I’m developing an Android app which needs to download a lot of data.
To improve the usability, I’d like to measure the data traffic my app produces and give the users a hint if the app downloaded a specific amount of data.
My current idea: Sum all downloaded bytes together and react on a specified limit. However, as I downloaded things in many different situations and in many different positions in the code, is there any other possibility to measure the data usage per app?
sys/net/NETINTERFACE/statistics/rx_bytes reports the total amount of the whole system, so this is not a solution.

TrafficStats may be able to report things by UID. I say “may” because it seems tied to devices. I suspect that Android 3.0+ will consistently report by UID, but my 2.2 and 2.3 experience has been mixed.
Here is a sample application demonstrating recording this information.
