How do you connect localhost in the Android emulator?

Question

I have made a php script inside localhost and I am connecting that with httpClient but I am getting a problem.

Please tell me how can I connect to a php file at localhost from the emulator?

Use `10.0.2.2` to access your actual machine.

As you've learned, when you use the emulator, localhost (127.0.0.1) refers to the device's own loopback service, not the one on your machine as you may expect.

You can use 10.0.2.2 to access your actual machine, it is an alias set up to help in development.

Nice though this isn't useful for e.g. oauth though where a clientID is only valid for `localhost` – Dominic Jul 27 '17 at 15:14

10.0.2.2 not working for me in case of https localhost, do i have to use different ip in case of https? – Manu Nov 15 '18 at 07:15

But you need to change API from "localhost:port" to "127.0.0.1:port" first. after that, Use 10.0.2.2 to access your actual machine. – binhtruong.it Dec 09 '18 at 11:49
Is there any possibility to use siteurl/siteHost instead of ip, i can not use ip? – Meenakshi Khandelwal Apr 22 '20 at 16:09

This is probably the best solution and it doesn't require proxy configuration on AVD (https://stackoverflow.com/a/59217370/6422750 actually doesn't either). You can access your endpoints defined on the server via `http://10.0.2.2:/`. – Theta Nov 27 '20 at 12:26
what in case when one wants to access the localhost along with the subdomain? – Vivek Mahajan Apr 17 '21 at 05:54

Use 10.0.2.2 for default AVD and 10.0.3.2 for Genymotion

Thanks, @lampShaded for your answer.

In your API/URL directly use http://10.0.2.2:[your port]/ and under emulator setting add the proxy address as 10.0.2.2 with the port number. For more, you can visit: https://developer.android.com/studio/run/emulator-networking.html

This is what finally worked for me.

Backend running on localhost:8080
Fetch your IP address (ipconfig on Windows)

Configure your Android emulator's proxy to use your IP address as host name and the port your backend is running on as port (in my case: 192.168.1.86:8080
Have your Android app send requests to the same URL (192.168.1.86:8080) (sending requests to localhost, and http://10.0.2.2 did not work for me)

This works for me too but I believe proxy is not necessary - logs on my Flask server showed that when proxy was configured, AVD generated plenty of weird and unnecessary GETs and CONNECTs that resulted in 404s. Switching back to `Use Android Studio HTTP proxy settings` fixed it and now the server receives only valid requests that I explicitly want. One more thing you could do for your convenience is assign a static IP address to your machine, for instance via your router settings so that DHCP won't be able to change it. – Theta Nov 27 '20 at 12:12

Defining network security config in xml

<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
       <domain includeSubdomains="true">10.0.2.2</domain>
    </domain-config>
</network-security-config>

And setting it on AndroidManifest.xml

 <application
    android:networkSecurityConfig="@xml/network_security_config"
</application>

Solved issue for me!

you should change the adb port with this command:

adb reverse tcp:8880 tcp:8880; adb reverse tcp:8081 tcp:8081; adb reverse tcp:8881 tcp:8881
