Have you ever wanted to have a better idea of what’s the best source of your app installs? There’s information around the web on how to do it, but spread out over various sites, so I decided to write this post to consolidate the information.
Have you ever run into the error “Incorrect AVA format” when trying to sign an Android APK with a new key? It turns out this useless error more than likely means that you have used some illegal character in the signing data. In my case, I had used a comma in the company name which isn’t allowed for some reason. Just remove any extra characters and you should be good to go!
To help make our Android applications look even more professional, we can include HTML formatted text and display it in a WebView. Here’s the simplest way I’ve found to have local HTML, image and style files and display them. This is the same process I use to display help in Grandma Jong.
The Android Icon Design Guidelines have been updated to describe the latest design styles of iconography in versions 2.0+. The styles have changed dramatically from pre-2.0 days, so be sure to read the whole document.
There are also some nice Photoshop templates that can be download from here.

It has been a long couple of months from before Thanksgiving straight through Christmas and New Years and I was very busy during those times. I didn’t get a whole lot done on anything Android related, including working much on my first app to be published to the Android Market, titled Grandma Jong.
I’m really excited about attending the third local BarCamp in DC tomorrow! Yep, we’re already on our third one here locally (not to mention all the others happening in the Baltimore-Washington D.C. area). I’m planning on co-presenting on Android development with Zvi Band. I’ll be showing a simple graphical app with animation and touch screen input.
I’m also using this opportunity to launch the first in a series of articles on Android development, gradually improving this simple app into something useable in a real app involving animations and graphics. Stay tuned, I’ll be posting the first article here sometime next week.
Version 1.6 of the Android SDK has been released to developers. Though this isn’t a major release, there are quite a few tasty updates that I’m looking forward to (both as a user and a developer).
