You need to ask if you want an Android to vibrate

Saturday, November 13th, 2010

I posted a few days ago about a new little app I stuck in the Android Market. An error report appeared from the app in the Market last night that I thought was interesting.

The app does some stuff in the background then when it’s finished, it sticks a notification in the top status bar. In my code, I just use the default notification settings – LED flash, vibrate, etc. And on every Android I’ve tested it on, it’s been fine.

But for one user, it caused the app to crash:

Exception class java.lang.SecurityException

UK Traffic Checker now in the Android Market

Monday, June 14th, 2010

Update: (April 2011) The app is no longer available

UK Traffic Checker for AndroidMy last post was a bit of a clue, but I still thought it was worth a mini-announcement that “UK Traffic Checker” is now available in the Android Market.

I wrote about the basic idea for the app when I first hacked it together, but to summarise it’s a mobile app that checks for roadworks or other traffic incidents on UK roads for a specific journey. Tell it two places, it will work out the route between them, and check that route for known problems.

And if you give it your schedule, it can automatically check traffic for you – with support for both one-off and repeating journeys. So if you have a regular commute, you can give it the details and it will check your route to work for you in the morning while you get ready, without you needing to remember to ask.

Releasing apps in the Android Market app store

Monday, June 14th, 2010

I’ve just added my first app to the Android Market app store, so I thought I’d write a quick post to share what is involved.

Note: This post isn’t aimed at mobile devs. The process is documented clearly enough that there really isn’t any need. Rather, this was more written at people who are probably never going to write and submit an app to a mobile app store, but who might have an idle curiosity about what is involved getting an app from a developer’s workstation to the app store.

Step 1 – Write the code

The Android plugin for Eclipse gives you nice integration for publishing.

You can right-click on the project, choose “Export Signed Application Package” and the wizard spits out a signed file ready for publishing.


Step 2 – Register with Android

You visit the Market site at http://market.android.com/publish/signup and pay your $25 to register with Android as a developer. For me, it worked out to a bit over £17.
