps that want to respond to "real" dock
changes, like showing some activity, notification, or toast. It's
supported since Android 2.0, and can't be emulated since 2.2.
UiModeManager and Configuration.uiMode allow to query the current
mode, which is the way to go if the app should e.g. show different
layouts depending on the dock mode, but only exists since Android 2.2.
UiModeManager also allows to (de)activate the car mode.
Right?

Re: [android-developers] How is your app selling on the Amazon Appstore?

Very slow. It took ages (2-3 weeks?, can't be sure because there is
no timeline for status changes) to get approved. Hopefully updates
will get approved faster. Not exactly 'something for nothing', because
I had to create a separate build for the Amazon store since my app links
to another app, and I had to disable that until the other app is approved,
which only happened a few days ago. Now I have to replace Android
market links with Amazon links and release an update.

All three apps are free, but maybe the problem is that the Amazon
store is US only, and my apps are mostly popular in Asia. On the
other hand, the reference category has less than 100 apps, so
less competition :)

To sum up, I'm still not convinced that publishing to Amazon is
worth the trouble. Since it's free for a year, there's still some time
to see what happens.

[android-developers] What exactly happens during an upgrade?

2011-04-27 Thread Robert Macaulay

I have Acra in my app to report on crashes(I will be removing it in
favor of the market one soon). I've recently changed the form that it
posts to during an upgrade(so the new app version will post to the new
form, the old version will remain on the old form). However, I've
witnessed old code, throwing an exception about resources being null,
being reported to the new form. Acra attaches an uncaughtException
Handler to the application class. In this case, since I've switched
destination forms, it implies that Android is replacing the code in
place in the same process. The exceptions I get are in the old code,
usually accessing resources from the context.

An example is:
onCreate() in my launch activity sets up a tab host. It assigns a
selectorDrawable to the tab(an xml resource, referring to 2 valid png
files, all in the drawable directory). It gets a ResourceNotFound
Exception - stack trace at the end. The line numbers indicate it is
being thrown in old code. However, the user has installed the new
version since I see the exception on the new form. It seems that there
is a race condition during upgrades where pieces of the old app are
still around while the new one is being placed in.

I've also seen very similar things in a Service that has an AsyncTask
that gets the AppWidgetManager.getInstance(this). In this case, it
throws an NPE in there - stack also at end..

In the end, a solution would be to enforce a new process for the new
instance of the app. Is this possible? If that is what happens, how is
the code being mingled at runtime? Could the user be launching my app
while it is "installing", and thus get pieces of the old one still?

Thanks
Robert
