[android-developers] Re: Can GPS work without internet access in Android phone?

Hi, lbendlin,

Thank you for your reply.
I am really facing this issue.
When I turn off the Network (WiFi and/or cell network), the app cannot
obtain (GPS / A-GPS) position.
Then I turn the network on, it can get the (GPS / A-GPS) position
successfully.
What's wrong?

Thanks and Regards,
Kenneth Won
