replay to message in android

if you please I just want to know how can I replay to sms automatic to a message received on the mobile in my application I could received the开发者_JAVA百科 sms only but i could not auto replay the sms.in android

Well, you create a class that extends the BroadCastReciever class. In this class, override the onReceive method to intercept received messages. It will be in this method that you will have to send your automatic reply.

This you can do by using intents and starting the activity to send your sms. You can refer to the following links for details on the same:

The second link explains in detail what ive tried to explain above.

Hope this helps.
