The mac platform uses adb and tcpdump tools to capture the network package of android phones and tcpdumpandroid

When developing a mobile app, we want to check the network requests sent by our app. In this case, we need tcpdump to capture packets. To implement tcpdump, you need to take the following steps:

The following uses the android mobile phone Huawei P6 as an example.

1. Mobile phone ROOT

To use the tcpdump tool, you must first obtain the root permission of the mobile phone, try several root tools, and finally find that the 360 one-click ROOT tool can root the P6 Machine

Download the 360 one-click root tool for PC, connect the mobile phone to the computer with a USB cable, and enable USB debugging (Settings> developer Options> USB debugging)

Then, follow the prompts to run the ROOT command.

2. Download the adb Tool

At the beginning, I downloaded the adb of the earlier version from the Internet, but it never succeeded and showed offline. At this time, you have to download the adb of the latest version.

One way is to download an ADT from the developer android http://developer.android.com/sdk/index.html, there is the latest adb

The other is to download the latest 1.0.31, Which is uploaded by adb,

3. After downloading the adb, you can test its version and run the cd command to its directory.

4. Then,Unauthorized is found when you use the adb devices command. In this case, you need to disable the developer option of the mobile phone before enabling it, and then obtain authorization.

If you get authorization, your computer will be in ~ /. Copy the key in the android directory to the mobile phone.

Then copy the downloaded tcpdump to a directory on the mobile phone.

Then log on with the adb shell. After logging on, use the su command to switch to the root user, go to the tcpdump directory, and add the executable permissions of tcpdump (use chmod 777 tcpdump)

6. Use tcpdump,Open your app and you will be able to see its packet capture information.
