I wonder if it possible to test offline mode on android emulator? Im trying to use ddms for this. But when i set telephony status data to "denied" or "unregistered" nothing changes and application still can receive data.
For Telephony Offline/Online Mode :
You can Toggle cell networking on/off by pressing F8
You can refer full Controls Of Emulator here : http://developer.android.com/guide/developing/devices/emulator.html#controlling
