Android program traffic monitoring

TestTrafficMonitor

This is a program for testing the system traffic statistics class TrafficStats, which can be used to easily monitor APP traffic;

Summary of the use of the TrafficStats class:

1. This class provides methods directly: the number of traffic and packets used by all APPs using the mobile network, the number of traffic and packets used by all APPs, and the number of traffic and packets used by an APP;

2. The data provided by this category is accumulated by switching the mobile phone on and off, and the data will be reset to 0 after the shutdown and restart;

3. It is not possible to directly obtain the traffic statistics of an APP using the mobile network and wifi network through this category. If you need to distinguish the network type for traffic statistics, you need to open the background service, monitor the network status change broadcast, and record and record according to the network status change. Calculate traffic statistics under different network types;

4. All network traffic statistics provided by this category may not only include mobile networks and wifi networks, but may also include traffic generated by socket communication between APPs;
