Android devices can connect to the internet via Wifi or GSM if they have 
a SIM.

As for running your own code on it. Quite a few people write their own 
apps. (Sorry programme is too big a word to use.)
For instance the battery monitoring app I have will record, store and 
graph the battery voltage. It can access the tablets internal inputs, 
temperature, phone signal strength, accelerometer etc. It can output a 
text file for debugging.

Does this help?
TL;DR

Raspberry jam, indeed. ;-)
