I have installed a PWA on my Android device and I want to remotely debug it in Chrome on my desktop. When I connect to my device in Chrome dev tools, all I see are the tabs open in Chrome on my Android device. I do not see the instance of the PWA that has been installed - "added to homescreen" Is there any way to debug the installed instance?
You have to open your developer tools using Ctrl+Shift+I
Then go to More Tools -> Remote Devices
In Remote devices, you can see your available online device and click on that(either online device can be emulator or it can be attached mobile device), also you can Add Rule if you want to run in localhost from mobile device.
Click on Inspect button, available in right side
Now you can see virtual device is created and you can see all logs that comes from device will display in Console tab
I was having the same problem. Turns out that PWAs that were open before you connected remote debugger will not show up. Simply close the app and start it after connecting the debugger.
I have the samsung galaxy tab, when I plug it into to eclipse to run and debug my apps. Eclipse doesn't recognize the device. When I try it with my friend's Droid 2 it still doesn't work. Can someone please help me?
If you are developing with Windows, you might need to install the USB driver for our device. For Windows 7, here's how you do it:
To install the Android USB driver on Windows 7 for your device:
Connect your Android-powered device to your computer's USB port.
Right-click on Computer from your desktop or Windows Explorer, and select Manage.
Select Devices in the left pane.
Locate and expand Other device in the right pane.
Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch the Hardware Update Wizard.
Select Browse my computer for driver software and click Next.
Click Browse and locate the USB driver folder. (The Google USB Driver is located in \extras\google\usb_driver.)
Click Next to install the driver.
Check this link for more information if you need it.
Have you tried:
Settings -> Applications -> Development - Enable USB Debugging
In android 4.2.* The “Developer Options” menu item is gone!
Answer: The “Developer Options” menu item on 4.2.* is hidden.
Goto Settings -> About Phone.
Goto “Build Number” at the end of the Scroll list.
Tap on “Build Number” repeatedly (7 times). On your third tap you should see message indicating that you only have 4 more taps to go to ‘become a developer’.
Continue: 4 more taps.
Hooray, you are now a ‘Developer’, go back to the Setting page.
You should see Developer Option menu item in your setting list now.
Open Developer Options and check USB debugging > Ok
****it's work for me****

download the samsung software Kies .it detects samsung deivces
Go to http://developer.android.com/tools/device.html and follow up
this solution worked for me
In addition to Settings -> Applications -> Development - Enable USB Debugging, click on the following option:
Revoke USB debugging authorization
And then plug the device again.
Addition to Tor-Morten's answer: Only checking the Developer setting for USB debugging may not be enough. The USB connection setting (Android 4.4: Settings -> Storage -> Option Menu -> USB computer connection) needs to be checked for either "Media device" or "Camera" before it will be shown in Eclipse's Android Device Chooser window.
Maybe its a matter of how you plugged the device onto your computer. I'm using a mac and pluged the usb into one of the keyboard slots. It doesn't find anything even you've installed Kies with all its new drivers.
After plugging it directly into one of the slots at the computer the device has been recognized imediately.
Even it is a beginner mistake....maybe it helps :)
This is a fairly common problem. You basically don't have the drivers you need for USB debugging.
There are a few different ways I've had to obtain drivers for phones. The first way you should attempt is to go into the Android SDK and AVD manager and download the Google USB driver debug package.
This may or may not give you the driver you need. If it doesn't you will have to do one of two things. One, add the device details to the driver file you just downloaded. Generally these will be posted on forums/boards discussing your phone type. Secondly, you can download a different driver from another source like the phone manufacturer.
Make sure your account has admin privileges. I installed my Motorola drivers without elevating, and although the install ran smoothly it never associated them to the device. Once I ran as admin, worked like a charm.
Ι had the same problem:
While i had activated the debugging options on my phone (Samsung Galaxy S Duos Black), eclipse couldn't find the device because the usb drivers failed to download or something and so in the Device Manager (win7) i saw only Android and CSC something, all yellow and with no installed drivers.
I tried to download the Samsung drivers manually, but this failed to work.
What REALLY worked was downloading+installing Samsung Kies, connecting my device through usb and at first it failed again to put the drivers, then i disconnected the device, pressed some troubleshooting errors button that was on the main screen (NOT the lite version, the normal one), that took some time, re-connected the device and voila, the drivers were installed successfully and both the Device Manager and eclipse recognised the device.
If you are on Linux you can try on terminal the following steps. Don't forget to have your device plugged in. Use sudo if doest work.
adb kill-server
adb start-server
adb devices (see if device is recognized)
I had the same problem with my LG G3 phone.
I tried to re-install the driver as explained here: http://developer.android.com/tools/extras/oem-usb.html
Nothing helped. Fortunately on the very same page I have found the link to LG firmware site: http://www.lg.com/us/support/software-firmware
So I did the following:
Connect the phone to the PC using the USB cable
Uninstalled the Google's USB driver (My Computer->Management->Devices->Portable Devices->MyPhone: uninstall)
Download driver for my LG G3 phone (LG885) from the LG site
Install this driver
Got on the phone screen request to approve the new RCA key and allow debugging.
Try to Run an Android project in Eclipse.
PROBLEM SOLVED.
I Had the same problem.
I saw that the product was correctly defined under Device Manager, but Eclispe did not show the product in the target.
The easy way was to install Samsung Kies and to see that the following command:
...eclipse\adt-bundle-windows-x86_64\sdk\platform-toolsadb\adb device
gives me some output instead of only "List of devices attached".
once it recognizes the product, use "run configuration" choosing target "Active devices" under "Launch on all compatible devices/AVD's" radio button.
still, you don't get the product on the list as expected but it works.
Good Luck!
I had the same problem on windows with my samsung galaxy device .. installing samsung kies solved the problem for me.
I had loads of problem getting this to work when I switched to a new computer.
I downloaded and installed Kies, but Windows 7 still didn't recognize my device.
My problem was the proxy my company use, Kies tries to download USB drivers in the installation, but fails silently and finishes the installation.
You might have this problem if your USB Driver folder in the installation is empty (i.e C:\Program Files (x86)\Samsung\Kies\USB Driver).
Solution for me: install Kies without a proxy.
Unload EasyTether extension.
This worked for me - look at the part about unloading the EasyTether extension. adb not finding my device / phone (MacOS X) I was able to connect my samsung galaxy note 2 to macbook pro snow leopard.
Download new USB driver for samsung/pc connection here:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
After enabling developer mode and USB debugging of course.
The phone should ask to accept the pc location as secure after USB driver upgrade.
Installing KIES did not fix the problem on my Galaxy Note 3.
I am using Android 2.2 . I am unable to connect my emulator to internet .
When I open my web browser in the emulator it shows the message "Web Page not available" . I have set proxy settings in the emulator (settings -> Wireless & Networks ->Mobile Networks -> Access Point Names). Also , I set proxy settings in eclipse (Windows-> Preferences-> Android-> Launch-> Default Emulator Options). I have read many blogs and forums but I haven't found any solution yet .I am really frustrated .
Please help me out.

You have to start the emulator from the command prompt and supply the proxy server using something like this -
emulator -avd MYAVD -http-proxy http://proxyname:8000
The simplest and the best way is to do the following: This has been done for Android Emulator 2.2 1.Click on Menu 2.Click on Settings 3.Click on Wireless & Networks 4.Go to Mobile Networks 5.Go to Access Point Names 6.Here you will Telkila Internet, click on it. 7.In the Edit access point section, input the "proxy" and "port" 8.Also provide the Username and Password, rest of the fields leave them blank.
How can I connect my Android emulator to the internet, e.g. to use the browser? I've found lots of advice on what do to when your connected through a proxy, but that's not the case here, my machine (Windows 7) is directly connected to the router.
I think some of the answers may have addressed this, however obliquely, but here's what worked for me.
Assuming your problem is occurring when you're on a wireless network and you have a LAN card installed, the issue is that the emulator tries to obtain its DNS settings from that LAN card. Not a problem when you're connected via that LAN, but utterly useless if you're on a wireless connection. I noticed this when I was on my laptop.
So, how to fix? Simple: Disable your LAN card. Really. Just go to your Network connections, find your LAN card, right click it and choose disable. Now try your emulator. If you're like me, it suddenly ... works!
If you are on Mac - try this -
GoTo Apple Icon -> System Preferences -> Network
Click on the gear icon on the and select 'Set Service Order'
Bring the active interface before other interface.
Restart the Android Emulator.
[EDIT]
For more recent version of Android Studio, the emulator you need to use is no longer in the ~/Library/Android/sdk/tools folder but in ~/LibraryAndroid/sdk/emulator.
If while trying the below solution you get the following message "PANIC: Missing emulator engine program for 'x86' CPU.”, then please refer to https://stackoverflow.com/a/49511666 to update your bash environment.
Operating System : Mac OS X El Capitan
IDE : Android Studio 2.2
For some reasons, I wasn't able to access internet through my AVD at work (probably proxy or network configuration issues).
What did the trick for me was to launch in command line my AVD and giving manually the Google public DNS 8.8.8.8.
In your Terminal go to the folder tools of your Android sdk to find the 'emulator' program:
cd ~/Library/Android/sdk/tools
Then retrieve the name of your AVDs :
emulator -list-avds
It will return you something like this:
Android_Wear_Round_API_23
Nexus_10_API_22
Nexus_5X_API_22
Nexus_5X_API_24
Nexus_9_API_24
Then launch the AVD you would like with the following instructions:
emulator -avd NameOfYourDevice -dns-server 8.8.8.8
Your AVD is launched and you should be able to use internet.
My platform: Mac OS 10.6.4
Eclipse: 3.6
I had a similar problem where my map app background was grey (no tiles) and the browser was unable to connect to the internet.
Within Eclipse I went to Run Configurations -> Target and added "-dns-server X.X.X.X" and everything worked fine afterwards. (obviously X.X.X.X was the IP address for my DNS server).
In order to use internet via proxy on emulator try these steps it Worked for me:
Go to settings->Wireless & networks->mobile networks->Access Point Names.
Press menu button. an option menu will appear.
from the option menu select New APN.
Click on Name. provide name to apn say My APN.
Click on APN. Enter www.
Click on Proxy. enter your proxy server IP. you can get it from internet explorers internet options menu.
click on Port. enter port number in my case it was 8080. you can get it from internet explorers internet options menu.
Click on User-name. provide user-name in format domain\user-name. generally it is your systems login.
Click on password. provide your systems password.
press menu button again. an option menu will appear.
press save this and try to open your browser. I think it has helped u?
righ click on the Project in Eclipse
select Run As -> Run Configurations ...
select Android Application and then select "target" tab
Looking for "Additional Emulator Command Line Options" and put this command line to text box
-http-proxy http://< username >:< password >#< hostname >:< port >
There are different solutions to this problem . One of these , i will show you on my experiment and outcomes seen on results using a recent android studio and AVD images downloaded 2017.
First thing you have to do is launch your AVD from android studio.(in my case i choose NEXUSAPI25 android 7.1 image)
Goto Settings->Wirless and Networking - > Cellular Network - > Access Points -> (+) press add - > enter the following if you dont have NTLM proxy or proxy at all (that means you are directly connected)
a. add apn name as myAPN
b. add apn server => www
c. save and try browsing the internet.
if this doesn work add 'ANDROID_SDK_ROOT' in you environment variable
Then , launch AVD using emulator command as follow
emulator -avd Nexus25 -dns-server 8.8.8.8
For those who use NTLM proxies , i will show you how it work for me next.
add your Android_sdk_root path into your environment variable. THis make command line code read succesfully like using AVD names and so on.
Launch your emaulator using the following command
>emulator -avd Nexus_5X_API_25 -http-proxy http://username:password#ipaddress:port
ENTER
Have you tried starting the emulator with administrative privileges? It worked for me, I'm running Windows 7 64bit)
In my case I just had to launch the Android virtual device (AVD) from the "Android SDK and AVD Manager", and it was working
If you are behind a proxy in the SDK Manager, under Tools -> Options, do NOT configure the proxy settings.
When you run from the command line add -http-proxy:
emulator.exe -avd YOUR_AVD_NAME_HERE -http-proxy PROXY:PORT
Worked for me.
I also experienced the same problem.
The simplest solution I found out is:
Go to your Android\Sdk\emulator folder and open command prompt.
Type emulator -list-avds to see available emulator names.
Type emulator -avd name-of-your-device -netdelay none -netspeed full
-dns-server 8.8.8.8 command and press enter.
I encounter this issue when I first run the simulator, I solved it by setting the dns server with
Library/Android/sdk/platform-tools/adb shell getprop net.dns1
get the current dns server of simulator 10.0.2.3
Then set it to my lan dns server
Library/Android/sdk/platform-tools/adb shell setprop net.dns1 192.168.1.1
I had similar problem. I have installed an application that required INTERNET permission (and used it), and all of sudden, worked.
Guys, check also whether if you are not connected through a VPN somewhere, because it also can disturb the Internet connection.

In eclipse go to DDMS
under DDMS select Emulator Control ,which contains Telephony Status
in telephony status contain data -->select Home , this will enable your internet connection ,if you want disable internet connection for Emulator then --->select None
(Note: This will enable internet connections only if you PC/laptop on which you are running your eclipse have active internet connections.)
After reading this I decided to look at my "NICs". I put this in quotes because like many I am running virtual nics for devices like Hamachi and Virtual Box. After I disabled Hamachi I am able to use the internet. My guess is that the emulator picks the first available nic regardless of whether it is virtual. Now to find out if I can rearrange my nic order without tearing my box down.
Windows 7 32bit
My Service Order preferences were correct (Wi-Fi was first) but still could not connect.
Answer was to turn off the Thunderbolt Bridge:
System Preferences > Network > Thunderbolt Bridge
Then set Configure IPv4 to off and Apply your changes.
No need to screw around with Access Points in the emulator.
I solved it my disabling all network connections except the wifi connection I was using, then setting the properties on that one remaining enabled connection to have statically assigned DNS addresses. (no DHCP) This was on Win7 64bit
Thanks for the pointers. They really helped. The "Firewall" word clicked an idea in my mind.
I have a Windows XP machine with WIFI connection and no proxy. I have Norton Internet Security running on my machine which has a Smart Firewall. This Smart Firewall manages programs' access to network, including emulator.exe. I went into Settings -> Program Control and then granted full access to emulator.exe. After this I started Android Emulator and bang... I could connect to internet.
Hope this helps new folks.
~Saggy
Within the Android emulator, turning Airplane Mode on, then off again worked for me.
If you're on MacOS with 2.2 and you keep seeing an error about data connectivity, try the above, it works.
I removed all the network interfaces via Sys Prefs except LAN
Even thought my DNS is provided by DHCP, I retyped DNS with just one server
I used -http-proxy on the command line to specify one
It starts working at the office. Phew.
I think sometimes it's just enogh to simply restart the virtual device. :-)
I had the same problem on my virtual windows 7.
Go to Network Connections
Alt > Advanced > Advanced Settings...
In the second tab bring the internet networks interface on the top
hope it's helpful
thanks to
I had this issue due to a network change after I opened the emulator. If you change your WiFi after you start the emulator, you only need to restart the emulator to get internet access
yes--in win 7 start the emulator with administrator privs and all will be well--or at least you'll get the wireless going in android.
I had a similar problem on Win7 64 bit. Tried disabling my hamachi and virtualbox adapters and didn't work. Tried starting avd as admin and didn't work. In the end I disabled the teredo tunneling adapter using the info on this site and it worked:
http://www.mydigitallife.info/2007/09/09/how-to-disable-tcpipv6-teredo-tunneling-in-vista/
I found that starting the emulator with 'wipe user data' checked cleared this problem up for me after I rebuilt my dev machine from Vista x64 to Win7 x64.
it appears there might be a few reasons why there might be no internet connection for an emulator, in my case i was working from home where i have a wireless connection then came into the office and plugged in direct, however although my wireless connection was disconnected it was not disabled resulting in no emulator connection. my understanding is that when it starts up it looks for a network adapter and if there is any conflict here it might result in no internet connection. to resolve go to Start > Settings > Network Connections right click on Wireless Network Connection (if you are not using wireless) and select disable
I am not using a proxy...however I am using a script...Is there anyway around this. I am behind a company firewall
I'm not sure if this is your issue, but here's how I fixed mine.
I always had this "No DNS servers found" error when starting the emulator and did a lot of research on google to no avail. Anyway, I found a post somewhere (can't find it anymore) that was saying that the number of NICs, number of DNS entries could affect the emulator. Also, knowing that the emulator uses a Windows API function (GetNetworkParams()) to resolve DNS entries, I couldn't rely on the %WINDOWS%\System32\Hosts file.
However, I did went in the NICs properties (on Windows 7) to find that I was specifying a static IP, but no DNS entries. So, I got the DNS entries from my router and plugged them in the NICs property. I restarted the emulator and it is now using the correct DNS entries!
I can use my internet connection with the emulator now, and it works wonders!
Hope it helps!
I thought I experienced issues with connecting my emulator to the internet but it turned out to be problems with the code I was using. I know its obvious but in the first instance try the browser on the emulator to confirm you have no internet access. I would have saved an hour if I had done that first.
