Yeah, the same thing is happening with me to. Just this morning had a CL match I couldn't attend. Top 11 wasn't even running since last night. Opened google music on my phone and a minute later, load up my data connection and immediately got the "Top 11 has stopped working" message. My CL match was supposed to have ended like 15 or so minutes prior, so this means that the game tried to send me a notification about the end of the match.

Doesn't directly harm the game or the player to be honest though. Realistically it only happens when you get a touch notification from the game and if you're currently playing, well, you won't get any of those. So the game won't actually crash while you're playing is what I mean.

Also yay. messenger crashes all the time due to this. Cheers! >.>

But anyway. No fix for this atm it seems. Will have to wait for Android to be updated.
