I see no reason why Twitter should open source their app. They have absolutely no obligation to, and IMO, should not be pressured to do so just because some blogger feels that " there is an increasing divide between the UI patterns in their Android app versus the UI patterns that most developers work with".

The author says: "And lastly, Twitter should release this app because they said they would.".

Well, here is the statement from Twitter:

"We had a great time working with the Android team and are thrilled that Google will be open sourcing the code used in this app in the near future."

Saying Google will open source the code used in this app is completely different from saying "we ourselves will open source this app". It almost certainly means that Google will open source some small component that is used in the app. IMO, it is a bit of a leap to interpret that statement as saying "Twitter will open source the app".

IMO, in the absence of a more complete statement from Twitter regarding open sourcing their app, it is dishonest of the blogger to say Twitter "has no interest in making good on their word" when it seems like the blogger is putting words in Twitter's mouth. If a more explicit statement exists from Twitter, then the blogger should have cited that, instead of the slightly-but-not-really-ambiguous statement from Twitter that he used.

From what I've read, they have said it a few times.

Twitter has a solid collection of open source stuff on GitHub, i.e. the Twitter Bootstrap. Sure, maybe they don't have to release the ENTIRE app, but it would be ideal if they could contribute some of their work (such as the UI patterns) back to the community.

I've searched for more info on this, and each time it comes back to that one quote I posted. That quote, IMO, absolutely is not saying Twitter will open source their app. It sounds to me like they were saying Google would open source some code used in the app.

Maybe I'm missing something, but I really do not see that quote the same way the OP does.

Most of Facebook's Android app is just a web view as is their iPad app and probably their iPhone app too. I wouldn't be surprised if the Twitter Android app is also a web view.

The Facebook app for Android does a decent job with pull to refresh.

nt_mark2• 15 years ago

I haven't checked this out, all I'm saying is it looks a LOT like http://mobile.twitter.com. Same border, same pull down to refresh. Mobile web FTW.

"You'll notice that Twitter is no longer using the standard Android ListActivity. There is a slight border around this list right now, which is VERY new to Android apps."

A ListView with some layout_margin ? Am I missing something special ?

chuinard3• 15 years ago

I always felt the ListView needed to expand the screen. I could be wrong though, this might just be a layout_marginLeft or layout_paddingLeft attribute. Either way, it is a very new pattern for Android apps. You'll also notice the rounded corners, which I don't think come naturally with a ListView margin.

I've made this app : https://market.android.com/details?id=com.cardiweb.carrefour... See the third screenshot : https://lh6.ggpht.com/FOyDJtPGapRpBk0zSpFcXVUu45zHEY5OTaHfto...

The list at the bottom is just a RelativeLayout, with some rounded corners. Wrap this in a ScrollView, and voila.

I've seen it a few times (though I can't recall any examples immediately) in the market, and implemented it once or twice.

Usually it's in apps that are ported from iOS with minimal consideration for Android user interface expectations, because it's a much more standard design pattern there.

nutjob123• 15 years ago

Yeah i can think of a number of ways to do this with padding or layout margins and then setting a shape drawable or 9 patch for as the backround of the list or its container. In fact i just checked and i have done this for a couple published apps. The pull to refresh feature is interesting. I would be tempted to mess with the sliding door class for a solution.

RobAtticus• 15 years ago

I don't see it either. There is nothing in that layout that I don't know how to implement, so unless I'm missing something more subtle, I don't think it's anything new.

Pewpewarrows• 15 years ago

I'm sure that's how you'd go about doing it using ListView. But isn't the new Twitter app just a wrapper around their mobile browser UI?

Warning: the "pull to update" feature is patented by Apple.

sootzoo• 15 years ago

which hasn't stopped anyone from using it in their own apps anyway (e.g. Facebook)

thetrendycyborg• 15 years ago

the "pull to update" pattern was invented by the maker of the Tweetie app, who was hired by Twitter.

martingordon• 15 years ago

This is simply not true.

Pull to Refresh was invented by Loren Brichter, author of the Tweetie app for iPhone, and he filed a patent for it (http://gorumors.com/twitter-patent-drag-to-refresh/2754292). As the article states, the patent application was submitted the day before Tweetie was acquired by Twitter, so we don't know for sure if Loren or Twitter own it, but it sure isn't Apple.

adestefan• 15 years ago

So the argument is basically, "I want my app to look like yours; so open source it for me to steal the layout." Is this really how people write software these days?

speakbin• 15 years ago

It's better for the overall ecosystem. Higher quality apps means more time spent on your phone. If we can't duplicate the features of the app that aren't domain-specific, it results in an overall worse feel for the end user.

lnanek• 15 years ago

Hasn't Twitter straight out requested that people not develop more clients? Example article: http://www.readwriteweb.com/archives/twitter_tells_developer...

Open sourcing it would just help people to publish slightly different versions with little effort - which is what they say they don't want...

jc4p• 15 years ago

I understand that Twitter said they were going to open source their application a very long time ago, but I've found that if I am interested on how they do anything the folks on the official Android irc channel are very helpful. Their initial version of the application used the dashboard interface that google revealed as the future of Android UI but there was absolutely no example code on how to do it until the recent Google I/O application that was open sourced. The people on the IRC channel helped me replicate that very quickly.

If you were angry enough to write a blog post, you could've also looked into decompiling the code and seeing how they do it yourself. If you use dex2jar:

http://code.google.com/p/dex2jar/

you can see that the view you're discussing is a custom ListView they made called RefreshableListView which actually does extend ListView so it is technically a ListView.
