Solution 1:^[1]

What I did was to get the data from this files

/sys/class/net/< interface>/statistics/tx_bytes

/sys/class/net/< interface>/statistics/tr_bytes

then I saved the values using sharedpreference y made some code also for getting just the new values and add it to the saved values.

I made a lot of research but queryDetailsForUid using UID_TETHERING never worked

the interfaces are wlan and wwan
