Android - Emulator Console and multiple instances of emulator
My previous post on the tip for redirecting UDP had another tidbit that Digit eluded to and that is using the telnet to get to the Emulator Console. This page in the Android documentation give more information on the Console.
What is enlightening is that it state that upto 16 devices can be running at any time. Also, of note is that there is a possible security problem in that it listens on all networks, but that in the future it will only listen on localhost.
As for supporting multiple devices, see this section. To allow multiple instances to have their own “areas” you can the emulator with different options, these include -data, -ramdisk and -sdcard.
