why does the app crash in device but runs in emulator?

I uninstalled and installed the app on my device and it started to crash.
Here is the logcat

Reminders app tutorial, app does not load, issue with java file

I am learning Android Studio from a book called "Learn Android Studio: Build Android Apps Quickly and Effectively" By: Clifton Craig; Adam Gerber. I am following a tutorial on how to build a Reminders app and can't get the app to load. In the tutorial, I have been instructed to alter the onCreate() method with what is provided in the book, making sure to import what they provided.
The altered code is provided here.
The logcat is provided below:

Based on the stacktrace and based on another crash we were having, i believe it may be something to do with MultiDex being enabled. The crashes were only appearing on Android 4. devices. However, if someone could just clarify it for me that would be great.
Just in case. Another issue that has been occuring is this one. Not sure if there linked as its happening on android 5 devices.

Sorry about the wall of text. I'm not sure what the problem is here, maybe someone can sort it out here?

Create a new project in Android studio and copy everything from the old project into the new one.
