Exchange crashed, backups failed, only mail is on my mobile (andriod) device, is it possible to move that data to Exchange Online?

Bad weekend... I had a piece of hardware fail which spiked the power and took out my UPS which dropped my SAN and subsequently killed my Exchange 2010 server. Then I found out that the Veeam backups I had been doing were not backing up exchange properly. I was already planning on migrating to Exchange Online in another month but this kind of puts a little more priority on it.

During this process I discovered that my workstation's outlook was not caching my emails/contacts/calendar to a local PST. However, my Android has at least the most recent 2 weeks of email and all of my calendar appointments.

I just got Exchange Online setup, is it possible to feed what is on my Android device back up to Exchange Online?

That's doubtful unless you can somehow export the email from your phone.

What you can do if you have access to the Exchange mailbox database (EDB file) is use a third party utility to export the mailbox contents, which can then be imported into your Exchange Online mailbox.
