Mobile Web Europe Conference- Key Takeaways

LONDON -It will take me a while to assimiliate 3-days worth of information on where we are headed with Mobile Web today but some of the key questions that were addressed were:

-Should we head towards a 'one-web' concept (same for PC and mobile as per the Convergence theorists) or more towards two distinct webs (as advocated in part by .mobi), one optimised for PC and the other optimised for Mobile (and the maligned 'small screen')?

-With much talk of Mobile Social Networks, shouldn't companies in this space realise that they need to focus on hosting the network instead of managing it? This was a great point mentioned by Priya Prakash of Flirtomatic, who also went on to state that a great host should facilitate conversations and act more as a matchmaker so that new contacts can be made

-Alfie Dennen from moblog:tech was of the opinion that the iphone has taken the industry a step back (due to its closed environment), something overlooked amongst the mass hysteria surrounding it

-Kashif Hassan, from ooober, made an excellent point about content, suggesting that given the sameness of many Mobile Social Networks, it is the presence of branded content that will make the difference...witness HBO's Entourage feature on the whrrl site

Announcing the Android 1.0 SDK, release 1

About this time last year, my colleagues and I were preparing for the first of the "early look" SDK releases. I remember being a little freaked out—November 12 was starting to sound awfully close! But I think I can safely speak for the entire Android team when I say that we were all very excited about that upcoming release. In the year since, we've run and concluded the first Android Developer Challenge, given away $5,000,000, released more SDK builds, and worked with our partners to prepare the first device for users. It's been quite the whirlwind of a year.

In one of those strange cosmic symmetries, here we are a year later, and we're once again very excited about an upcoming release. I'm referring, of course, to the first Android-powered device that our colleagues at T-Mobile have just announced—the T-Mobile G1. We can't wait to see our hard work on store shelves and in the hands of users, but today we're almost as excited because we're announcing the brand-new Android 1.0 SDK, release 1.

Yes, that means we're officially at 1.0. Of course the SDK won't remain static—we'll keep improving the tools by adding features and fixing bugs. But now developers can rely on the APIs in the SDK, and can update their applications to run on Android 1.0-compatible devices. The Android Market beta will also launch with the T-Mobile G1, providing developers an easy and open way to distribute their applications on that and later devices. I've already seen a lot of applications that have me stoked, and I can't wait to see things really come together as developers cross that final mile to prepare their applications for Android 1.0.

So what's next for us? Well, we'll keep working on the SDK, as I said. But we're also working hard with our partners in the Open Handset Alliance on the open-source release, with the aim of making the code available in the fourth quarter. The second Android Developer Challenge is also on the horizon—watch this space for more details. We're also already working on the future of the Android platform, and on more devices. We've updated the Developer Roadmap, and we'll keep updating it as more information becomes available.

It has indeed been quite an exciting road to get to where we are today. The road stretches on ahead though, and we're not slowing down for a moment. I look forward to meeting and working with many of you developers out there—and trying out your apps on my phone!

Happy Coding!

Panoramio

The Panoramio web site has a great collection of photos from all over the world, and they also have a very convenient web API. I thought it would be a lot of fun to use Android to access this content while you are out walking around – and especially to have Android find interesting photos based on your current location. The resulting open source application is now available in the apps-for-android project.

The application starts by showing your current location in a custom MapView. You can pan and zoom this map to choose the area you want to search.

Once you have selected a search area, the application downloads thumbnails of the most popular photos taken within that area:

You can tap on an item to see more details.

From here you can use the menu to find more pictures by the same photographer or to see the original photo on the Panoramio site. My two favorite features, though, help you find the location of the photo in the real world. You can show the location on the map along with your current location:

Or, you can bring up a radar view that uses the compass and GPS to show you the location of the photo in relation to your own location:

I thought that other applications might want to use the radar view for their own purposes ("find me the nearest taqueria"), so I split that into its own package. You can find the source for that in the Radar project. Of course, you don't need the source in order to use this feature. Because of Android's component architecture, all you need to do us use an Intent:

Intent i = new Intent("com.google.android.radar.SHOW_RADAR");

i.putExtra("latitude", 37.422f);

i.putExtra("longitude", -122.084f);

startActivity(i);


The code for these applications is not very long, but they are a good example of how to use a number of Android's location APIs:

• Using an embedded MapView along with a MyLocationOverlay to plot your current location. The is also a custom class which extends Overlay to draw the Panoramio pushpin.
• Using the SensorManager to get our compass heading.
• Using the LocationManager to determine our current location
