Not aware of a step-by-step guide, but it shouldn't be too complex. You did get the Android adapter with the Lonelec cable? Otherwise you need a so-called OTG cable, which converts from the tiny micro-usb on the device to an USB port you can plug the Lonelec cable into.
If you don't have that, hit up Amazon and do a search for "otg cable" and you will find many, pick one that looks nice and plug that in between your Lonelec cable and your Android device.
With that, you fire up the program, plug in the cables and should get a connection. Then choose the "Read Map" command. That should get the information out of the ECU into the Android, this will take a few minutes. Stay away from the Reprogram choice for now...
Getting files into and out of an Android device is usually also a doddle - just use a normal charging cable to hook the device up to a PC. The Android device should show up as a removable drive you can just drag and drop files to/from. However, that said, looking at
http://tuneecu.com/TuneECU_En/android.html I don't see any mention of a "save to hex" function, there is an "open" function though (ie load a new map from the Android's internal storage for sending to the ECU with the Reprogram function) which you'll probably use to read in the modified map when you get it back.
I've been too cheap to actually buy the program since I don't expect I'll be tuning my bike anytime soon and already have the Windows version working just fine... so can't verify some of these assumptions I'm making.
If there is a save to hex function, use that to save it to a file on the Android device, then copy that to the PC and send it as a file from there. If there isn't, try using the copy function from the copy/paste section, then open your mail program in Android and use paste there to paste it in and see what happens. Maybe you can mail it out right from the device.
