I am concerned what the System warning in my android app means.
ch.ethz.inf.vs.a4.minker.einz W/System: ClassLoader referenced unknown path: /data/app/ch.ethz.inf.vs.a4.minker.einz-1/lib/arm64
This warning comes up when I run the app and then don't do anything - just displaying the main Activity. The app does not crash, but I'd like to know why these warnings are showing up.
This is the complete logcat when I run the application on my Sony Xperia device, but the Emulator creates similar logs.

This answer mentioned disabling instantRun, which I have already done because of my version of IntelliJ not supporting the latest version of gradle yet (last time I checked with support). It also mentions WiFi, but that doesn't seem to make a difference.
This answer mentions clearing app cache and data, but this also does not make a difference.
It might be worth mentioning that the first time I run the app, IntelliJ shows the following error in the logcat. This happens both on the emulator and my real device. With "the first time", I mean that it does not show the error when I click run again and select "restart app". This behaviour is not 100% consistent though.

What could be reasons for these warnings? I am afraid that if I ignore them, I will at some point spend days debugging only to find out that these warnings would have told me.
