The same code works fine all sample apps, but in our app a native crash occurs and it's really hard for us to figure out what's wrong. Unfortunately, I cannot share our product app. It doesn't matter whether I use the terminal or Android Studio to build the app. The crash happens in the emulator and on real devices.\r\n\r\nI'm using Flutter beta 2. I've tried to remove all other native libraries we, but the issue remains. I have no idea anymore what could be different to other sample apps with the same code and same project setup.\r\n\r\nThis is a backtrace from an API 23 emulator:\r\n```\r\n04-10 18:42:15.066 1712-1712/?
