Unity3D Android plugins and SIGSEGV

Question

Hi all,

I am developing a Unity project that uses UTNotifications and a custom plugin.

Whenever I introduced the custom plugin is when the problem of these signal 11 SIGSEGV crashes started happening.

There is a button in the game that when pressed takes the user to an authorisation site in the device browser and then returns them to the app afterwards. The custom plugin is designed to let us pass back an authorisation code for use in OAuth 2.0. From print statements I can see that the code is executing to a point and then will crash.

I know that this plugin works in another game we created in which UTNotifications is not present, however it does not work on this new game and I wonder if it is a plugin conflict with UTNotifications. Perhaps it is something to do with the manifest files I have?

Does anybody know what my issue may be? I'd appreciate any help!

I've pasted my manifests and the error logs below.
