I don't know if the source for the android tools has been made
available or will be made available, but that would be something to
watch for in the future if you needed some way to write to your
computers hard drive. You could also try to use the sdcard. There
might be a way to mount it in your computer. That way, you could write
to the sdcard from your client code, then access it in your computer.
/data/data/<your.app.namespace>/files/out.txt is on the emulator file
system. You can log in with "adb shell" or you can copy the file from
the emulator with adb pull.
So with your http post, you were using the actual ip address of your
computer in the url? That should work.
