Network Usage is an utility which shows both 3G and wifi traffic usage since last connected. It also lists all app's network usage and sorts them based on the amount of data sent and received. This helps user to notice which app consumes most bandwidth and may need to uninstall or stop the process. It has been tested on Nexus one. Please send bug report back if you encounter any problem on your model. Any feedback is highly welcome.
Note: Some phone models do not enable uid_stat(kernel level configured by phone manufacturer), the network stat for each app might not be displayed correctly.(always 0) thus list active connections instead.
keyword: net counter, realtime traffic, traffic counter, network stat.
