How do I disable the Internet connection in Android Emulator?

Solved android android-emulator internet-connection

I am trying to check Internet connectivity on Android using the following method. I have a Wi-Fi connection.

private boolean checkInternetConnection() {
    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

    // Test for connection
    if (cm.getActiveNetworkInfo() != null
            && cm.getActiveNetworkInfo().isAvailable()
            && cm.getActiveNetworkInfo().isConnected()) {
        return true;
    }
    else {
        // No conection
        return false;
    }
}

I disconnect my PC from the Internet and then try to run the above method. Still it always returns true!? Why?

try this thing on device not on emulator, it will return always uncertain results on emulator on this things...!! – Stakhanovism 14/12, 2011 at 5:24

but i have to show the results on the emulator.. Is there any way i can show the results on emulator ? – Cocytus 14/12, 2011 at 5:26

Using the Pixel_3a_API_30_x86 and Android 11 in the emulator, this seems pretty much impossible. Wifi turns on again when turned off and airplaine mode makes no difference. What I ended up resorting to was changing URLs or disabling internet connection on my computer. – Filbert 15/12, 2020 at 8:57

From Eclipse

To disable the Internet connection, go to Eclipse and do

menu Window -> Show view -> Other -> Android -> Devices

Now select your running emulator and again go to:

menu Window -> Show View -> Other -> Android -> Emulator Control

Now in that... set Data to Unregister from Home.

From Device and Emulator

On the device or in the emulator, go to:

Setting -> Wireless & networks -> Airplane Mode -> OK

@user370305 yes ofcaurse..that's from the emulator and device.. okay let me add that too in the answer. – Sera 14/12, 2011 at 5:51

Ok... I tried all possible options. isAvailable in code returns false. Yet when my service attempts to connect to remote site, it still succeeds and completes the download. Possibly a bug in the emulator? – Server 8/2, 2013 at 15:42

For me the From Device and Emulator option also prevented Android Studio studio from being able to connect to the emulator, so wasn't all that great for debugging! – Spitsbergen 3/5, 2014 at 12:52

Annoyingly, it is still true that setting a Google Android emulator to Airplane mode prevents debuggers running on the PC from connecting to the emulated device! (In my case, Xamarin Studio is the IDE) – Alsworth 2/12, 2016 at 20:11

That simulates having no connection to a network, but it's also possible to be connected to a network that has no internet access. – Anonymous 6/11, 2017 at 21:53

it's funny: if you turn off wifi on the emulator and you set the emulator's "data" option to "unregistered" (or Denied) and "signal strength" to "None", the app still gets connectivity! /amazing-internet-magic – Unlive 13/11, 2018 at 10:39

even in airplane mode, wifi is still enabled and the device still has internet connection – Belabor 3/8, 2021 at 16:57

Yeah agreed I'm working on error checking for my app and I cannot hit any breakpoints while the device does not have an internet connection. Really frustrating if you just want to follow. It would be much better if you can debug while the emulator does not have an active internet connection to test these scenarios. – Keppel 29/1, 2022 at 13:57

Try the below command

WIFI:
$ adb shell svc wifi enable
$ adb shell svc wifi disable
MOBILE DATA:
$ adb shell svc data enable
$ adb shell svc data disable

Turning on and off wifi and mobile data is not the same thing. Sometimes you want to test wifi being on (and maybe connected) but no internet connection. – Anonymous 17/8, 2018 at 0:35

Does not work for me in latest version of Android Studio. After executing adb shell svc wifi disable, wifi is still enabled. – Belabor 3/8, 2021 at 16:52

You can disable the Internet connection by pressing F8 in any Android emulator. It is a toggle button, so if it doesn't have Internet connection then it will start the Internet connection and if it already has an Internet connection then it will dis-connect it.

Salinasalinas answered 22/1, 2014 at 9:52 Comment(2)

this doesn't allow me to debug anymore - eclipse launches a new emulatr after pressing f8 (even after pressing it twice). This is also the case with other methods like airplane off – Sensate 3/12, 2014 at 8:16

it is not working in my case. I am using android studio 3.3 – Porcelain 3/4, 2019 at 13:10

Android Studio 3.0 Update

Simply drag and open the control center and click on the airplane mode button as what you are doing on your actual device.

Please bear with me for a very slow emulator.

smarter way, works in windows and mac both emulators – Hannie 22/2, 2018 at 9:25

I need to have a short key for that. Any idea? – Airglow 30/5, 2018 at 6:16

I put it on Airplane mode, and stills getting internet connection. – Holmberg 21/6, 2021 at 12:37

I am still getting internet connection, even in airplane mode, because wifi is still enabled and I can't find any way to disable it – Belabor 3/8, 2021 at 16:56

It disconects from Metro server also. – Quinque 29/11, 2022 at 15:16

There are many methods. I am explaining two methods here.

Just hit the F8 key to enable or disable the Internet connection.
Just start your emulator, hold on the power button and then select:

Airplane mode Off

It will disconnect your emulator from the Internet. If you want to connect again, just hold on the power button again and select:

Airplane Mode ON

And your emulator's Internet connection will start working!

even in airplane mode, it can still connect to wifi, so internet is still enabled. also, F8 does nothing for me – Belabor 3/8, 2021 at 16:56

To check on a real device (and also in the emulator), go to:

Settings > Wireless and Networks > Mobile Networks > Data enabled

Uncheck it and it will work.

this only disables mobile data, not wifi – Belabor 3/8, 2021 at 16:55

Recent emulator versions provide an easier way, from an ADT view:

Window -> Show view -> Other... -> Android -> Emulator Control

Simply change "Data" value from "Telephony Status" and test your application again.

Backache answered 29/8, 2013 at 12:24 Comment(1)

this may have worked back in the days of ADT, but ADT is no longer supported and this doesn't work for me – Belabor 3/8, 2021 at 16:55

You can actually disable internet connection in the simulator just as you would in a real phone.

Swipe down the screen to see the notification panel.
Tap on the data network icon
Turn off the cellular network.

I just tried it successfully in an android 4.4 image loaded into my simulator.

None of the other answers to this question worked for me, the only thing that worked was

adb shell -> su -> ifconfig wlan0 down

and you can use ifconfig wlan0 up to bring it back up again. (I had to restart the device, even after executing ifconfig wlan0 up.)

Obviously make sure mobile data is disabled (or device is in flight mode) before trying this.

Thanks a lot to noamtm's answer for the hint!

Steps to disable Internet in the Android emulator:

First install the application into the emulator
Long press the power button of your emulator
Choose Airplane Mode

Now your emulator won't accept an Internet connection.

Note: Here after Airplan mode, you can't install and run your app in the emulator, so before putint it into Airplane mode, run your app in your emulator.

For changing to normal once again, long press emulator and choose the same option.

the device can still connect to wifi, even in airplane mode – Belabor 3/8, 2021 at 16:53

telnet localhost 5554 (or Android emulator number)

Internet enabled:

gsm data home

Internet disabled:

gsm data unregistered

You can use my library, available on http://www.cristianmarquez.com.ar.

Baculiform answered 31/10, 2013 at 13:38 Comment(2)

The emulator reacts to the command moving gsm status from 'local network' to 'no network available' but the internet connection from the emulator remains the same. – Tumid 22/10, 2015 at 14:59

My app was built using React Native and what worked for me was running the device in debug mode and disabling the network connection from the throttling dropdown menu within chrome devtools.

Note: this flow disables any XHR calls made directly within the app code. Any requests done through embedded portals/views might still work if the code generating those requests are outside the app's source directory/code.

I used the React Native Debugger standalone app for this and I followed these steps:

Select the terminal running react-native start and open the developer menu by pressing the letter d

On the emulator, select Debug from the developer menu

Open the React Native Debugger standalone app
On the emulator, close out and relaunch the app to connect with the React Native Debugger. If using non default local dev port/connection values update settings within the React Native Debugger app.
Enable network inspect on the React Native Debugger app by right clicking on the React or Redux devtools windows
Navigate to the Network tab on the chrome devtools window within the React Native Debugger app and disable the network connection from the throttling menu
