Figure 1
2. The problem encountered now is that in the Android App, call the interface to obtain the list data, a single data item in the list, it will appear and disappear for a while. Therefore, it is decided to determine whether the interface response data is changing by means of packet capture. as shown in Figure 2

5. Set up a mobile phone agent. The mobile phone needs to be in the same local area network as the computer, so run it as an administrator on the computer through cmd, and execute the command ipcofig to view the IPv4 address. as shown in Figure 5

6. Turn on the WIFI that the mobile phone is connecting to, and modify the network settings. Agent: None, modified to Agent: Manual. The host name is the IPv4 address that has just been viewed on the computer terminal, and the port is 8888, click Save. as shown in Figure 6

You can download the FiddlerRoot certificate
8. Right-click the file: fiddlerRoot.cer, install the certificate. as shown in Figure 8
