无法从 Android Emulator 访问 localhost，但在 Simulator 上它正在工作

Question

Hope anyone can help.

Why I can't access localhost (10.0.2.2) from Android Emulator, but when accessing from Simulator it's working.

I was try to edit server configuration as noticed from many tutorials, but still not working.

Here the screenshots.

Answer 1

Use a port number along with IP

http:// 10.0.2.2:8080

Works perfect !

or

you can use IP of your pc which you can get by typing ifconfig in terminal. Something like

http://192.168.1.2

Answer 2

I have found the solution for my problem.

I try to change the port, so it working fine.

adb reverse tcp:8000 tcp:8000

And now I can access my computer localhost on Android with accessing localhost:8000.

Answer 3

I just got the same problem and the reason of why I could not connect to my machine was the setting of the emulator.

How to solve:

1. Open emulator.
2. Find the button with 3 dots, press it.
3. Go to "Settings" menu.
4. Disable "Use Android studio HTTP proxy settings".
