Android BeagleBone Black

[Google Code Exporter]

What steps will reproduce the problem?
1. I installed SerialAPI_1.1.apk on my Beagle Bone Black running Texas 
Instruments Android 4.2.2 image
2. The apk installed normally...
3. When I run the program and try to do anything that accesses serial, I get 
"Error: You do not have read/write permission to the serial port."
4. How do I get permission?
5. I have tried to do the things listed at the following 2 links
  a. http://beaglebone.cameon.net/home/serial-ports-uart
  b. http://stackoverflow.com/questions/19683336/root-permission-to-configure-uart1-in-beaglebone
  c. I cannot install any text editor because I once again, do not have permission, so I cannot follow the steps from b above...

I think the problem is that I don't have root. Is there a way to get that on 
this image/device combo?
