SMS Emulation
The Android emulator console lets you generate an SMS message and direct it to an emulator instance. Once you connect to an emulator instance, you can generate an emulated incoming SMS using this command:
sms send <senderPhoneNumber> <textmessage>
where <senderPhoneNumber>
contains an arbitrary numeric string.
The console forwards the SMS message to the Android framework, which passes it through to an application that handles that message type.
