Answer:

Download Androidx86 from this This is an iso file, so you’d
need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux
instead of Other.

After creating the virtual machine set the network adapter to ‘Bridged’. ·
Start the VM and select ‘Live CD VESA’ at boot.

Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1
& Alt+F7 to toggle) and use the netcfg command to find this.

Now you need open a command prompt and go to your android install
folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.

Type adb connect IP_ADDRESS.
There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.

In VirtualBox screen, go to Devices>USB devices. Select your dongle.

Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.

Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.

Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number
then select port mode as disconnected click ok. now, start virtual
machine. Under Devices -> USB Devices -> you can find your laptop
bluetooth listed. You can simply check the option and start testing
the android bluetooth application .
