Measure data roaming traffic on Android?
Just back from a very nice vacation in Iceland, and await the data roaming bill from my phone company. I hope for the best having limited my traffic as much as possible, but I want to know in advance. I used the very nice app NetCounter but it didn't measure roaming data traffic at all.
So I want to build my own app measuring just roaming data traffic. I have a few booleans to start with ( NetworkInfo.IsRoaming() & TelephonyManager.isNetworkRoaming() ), but I'm not sure how to measure the traffic if true.
So the question is: How do I measure data traffic while roaming? (Something like API level 8 TrafficStats functionality is what I'm after, but for API level 3). The used SmartPhone is Samsung Galaxy i7500 (Android 1.6)
Thanx for your time!

Method 1. Parse "/proc/net/dev".
In my phone it looks like:
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
lo: 712 8 0 0 0 0 0 0 712 8 0 0 0 0 0 0
dummy0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
rmnet0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
rmnet1: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
rmnet2: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
wlan0: 146112 423 32 0 0 0 0 0 42460 409 0 0 0 0 0 0
In my phone the "rmnet0" row is the one that holds the stats for mobile line internet. I hope its format does not vary among kernel versions.
Method 2: Parse "/sys/class/net".
I guess this is the recommended method. As shown here: http://www.jaqpot.net/svn/android/netcounter/trunk/src/net/jaqpot/netcounter/service/SysClassNet.java
