"inbyggt bibliotek stöds inte på den här enheten"

[zakerymcc]

OS: Android 5.1
Hardware: Google Nexus 5
Standard vanilla Android on standard Google device. No other funny apps, rooting, or the like.

While I was nexting through bases in multi-player mode a message appeared on the screen that said:

"inbyggt bibliotek stöds inte på den här enheten"

The message is in Swedish (which I happen to know), although I am in the US and only have apps and language settings in English.

Normally I would have thought that was a system message, but I'm 99.9999% sure it came from COC because it is the only application on my phone that was programmed in Europe, let alone a country where Swedish might be used in error messages. Not to forget the fact that it happened while I was using the COC application...

Supercell, please advice.
