The default address of the android simulator is 10.0.2.3, and the default DNS is 10.0.2.3, which is not in the same network segment as the IP address of the computer. Therefore, the computer can access the Internet, but the simulator cannot access the Internet. In fact, it is easy to set the default DNS of the simulator to the DNS address of the computer.
Step 1: Use System commands to enter the android Development Kit tools directory
Cd x: \... \ Android-SDK-Windows \ Tool
Article 2: Use the shell of ADB to confirm the attributes of the system.
ADB Shell
Getprop
Getprop lists the current attributes of the system.
Step 3: Obtain the DNS address of the simulator.
In the result, we can see:
[Net. dns1]: [10.0.2.3]
Step 4: Change DNS to our own DNS
Setprop net. dns1
192.168.1.1
Note: If you are not sure about DNS, use the ipcnofig/all command to confirm.
These steps are generally used to set up, but I have been tossing for a day and still cannot access the Internet. In the end, I found that my environment was very strange. The simulator's DNS had to be set to a computer's backup DNS, to access the internet! I don't know. It's clear that Windows doesn't use a backup DNS either.
Note: General TP-LINK and D-LINK DNS are 192.168.1.1, if not please use ipcnofig/all command to confirm.
