Hello All, I have had this error both on emulator and a Motorola Droid while using a WIFI connection. I have surrounded the http request with WIFI state checks and before and after WIFI is reported state 3 (WIFI_STATE_ENABLED) and a connection speed of 54 . I have also confirmed, using an adb shell with the emulator, that the emulator cannot ping the website in question giving a domain resolution error. To compare notes with Ankur, is the server on your LAN and the IP used internal? mine is.
I have also tried AndroidHttpClient which does work on the same url. -Dan On Jan 12, 12:23 pm, Ankur Avlani <[email protected]> wrote: > True, I agree with what you say.
