Training and Developer Docs
Would you like me to speak at your conference or meetup? If so please get in contact.
Any questions, please drop me an email or tweet.
Droidcon London is one of my favourite conferences with it’s wall to wall Android theme. I’ve spoken 3 times over the past 6 years or so and I’m super excited to be speaking this year after a break of a couple of years. I tend to speak about Android Security because it’s an area of app development that isn’t often prioritised high enough. Mobile security comes with it’s own set of challenges where devices and data are physically at more risk than traditional PC/Laptop environment.
In addition to checking out the other security talks I’m keen to learn tips and quick wins for view animations and screen transitions. Also top of my list is learning from real world experiences and lessons learnt using different architectural approaches such as MVP and Clean architecture. I’m looking forward to getting to grips with Kotlin based on the news that Kotlin is supported for build scripts in Gradle 3.0.
My Talk – What’s NNNNNNew in Android Security?
As you might guess from the name is all about the new security features in the most recent versions of Android: Nougat aka N.
Who should come to it?
There were several notable security updates in Android Nougat and in this talk I’ve distilled the information specially for the busy developer who don’t have a lot of time to invest in learning new APIs. I’m personally most excited about Android 7’s Network security config. It’s an easy way to increase your app’s network security without writing any code (just xml based config). I’ll show you the most likely things you’d use it for with code samples. For example allowing self signed certificates for development API and SSL pinning.
See you there!

ConfConf as you might of guessed from the name is a conference about conferences (how meta!), specifically how to run them better! It’s a small single track conference based on professional event organisers sharing their top tips on making the best conferences.
Top 5 tips for running your first technical conference
At SWmobile (a meetup group which I co-run) we’ve talked a little about running our own conference. Here’s the top tips I picked up for others also looking to do this:
- Independent and for profit – The conference should be independent financially from any non-profit group and the aim should be to make a profit with the conference. This separation helps focus the effort required to setup and run a conference. I thought a good suggestion was to aim to run it for 3 years and if it’s not profitable after 3 years to abandon.
- Ticket price – The super secret but also simple ticket price calculator should be the total costs / total number of tickets. It’s important not to include sponsor money and so the focus of the marketing is ticket sales. Any money you get from the partners you get on board will increase the chances of it being profitable and allow you to improve things like swag, free beers etc
- One day only – One day conferences have tended to be more popular recently as it helps keep cost down and it’s easier to convince bosses for the time off to attend.
- WiFi – Get this right! don’t skimp or rely on the venue’s setup. Sure they’ll say they have a great network but remember this is a tech conference and most attendees will have multiple devices. Rule of thumb 2.7 devices per attendee. Great article from last years confconf.
- Ditch lunch – Don’t bother with lunch, catering costs allot and is generally crappy quality. This really hit home for me as I cannot think of a conference I’ve attended where the food was good. It’s also one of the main things people moan about! confconf’s lunch was fairly standard meeting food which was above average for a conference. However they did win the day by pulling out afternoon cream tea!
Top 5 tips for monthly meetups
This is geared up for monthly, free to attend meetup groups such as SWmobile. This list is geared more to the sorts of things I think we can improve on so your mileage may vary.
- Sponsors == Partners – referring to and treating sponsors as partners helps emphasise they are more than just giving money. By working together you can use their ‘reach’ to promote your events.
- Improve speaker management – Be up front about talk timings, whether costs are covered, venue directions, uniqueness of talk, number of attendees, type of audience, who to call in emergency, and in general communicating better before and after an event.
- Open a CFP – have a Call For Papers [CFP] for monthly meetups where prospective speakers can easily submit talks. Allow them to indicate if they are new to speaking as this allow you to mix up evenings with pro and newbie speakers. As with the above point and speaker management, be sure to include things on the CFP things like the typical location of meetups, average number attendees, attendee skill/experience level.
- Create Code of Conduct policy – If you already have a code of conduct like we do at SWmobile, that’s a great start. But what happens when a complaint or issue is raised? this is where a policy comes in. Be sure to ensure all organisers/volunteers are briefed on this.
- Video promo reel – Recording talks are a good way to allow people who couldn’t attend to watch the talk. They also serve as a way to promote the group. However recording and editing can be costly and time consuming. A better use of video would be a promo reel to promote the group and ideally a separate video tailored to prospective speakers, members and partners.
As in mention in my tweet above I had tons of notes and this is just a small portion of the knowledge gained. I’d definately recommend confconf.com to techincal meetup and conference organisers. Hope to attend next year! Also more tips can be found on the confconf blog.
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.

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 been fortunate enough to be invited to speak at goto; conference in Copenhagen on October 6th. I’ll be giving a talk I one of my favourite subjects: Android app security. If you can make it please come and say hi.
Global mobile adoption is spreading like wildfire, pervasive government surveillance programs are coming to light and major internet security exploits are being uncovered. This results in increased awareness from users, managers and developers for the dire need for rigorous security in deployed code. While mobile device security can be helped via mobile device management (MDM) solutions it’s our responsibility as app developers/publishers to ensure our apps protect user privacy and critical business data. The problem is securing your Android app and data is not always obvious or well documented.
This talk will cover current Android app threats and look at how with freely available tools we can easily reverse engineer an Android app. After a brief introduction to Android platform security and how to protected app components, we’ll cover enhanced SSL validation, encryption, tamper protection and advanced obfuscation techniques. We will also focus on leveraging open source commercially viable libraries allowing us to increase our app’s security with minimal effort.
These best practise techniques will arm you with practical solutions that can help you survive in the Android security jungle.
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
I created this Google slides template using the Android Holo theme a year or so ago and didn’t for some reason blog about it at the time. Please feel free to Download and use in your presentations.

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!
