Android simulators use local computers to access the Internet

After entering ADB Shell

Ping 127.0.0.1 (Android address) can be pinged

Ping 10.0.2.2 (Local Computer address) or ping

However

Ping www.baidu.com or other Internet services means Ping fails.

Solution!

In Windows, After configuring the adroid environment variable (such as adding D: android-sdk-windows-1.0_r1 ools to the system variable path), enter in the command line window:

Emulator

After the android simulator is started, enter:

ADB Shell

Enter the ADB shell mode:

Write the network connection proxy settings to the configuration database. If your Internet proxy IP address is 10.193.xx.xx:

Sqlite3/data/COM. android. providers. settings/databases/settings. DB "insert into system values (99, 'HTTP _ proxy', '10. 193. XX. XX: 1080 ')"

Check whether the system settings have been successfully changed:

Sqlite3/data/COM. Android. providers. Settings/databases/settings. DB "select * from System"

The result should contain 99 | http_proxy | 10.193.xx.xx: 1080.

Restart the simulator and use the Internet on browser.

How to delete the configuration information just written:

Sqlite3/data/com. android. providers. settings/databases/settings. db "delete from system where _ id = 99"

The default address of the android simulator is 10.0.2.3, and the default dns is 10.0.2.3. For people who study android online at home (like me), the ip address of the computer is 192.168.1.100, not in the same CIDR block. 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 ool

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]

[Net. dns2]: [10.0.2.4]

[Net. dns3]: [10.0.2.5]

[Net. dns4]: [10.0.2.6]

Step 4: Change dns to our own dns

Setprop net. dns1 192.168.1.1

Note: Generally, the dns of tp-link and d-link are 192.168.1.1. If not, use the ipcnofig/all command to confirm.

If you use the browser of the simulator again, you will find that you can access the Internet.
