Hi @simbelmine,

The current codebase probably doesn't support SDK 26, as some permissions may have been changed. The last API version I tried was 25. If you don't need features in 26, I would recommend downgrading the target.
Otherwise, if you want to send a fix that works with the newer permission models, I would be happy to review it. The fix should probably be applying the suggestion in the error message. I would do it myself, but I've been pretty packed lately.
