While doing mobile development there is always a need to present or capture your screen (for bug description) with an application actively running on the screen. Here are my tips and apps I use often that help me to achive that goal for both platforms. I hope you will also find them useful.
iOS While using iOS devices, both features are already build into the system.
To present mobile screen on desktop:

And there is one recipe I tend to forget quite often, which I also found extremely useful, while writing tests exercising (or relying onto) any external data.
In this scenario, all the content is kept outside of the unit-test itself and is simply read at runtime from resources (aka assets).

Press Settings on the remote and navigate to Settings > All settings > Android Settings.
Open System Information.
Click 7 times on Compilation version.
This should enable “Developer Options”. We just crossed half of the way.

Let’s also try to have some C++ code around, that is shared with other platforms and that interacts and configures OpenCV video processing. Of course nobody expects any rough edges nor problems, right…
One might think it’s a typical scenario and lots of mobile apps use OpenCV this way.

At first glance the OS was OK, Android SDK was also OK, but then fastlane installation was not happy about something. And that little something turned out to be a real PAIN … in my arm! Ruby ta-da-da-tam! But how was that?

Unfortunately might lead to a clash, since only one virtualization technology could be used at a time. And if you continue using Docker for Windows or any other Hyper-V based virtual machine with Linux system, something will not work (depending, what was launched first).
Fortunately Microsoft solved this problem with 1803 release for Windows 10.
