I can't write to the C: drive?! That sucks. Are there any other
alternatives? I need the Android app to relay info to the outside
world (app write data that outside programs consume). These are the
two ways I came up with : ).
When I said I couldn't find this file, I meant the computer file
system. How do I access /data/data/<your.app.namespace>/files/
out.txt? Can an independent java program be able to read from this
file?
As for the http post, from an independent client, it works (I had to
of course change 0.0.2.2 to localhost). The post hits a webapp
implemented in Web Works. I have this code sitting inside the
onCreate() method of an Activity. It doesn't give any on screen
exceptions. Just no result on the server side.
Thanks again,
Yi
