Android vs. iPhone. The State of Mobile App Quality

uTest published a really nice Infographic about the State of Mobile App Quality comparing Android and iPhone. The graphic compares the user happiness and the complaints. In total 77,136 Android Apps and 62,093 iPhone Apps are considered for this infographic. Take a look at it, it really interesting!  

Useful Android Development/ Testing Tools powered by troido

This week I attended the Mobile Developer Conference in Hamburg/ Germany. In the talk from Miroslav Simudvarac (www.troido.de) he presented some really useful Android Development Tools. I really like the tools and I think they are really helpful for Android Developers or Quality Assurance Experts.

The first tool is the so called re-signer developed by Miroslav Simudvarac. If you want to test e.g. with Robotium against an existing APK file and you don’t have access to the source code, you need to resign the APK file with your own signature. In a previous post I explained why you have to change the signature and how to do this on a commandline. With the re-signer tool you are now able to resign APK files over a graphical user interface. All you need ist the re-sign.jar file and an installed Android SDK. The tool can be downloaded from here. Download the jar file and execute it with a double click or from commandline with java -jar re-sign.jar. The following user interface should show up.


To resign your APK file, just Drag & Drop the file in the window. If the resigning was successful a popup window will show up and give you the information about the starting activity and the package name of the APK file that you need for your Robotium Manifest.xml file. Thats it! Now you should be able to resign APK files even faster!

The second tool is the so called Cert-Checker.

Android Testing Service – Apkudo

If you develop your Android app(s) in a small team without a dedicated QA guy or in a one man show, you have to test the app on your own. Usually developers test the app in the Android simulator with different Android versions and at least on one real device. The fact that Android is available in hundreds of custom configurations on over 200 different devices makes testing a real challenge for small teams. To ensure that your app runs on every device, you would have to buy a lot of hardware and need a lot of space to store all the devices. This waste to much time and is also very expensive.

But this could change now!
