about test the sound recording function and View new created files in emulator

I am making a program for recording sound. I have completed the basic record functions and the interface. However, when I test it, I have no idea how to make use of 开发者_如何学JAVAthe emulator to test if the program really work. Shall my computer equip with mic to test it?

Other than that, since my program will create a .3gp audio file in a designated path, but I have no idea how to view the folder in the emulator as i dont find something like a file manager in it... could anyone advice?

Thank you very much for your help.

I was also trying to do same thing, recording sound to a file. The created file should be displayed on the Music Player. In my case, it is appearing in the Music Player media contents list.
