Team, I set up an android emulator in my mac [Api level 28, os 9]
I can see by default it is connected to 'androidwifi'.
How do i connect the same emulator to my corporate wifi so that i can test my app inside that.
Your emulator will use your computer's hardware to emulate every relevant aspect of the hardware of a real device. Likewise, the "androidwifi" network is a simulation of the actual wifi network that your computer is connected to.
If you want to change the settings and test different speeds/latency/etc you can do it via the emulator settings. Some of them (eg. netspeed) can be further configured manually with commands. Here's a list from the developer's guide.

Device : Google Nexus 5 (Un-rooted)
Host Machine : Window 7
I want to Access Android Device as a Modem (using COM or Modem Port) and eventually pass AT Commands using HyperTerminal/Teraterm.
So after connecting the device to a Windows Box, The Device gets detected under Device Manager, but doesn't show any COM Port (other than the default COM0).
On right click and update driver, It shows it cannot find drivers.
I have tried the following options, but no luck with any.
Tried this on a rooted Nexus 5, but doesn't expose which /dev/smdX to use. Tried all combinations, didn't work.
Tried the Google USB Drivers from the Google Android's Website. No changes.
From here. I Installed drivers from LG Electronics, No changes in COM Port.
Universal Naked Driver helped me get to ADB Shell interface, but
thats not what I want.
In all of the Above procedure USB Debugging was enabled (Just saying).
I also heard the phone has to put into Modem mode to fire AT Commands.
If so, How do I do that ?
Or Is this a device driver Issue ?
Conclusion:
I want to access the Modem of the Android Device and fire AT Commands to it.
Could you please tell what am I missing ?
Any help on this would be really appreciated.
It's difficult to give an exact answer to this question, because it depends on how the manufacturer has implemented the device drivers. Unfortunately, there is a lot of information that isn't in the public domain.
It is possible, that the manufacturer has implemented some code to convert the device to a modem. Doing this yourself is device-specific, and proprietary. You might be able to get hold of a converter, for example bundled with the manufacturer's dashboard application for the PC, if such a thing exists.
Some devices don't expose the modem port at all. They may be visible as a network adapter, or as an always-connected LAN connection. If the device is visible as a network adapter, then you can access it via Windows Mobile Broadband API, or via MBIM for some newer devices.
To check if the device is visible as a network adapter, and get information about it, open a cmd box and type
netsh mbn show interfaces
Windows Mobile Broadband API doesn't give as many details as a good AT command set, but performs basically the same functions. MBIM is an industry standard interface with similar functionality, available on the Windows 8+ desktop via the Mobile Broadband DeviceServices API, for devices that support it.
If the device shows as an always-on LAN connection, there is probably a proprietary, high level interface for mobile functionality.
Driver behaviour can differ for different operating systems. If you have the chance to try the device on Windows Vista, 7 and 8, you may see different behaviour.
How to enable WiFi on Android emulator? I have tried to find this but everyone is confusing WiFi with 3G.
Wifi is not available on the emulator if you are using below of API level 25.
When using an AVD with API level 25 or higher, the emulator provides a
simulated Wi-Fi access point ("AndroidWifi"), and Android
automatically connects to it.
More Information:
https://developer.android.com/studio/run/emulator.html#wifi
Apparently it does not and I didn't quite expect it would. HOWEVER Ivan brings up a good possibility that has escaped Android people.
What is the purpose of an emulator? to EMULATE, right? I don't see why for testing purposes -provided the tester understands the limitations- the emulator might not add a Wifi emulator.
It could for example emulate WiFi access by using the underlying internet connection of the host. Obviously testing WPA/WEP differencess would not make sense but at least it could toggle access via WiFi.
Or some sort of emulator plugin where there would be a base WiFi emulator that would emulate WiFi access via the underlying connection but then via configuration it could emulate WPA/WEP by providing a list of fake WiFi networks and their corresponding fake passwords that would be matched against a configurable list of credentials.
After all the idea is to do initial testing on the emulator and then move on to the actual device.
As of now, with Revision 26.1.3 of the android emulator, it is finally possible on the image v8 of the API 25.
If the emulator was created before you upgrade to the latest API 25 image, you need to wipe data or simply delete and recreate your image if you prefer.
Added support for Wi-Fi in some system images (currently only API
level 25). An access point called "AndroidWifi" is available and
Android automatically connects to it. Wi-Fi support can be disabled by
running the emulator with the command line parameter -feature -Wifi.

In theory, linux (the kernel underlying android) has mac80211_hwsim driver, which simulates WiFi. It can be used to set up several WiFi devices (an acces point, and another WiFi device, and so on), which would make up a WiFi network.
It's useful for testing WiFi programs under linux. Possibly, even under user-mode linux or other isolated virtual "boxes" with linux.
In theory, this driver could be used for tests in the android systems where you don't have a real WiFi device (or don't want to use it), and also in some kind of android emulators. Perhaps, one can manage to use this driver in android-x86, or--for testing--in android-x86 run in VirtualBox.
The emulator does not provide virtual hardware for Wi-Fi if you use API 24 or earlier. From the Android Developers website:

What's not supported
The Android Emulator doesn't include virtual
hardware for the following:
Bluetooth
NFC
SD card insert/eject
Device-attached headphones
USB
The watch emulator for Android Wear doesn't support the Overview (Recent
Apps) button, D-pad, and fingerprint sensor.

If your simulator is not connecting to wifi and your in a mac(I don't know how to add DNS in windows) just go to
Network -> advance -> DNS and add 8.8.8.8 and 8.8.4.4 the close the android simulator, open android studio, select the simulator and click on cold reboot then your simulator will be connected to wifi.
I am trying to debug on a USB connection to several different Sony tablets (particularly the P, which is listed as supported). I can debug on a smart phone, but the tablet doesn't show up as a connected device when I try to run my app in Eclipse. I have checked that the settings of the tablet have Applications->Unknown sources, and Applications->Development->USB Debugging
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 Tablet/Phone type. Secondly, you can download a different driver from another source like the Tab/Phone manufacturer.
Here a Youtube video how to install Sony Tablet S & P
Or the app you are developing has set the target higher than your tablet supports. Then it also won`t show up in the AVD Manager.
In case you wont get proper drivers for your tablet you can try adb over network.
Connect your device to wifi as well as your computer.
turn on ADB over network in Options for developers (maybe some ROM dont support it). Eventualy you can enable this using specific commands on your tablet.
on your computer run terminal and use: adb connect <ip>:<port> where <ip> refers to IP of your tablet and <port> refers to port on which adb is listening (usually 5555).
run adb devices to verify that device is connected
i want to develop android application in which runs in my pc and connects to different android devices through wify and communicate with them,so i am trying to connect an ad-hoc network through my android phone.i found that this is supported only in android 4.0.so i want to test this in emulator,how can i connect emulator in a ad-hoc wifi network,if it is possible,plese help me to conncect emulator to a ad-hoc network created by my Laptop
No, my guess is that it's not.
It's not listed as a Property you can set when you create a new emulator. Neither is it listed in the Emulator Control under DDMS.
Besides, even if it were in there (which it's not), you'd probably still need two different computers to simulate the connection (not just one pretending to be connecting to itself).
