TL;DR This article fills in some of the gaps in the official docs and add rationale to why you should consider moving your app to a non-human Google account.
Google offers the ability to move/transfer one of many apps from one Google account to another. But before you transfer highly recommend reading the official docs on how to transfer apps to a different developer account here.
Are you using your personal Google account for apps?
If your app(s) are associated with your personal Google account you run the risk of having your access to Gmail, Google Photos, Drive blocked if Google Play account is suspended due to a breach of Play content policy. The thought of losing access to my emails, family photos is a very frightening prospect. You might think you’ll never be in breach and maybe you’re right? but remember the Play content policy is frequently updated and you have to ask yourself how closely you read the updates. I ran into policy breaches a few times and none of the apps I’ve released are particularly risky. The first app that I wrote to get my first Android job was a wallpaper changer based geotagged Flickr photos and user’s location. It was pulled due to copyright infringement (I mistakenly used Flickr’s logo and name). So certainly worth considering moving them to seperate Google account.
What if the account owner leaves your organisation?
Recently at work the first Android developer left for greener pastures. I mention first because he was only one in the Android team and registered his work Google account as the Google Play Developer owner which I’m sure happens a lot. When he left the company a few weeks ago his Google account was deactivated as you’d expect. However, because that account was the owner on Google Play we *lost* all access to Google Play console 😱😱😱. Thankfully we were able to restore their Google account which restored our access. But keeping an ex-employee’s account active just for this would be less than ideal.

I had a great time at MCE conference in Warsaw, Poland in April. I’d recommend MCE as a mobile conference I attended both Android and iOS talks and there were all high quality. Also all the people I met were very friendly and spoke great english. I was introduced to Polish vodka and some tasty polish food. Thanks to the organisers for inviting me and I hope to attend again.
In this presentation I share a story of a recent Android app I developed where app security wasn’t prioritised and how I still provided a minimal level of security to protect the app’s users and developer reputation.
For those wondering why my t-shirt has a mantis shrimp on it? check out this awesome oatmeal comic.
Last week I attended the first Blackhat mobile security summit in London. It was a great chance for us to learn from security specialists.
I co-wrote this article to highlights some of our favourite and key takeaways.
- New Android Security Rewards Program
- State of malware on Android/mobile
- Samsung / SwiftKey Zip Traversal Hack
- SSL validation (or lack of) still one of most common app vulns
- “erase everything” = not everything?
- Windows phone 8 exploits and security faux pas
I have released a new open source library to wrap a Google Play services API called SafetyNet, which has been completely eclipsed by the recent Google IO and WWDC coverage 😉
Here’s a blog post that explains a bit about what is it and why and here’s the code on github.
I’ve also released the Sample app on the Google Play store so you can run the Safety Net test on your own device.
Here’s another post I’ve written for the Intohand.com blog that lists a bunch of developer utility apps I find really useful to design, develop and validate/test Android apps.
And here’s part 2
Another blog on the Intohand blog, this time “How to publish your open source library to Maven central”
Have you created a great (or at least useful) Java/Android open source project that you want to enable other developers use in their projects easily? have you wondered how to publish your library to Maven central? then this is the article for you!
This is an extract for a blog post I wrote for intohand. Read the full article here.
Whilst emulators provide a function, nothing beats testing on real hardware. As a developer however unless you’re near a test wall of phones, have a very large bag or lots of colleagues/friends who are all running different software versions it can be a pain. It would be ideal if you could have a single phone that acted as a Swiss Army knife.
At the end of this article using a tool called MultiRom you’ll have a Nexus 4 with the option of booting into various versions of Android.
After last nights SWUX meetup I figured I’d share some more links on Google’s Material design that I’ve found since the last meetup I attended.
- An exploration in Material Design by Arthur Bodolec @ Feed.ly – good information about the Z order and a nicely polished example.
- We Are Living In A Material World And I Am A Material Girl – Trello – Great article that shows before and after material, and most interesting thing for me was how Trello got rid of the navigation drawer.
- Instagram with Material Design concept by Miroslaw Stanek – some great code samples.
Examples of Material apps – there are several of these kind of sights two of the best are:
- pttrns.com – has a new beta section showing material/lollipop Android apps. What’s great is you can filter by the type of screen you’re looking for.
- materialup – showcases material apps and websites but also material concepts and animations
- Material Palette, pick two of the material colours and this site will generate palette of 8 colours ready to drop in to your app/project
- Keyline Pushing – Android app – when running draws an keyline grid on top of apps, useful for designer/developers to validate an app is ahearence to material’s metrics and keyline spec
Yesterday, I spend a morning trying to figure out why a APK expansion file wasn’t downloading see screenshot. This problem was specifically with and Android app/game created in the corona SDK but I guess could happen to standard Android apps. After reviewing Corona labs docs are here and various forum posts it turned out to be a simple fix.
The expansion file had not successfully uploaded!! 🙁
So triple check the expansion uploaded ok in the Google Play console! We had it fail 3 times for 2 different versions without any error messages.
Check the APK file details you should see the file size includes the expansion file size and see the filename of expansion file.
