Android emulator does not support multicast currently however I need to test an application that needs multicast packets. I want to do it on Emulator.
Is there a way to receive multicast packets on Android Emulator? I am open to writing some code as an android app.
At the present time, 2 years later, multicast packets still not supported on Android Emulator.
Android Documentation
Multicasting is still not supported by Android studio's emulator, however, you can use Genymotion. Using Genymotion, create two new emulated devices and set their "network mode" to "Bridge". Like this, the emulator will use your computer's network. By reusing your own network you can use multicasting if it is supported by your network. A nice bonus is that your emulators can even communicate with real devices on your network.

now i have 1 smartphone and 1 laptop and there is no wifi access here, can i run my flutter project through my smartphone hotspot. just like companion on kodular
note: I don't use a USB cable for some reason
You can use Wifi AVD plugin to debug your application wirelessly but you have to connect your device via USB for the first time.
Please check this out. You can use wireless adb connection

I'm want to see the traffic sent and received from an app installed on android emulator while being connected to a private VPN
currently i'm using the loadrunner recorder to sniff this traffic of the app on the emulator but i does not show any requests or responses.
on the other hand when i try to record any of the available websites while connected on the vpn on the google chrome the loadrunner capture these traffic normally.
Is there any configurations that should be adjusted on the emulator? as in my opinion that the IP of the emulator is not the same as the one of the VPN.

You need your proxy recorder to be in the same network as your emulator which is generating HTML. Then you can have a "man in the middle" proxy recording of the behavior.
If you emulator is on VPN and the host of your recorder is not, then you are likely out of luck. However, connect your parent OS to the VPN, which is also running VUGEN and the Emulator, then set your emulator to the recording proxy of VUGEN and you are likely golden.
I wrote an app which runs on two android tablets at the same time. The app enables both devices to communicate with a java server which is running on the pc, via WLAN socket communication.
The problem with the WLAN connection is that it doesn't always seem to be reliable. So I wanted to setup a socket communication to the server via USB cables.
My problem no is how to connect TWO android devices to the server via USB cables. I found this tutorial for connecting ONE device to the server via ADB, but I see no possibility using this approach for two devices:

Has anyone an idea how to solve it? Thanks!
If your tablet is runs ICS or newer Android OS, then it is very likely that it has OTG capable micro-USB socket, and you can add a USB-Ethernet dongle, and then connect the 2 tablets to your PC over ethernet, instead of USB. This, might be the most elegant solution.
Of course, you'd need a switch (or hub) to connect them together. Also note that, not all USB-Ethernet dongles may work out-of-the-box. You might have to experiment with few models, especially the el-cheapo ones to get them to work.
Does Android support android.internal.telephony.xxx where xxx=3G WCDMA or CDMA.
I know it supports GSM. Would GSM package work with a 3G WCDMA Vendor RIL?
I looked at the radio debug logs using adb from a Nexus One connected to AT&T 3G network. The log showed that the GSM package was being used while in a 3G call. So it looks like a separate WCDMA package is not needed.
I need to prototype an Android application which communicates to external hardware using serial I/O. Can the emulator send and receive serial data over a PC's com port?
The Android emulator itself supports this feature, I see people use
"emulator -qemu -serial COM1" on Windows PC
or
"emulatro -qemu -serial /dev/ttyS0" on Linux PC
I have not tried it by myself yet, but that is the way in the big picture.
I came across this:
http://code.google.com/p/android-serialport-api/
this library will let you use Java to access the serial port on your Android device
