For anyone out there that needs to pull an apk from your gnex to side load to another device, I figured out how to do it. Basically, Siruius xm just released a new apk (first one in forever) but their supported device list is very small. It works flawlessly on the gnex and I wanted to put it on my Asus Transformer running ICS. To do so, I downloaded a free app called File Expert. Then I clicked on the app tab in File Expert and checked the box next to the app that I wanted to save the apk for. It then backed up the apk to / mnt/sdcard/backup_apps. I was able to then email it to myself and open it on the other device. Now we can listen to XM on the tablet as well. This might also be a good solution for when you do not want to upgrade an app, you could save the apk file of the app you are currently using, then allow it to update. If you don't like it, you just re-install the old version. Maybe this can be done with Titanium, I tried, but was not able to figure it out. It did not show it backed up as an apk. File Expert worked great, I can think of a lot of reasons you might want to save an apk file.
