How to tell the Android Emulator to use an external hardware device (e.g. a microphone)?

Is 开发者_运维知识库it possible to tell the Android Emulator to use external hardware? In my case, I want to use a Microphone for input for an app I'm developing...

I know about the Emulator start-up commands, but I can't seem to get these working...

Is there anybody who can tell me more about how to use the start-up commands trough Eclipse? Or how to determine which backend I have to specify when using let's say the -audio-in <backend> start-up command...

I really need this to work, as I can't debug on the phone I use to test my apps...

For Additional(Start-up) command below is resolution:

got to project->run->run configuration->target->scroll down you will see Additional emulator Command Line Options.......give your additional command here..android will launch emulator with youe specified command
