Exchange calendar syncs to Android, but not to Google I feel as though I am missing a simple configuration change on my Android device.  I recently setup my work Exchange account on my Galaxy S4.  My calendar entries from Exchange show up on my Android calendar just fine.  However, I want those entries to actually get pushed to my Google calendar.

Is there an easy way to have my Android device push those events to my Google calendar instead of keeping them local to the phone calendar itself?
Share the ICS URL of your Exchange to Google Calendar.

From an Oregon State University HOWTO:


Click on Calendar in the lower left corner
You should see all your calendars in front of you. On the left side of the window, you should see the list of calendars and their names. Under My Calendars, right click the one you wish to add to your Google account.
After right clicking your chosen calendar, right click, go Share &gt; Publish This Calendar (Publish This Calendar to the Internet)
A new window will pop up. Select the options for which best suit you. 
When complete, press Start Publishing in the lower right corner.
A couple of urls will show up for you to copy. Find the one that ends in .ics and copy that whole url.
Go to Google Calendar
When logged in to view your calendar, go find Other Calendars on the left side of the window
After finding Other Calendars, there should be a box with a triangle in it to the right of the text. Click that box and find Add by URL.
A popup will show up. In this popup, you want insert the .ics URL from your Outlook here.
Press Add Calendar below.
