Try to explain these things to ‘The Common People’.

Wouldn’t an AVI or MP4 container with XviD or H264 or DivX or … + MP3-sound have been easier to work with?
At least sth easily cutable, joinable, extractable?!

Is there anyway to connect two mono external mic’s to record on the Droid in stereo? I know the mic mini on the Droid is mono but what about having a Y “merger” go into the USB port?

Hi, me again.
Turns out the problem is with where the new object of the MediaRecorder is created. Since the object is released every time the stop method is called, if a new method is created in the start method instead, then things would work fine.
Thanks for the code

Oh to add to my previous post… I already declared permissions in manifest and I am testing on the device rather than the emulator.

Hi Ben and others,

Thanks for the code! I also got the unsupported parameter error, but my audio clip is still recorded and it plays fine
However I realized that if I want to record another clip, the app crashes without catching any exceptions… does anybody know why? Logcat shows a bunch of numbers and I have no idea what they mean:

Those who try on Emulator should know that, voice recording via emulator is not supported. You’ll need real dev device to test this code.

BTW anyone know how to pause the recording?? since recorder.pause() is not available, something like dat??
