This post is intended to go through the process of writing and publishing an app. It will be a high-level introduction. The idea is that future posts that will dig into specific topics in depth. This post will be updated to link to those future posts as an index of mobile development topics. The app I’m describing is VicinityBuzz and it’s available here.
While I had been thinking about writing a mobile application for a while, I needed an idea to stick with to completion. The app stores are relatively young, but they are fairly saturated, and bringing something new to the table was a challenge. Recently I read Eric Ries’ The Lean Startup and I do like the idea of MVP(Minimum Viable Product), so I didn’t feel the need to have a telephone book of requirements. I was just looking to have an original idea for the app stores.
In the case of VicinityBuzz, I have always felt that there are not enough good ways to search social media, particularly by location. There are social media sites like FourSquare solely dedicated to location, but I’m referring to something else. Using networks where content is the reason (not location) but by location. For instance, at a conference, users often hashtag their tweets with the name of the conference. But not always. And the hashtag will draw attention from people not at the conference. That’s fine, and there can be useful conversation by just using the hashtag, but what if I want to see posts of all users that are actually at the location.
This is particularly true of news events. On the day of the shootings at Chardon High School, I used the application to see what students and families in the area were posting about. They were each telling their own version of the story. It was heartbreaking and much more informative and up to date than the news being released to the public. Hashtags were useless in this case, for two reasons. First, the students weren’t hashtagging their posts, they didn’t need to. They were posting to their real-life friends and thus already connected on twitter. Second, the tag was full of a lot of the reaction from the public around the globe. That was interesting too, but it wasn’t was I looking for. I wanted facts and eye-witness accounts. It was like CNN’s iReport, but on steroids.
Essentially PhoneGap provides project templates for your platform (Android, iOS, WP7, and more) that create a shell of an application that hosts a browser control. All of your files go in a directory (like resources) and get loaded up by the browser control.
Using PhoneGap gives me a version that is easily ported to Android and WinPhone 7. Although those markets lag Apple’s AppStore in terms of developer revenue, I want to cast the widest net possible with this application for obvious financial reasons, and also to learn. The more feedback I can get on the application, the better I can make it.
At some point I may go ahead and do a native rewrite. But for now, I’m very happy with what is possible in PhoneGap and jQuery mobile.
One note: If I had to do this over again, I would have simply started with jQuery mobile. It’s not that hard to get started with as the docs are great, and it’s best to just start down that path.
App Store Submission
Thus far, I can only speak to the Apple Store submission process. After going through the steps provisioning portal, it was fairly easy to test the app on a device. In order to submit to Apple, you then create a profile for the application (screenshots, contracts, payment details, etc) and submit a signed binary to Apple for review. The process of signing a binary for release can be a little tricky, but the walk-through on Apple’s developer portal helps a lot.
One thing to note: Apple requires you have a support page. I stole an idea from the Trello folks, and used a public trello board for this purpose. It took less than 5 minutes to setup.
I created a basic web page with a description of the application. Apple has a page for making the link to their store. If you are interested in opening the store automatically, either see the options in this stackoverflow post, or add the query paramter “ls=1” to the url you get from the link maker.
Apple just announced “the new iPad” so I have to do some updating to support that. I haven’t read the new docs, but I assume this means a high-res iPad splash screen and icon. All of my other assets are web assets and scale accordingly.
My next steps are to add a simpler user workflow, a refresh button to update your current search, and add some social networks like Facebook and Instagram.
After that, I’m going to start porting to Android and WinPhone 7. Since the application is already written, it should be as simple as getting a PhoneGap project running for each environment. I have also considered the Mac App Store and the upcoming Win 8 Marketplace for desktop application versions.
Finally, I’ll blog more in depth about some of the topics covered, and provide links to those posts on this page. Mobile development is rewarding, but can be challenging for those coming from a web or desktop background. I’d like to pass on some of the things I learned so that others working in mobile can save some time.
Feel free to provide feedback and questions if you have something in particular you’d like me to cover. And checkout the application!
