Slow interaction with Android apps - possible solution

[odklizec]

Hi guys,

I've recently started automating Android apps and I was shocked about the speed (slowness) of interaction with instrumented apps via spy and overall speed of playback. A simple test consisting of login, few touches and validations here or there and logout took about 18-20m! Plus it was incredibly slow to interact with the app UI, via Spy. Just today, I found an old post discussing similar issue. And sure enough, disabling "Full image comparison" in instrumentation settings helped also in my case! The same test now finished in 1.8-1.9m and interaction with UI via Spy is smooth, like working with desktop/web apps. I can finally track elements, without 30s or longer delays, between clicks in mobile app UI tree

You are most likely aware of this, but when you run your tests over WiFi, not via USB it also speeds up you test execution. But anyhow, thanks for the hint. Much appreciated!

Hi Milan,

Yes, I'm aware that wifi is supposed to be faster. However, it was not helpful in this particular case. It appears that if the instrumented app features camera functionality, this instrumentation flag dramatically slows the Ranorex/AUT interaction performance.
