Test APK exception control nettraffic attacker development

1. Purpose

be based on 《 Application experience standard of software Green Alliance 》 in NetTraffic The definition of resources , Yes NetTraffic Simulation of the behavior of multiple small traffic packets in the background . Designed to trigger abnormal power consumption control mechanism in mobile phones .

Screen is off this time NetTraffic At least two levels used more than :30 Time ,60 Time , Execute the following judgment ：
The green line does not control the standard ： Important perceptible scenarios , Not limited to and including the system application white list 、 Third party application whitelist 、CTS、 Charge 、 Default input method 、 Default clock 、 Audio scene 、 Step counting scenario
The red line should control the standard ： The number of small traffic times of non downloading and uploading this time has exceeded 30 Time , exceed 5 Minutes of non perceptible scenes
Be careful ： For small packets , Avoid downloading behavior scenarios , Prevent misjudgment
The first level ： Notification alerts or power consumption tagging
The second level ： Restrict or intercept

2. testing procedure

H Mobile phones and T mobile phone 、 Other mobile phones for installation apk.
All mobile phones need to set the app to white list .

2.1 Mobile phone white list setting method ：

Cell phone manager -> Apply startup settings ： Allow self starting 、 Allow association to start 、 Allow background startup

2.2 Test environment

Turn on the Internet

2.3 Run this apk

Packet usage behavior detection in the background of screen out

2.4 Run this apk

test ： After adding white list , Run this apk after , Press home key , Off screen ,30 Minutes later, the screen will be lit to view , Whether there is an abnormal reminder of high power consumption

3. apk Source code

Ben apk effect ： Unlimited backstage WiFi Scanning behavior
