我的目標是創建一個短消息服務器，能夠發送短信發送短信請求的用戶...我創建第一個廣播接收器接收短信，並獲得發件人數量和消息體。 與該機構（無卷），與滾首先在這個人.. 的標記沒有結果我通過郵件正文從廣播接收器的活動另一項活動.. 這裏是我的廣播接收器代碼：android短信發送到收到號碼
public class IncomingSms extends BroadcastReceiver{
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
if(arg1.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
Bundle bundle = arg1.getExtras();
SmsMessage[] msgs = null;
String msg_from;
String msgBody;
if(bundle!=null) {
try {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for(int i=0;i<msgs.length;i++) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
msg_from = msgs[i].getOriginatingAddress();
msgBody = msgs[i].getMessageBody();
Toast.makeText(arg0, "SenderNum :" + msg_from + "msg :" + msgBody, Toast.LENGTH_LONG).show();
Intent in = new Intent("SmsMessage.intent.MAIN");
in.putExtra("get_msg", msgBody);
arg0.sendBroadcast(in);
}
msg_from = msgs[0].getOriginatingAddress();
String msg = arg1.getStringExtra("string");
Toast.makeText(arg0, "Sms sent", Toast.LENGTH_LONG).show();
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(msg_from, null, msg, null, null);
} catch(Exception e) {
Log.d("Exception caught", e.getMessage());
}
}
}
}
}`
和之後，郵件正文將與滾動號碼的現有數據庫進行比較，如果發現傳遞這串標記給broadcastreceiver發送短信給用戶... 這是我的活動代碼：
