NetTrafficStats

This is a free simple application for network traffic monitoring and statistics for Android devices. It is based on the kernel traffic statistics per interface such as, /sys/class/net/ppp0/statistics/rx/tx_bytes, and also on the TrafficStats class from Android.
The application consists of a background service that queries and store data as csv files after each device power cycle under '/sdcard/trafficstats/.csv' . It also comes with a basic UI for controlling the service query and save periods (1min or 1 hour).
All reported values are in aggregated sum of Rx/Tx bytes per application. Reported values seem to be more realistic than those reported by Android's 'Data usage'.
For those whom have 'busybox' with 'wget' applet can try to download a small file as shown below. NetTrafficStats should show a new entry with package set to 'null' but the bytes Sent/Received accurately reflects more the downloaded file size.
