I saw Android has NetworkStats.Bucket class from which we can query the network data usage of an app. getRxBytes() and getRxPackets() return the number of bytes and packets received.
I'm curious is there any delay when updating the data usage?
Besides, I'm curious is there any relation between getRxBytes() and getRxPackets()? Does the number of bytes received include the header of packets(Ethernet, IP, TCP/UDP) or it only include the data attached with each packet?
Does anyone has any idea?
