// Create a message from pud
Messages [I] = SmsMessage. createFromPdu (pdu );

}

// Determine the length of the text message content. If the length is greater than 70, an error occurs. Therefore, this step is very important.
If (content. length ()> = 70 ){

SmsManager. sendTextMessage (phoneNumber, null, mMsg, null, null );
}
} Else {

SmsManager. sendTextMessage (phoneNumber, null, mMsg, null, null );

SmsManager. sendTextMessage (phoneNumber, null, content, null, null );
}
}

}
The above code is very simple. After the mobile phone receives the text message, the android system will send a short message broadcast. His action is android. provider. telephony. SMS_RECEIVED: our broadcast receiver can filter this action. In this way, we can get the content of the text message, the sender of the text message, and the sending time of the text message, then you can call android to send a text message. You have the permission to send the text message <uses-permission android: name = "android. permission. SEND_SMS "/>
