This part seems to be interesting: Java.Lang.NoSuchMethodError: no method with name='getDrawable' signature='(I)Landroid/graphics/drawable/Drawable;

getDrawable was added in API 21, this means that you shouldn't be calling it, rather you should be calling ContextCompat.getDrawable(Context context, int id)

Despite the exception happening on SetContentView line with none of my code in the stack trace the issue was caused by a custom view which was used by my main view. Which was not using the ContextCompat version of getDrawable
