There are many techniques for analyzing images for mobile apps. Lot of solution offer many different features, and finding solution which perfectly match your needs may be difficult task. For one of our internal project, we need to analyse image for getting information about shapes (like rectangles, triangles and so on) which match our requirements. To do it, we had to check some popular solutions for images processing. Our solution had to be compatible with both Android and iOS platform, because we did not want to implement our algorithm twice, and we would like to have exactly the same result on both platforms. You can see results of our research here:

VR Technologies for Mobile Apps

This is the second part of our story and research how to create a VR app. The first one, here, was about linking OpenCV, which we need for a certain reason, and creating a framework with shared code. Now, let's move straight to the VR. The very first question was "how to create and show 3D and/or VR world in a native app?". If you are a game developer, then it may sound silly. We are not, but we had a knowledge about a few solutions, so we took a deeper look at them.

 If you’re a parent, maybe you’d find it convenient to be able to know if everything is alright with your baby, even when you’re not in the same room. I participated in a project which had a goal to enable parents to do exactly that. We created a mobile app intended to give parents the ability to monitor their babies remotely.

This article is part of a series: Android Security Analysis Tools, part one - JAADAS Android Security Analysis Tools, part two - DIVA app and AndroBugs Android Security Analysis Tools, part three - Drozer and QARK  Android Security Analysis Tools, part four - MobSF We present last part of the series of blog posts dedicated to security analysis tools for Android apps. The tools discussed in the series were suggested by the OWASP Mobile Testing Guide (MSTG). In the previous parts we discussed JAADAS, Androbugs, Drozer and QARK. This chapter will focus on MobSF, which is also suggested by MSTG. The main goal of the overview is to find the best tool that will be also easiest to integrate with existing CI/CD stacks.

Thanks to the fact that it can run on multiple platforms, Kotlin is gaining more and more popularity in multiplatform development. Recently we have started a dedicated R&D working group in Netguru in order to establish best practices for multiplatform development and to evaluate how much code reusability we can achieve using this technology. We’ve started to work on an online, multiplayer game project consisting of a Spring backend module along with iOS and Android client apps.

Reactive libraries comparison Reactive is a huge buzzword in Android development lately. With the rise of RxJava, most of the developers are familiar with the concept. But the world moves on and now there are several tools that can make your app reactive. The new developments are LiveData and Kotlin Coroutines. Is RxJava obsolete now? Or should we stay with proven solutions? Let’s find out.

This article is part of a series: Android Security Analysis Tools, part one - JAADAS Android Security Analysis Tools, part two - DIVA app and AndroBugs Android Security Analysis Tools, part three - Drozer and QARK Android Security Analysis Tools, part four - MobSF   Welcome to the third part of the blog posts series dedicated to security analysis tools for Android apps. The series focuses on the tools suggested by the OWASP Mobile Security Testing Guide (MSTG). In the first part we discussed the problem of security analysis and looked at the JAADAS framework. The second blogpost  was dedicated to an overview of the AndroBugs framework and the DIVA app as a benchmark for security testing on Android. In this chapter, we will focus on two tools - Drozer and QARK.

In the previous post about Android Slices, we took a look at their possibilities, created our first Slice and tested it in different modes. In this article we will focus on more advanced slices which can take in-app actions and fetch data from our application. Let's take a look at Interactive and Dynamic Slices.

Android Slices are a brand new way to display remote content from your application in many different places, such as Google Search (and Google Assistant in the future). We can think of them as interactive, templated views. Thanks to standardized rules how Slices can be created, they can be used across many different Android versions. Slices are part of Android Jetpack, which makes them backwards compatible back to API 19 (KitKat) - so Slices will be available almost to all users of Android devices.
