Android廣播接收短信的簡單實現

 

說明： 接受短信廣播，由Intent解析出短信內容明文， intent中的短信時已pud形式傳出的，即byte[][]二位數組，

需要轉化出明文SmsMessage.createFromPdu(pdus[i])

廣播接收器：

public class SmsReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
if (intent != null && intent.getAction() != null) {
if (intent.getAction().equals(Intents.SMS_RECEIVED_ACTION)) {
SmsMessage[] msgs = getMessagesFromIntent(intent);
// to use this SmsMessage

String messageBody = "";
for (SmsMessage message : messages) {
messageBody += message.getMessageBody();
}

Log.i("MSG", messageBody);
}
}

}

/**

* Read the PDUs out of an {@link #SMS_RECEIVED_ACTION} or a
* {@link #DATA_SMS_RECEIVED_ACTION} intent.
*
* @param intent
* the intent to read from
* @return an array of SmsMessages for the PDUs
*/
public static final SmsMessage[] getMessagesFromIntent(Intent intent) {
Object[] messages = (Object[]) intent
.getSerializableExtra("pdus");
if (messages == null) {
return null;
}
byte[][] pduObjs = new byte[messages.length][];

for (int i = 0; i < messages.length; i++) {
pduObjs[i] = (byte[]) messages[i];
}
byte[][] pdus = new byte[pduObjs.length][];
int pduCount = pdus.length;
SmsMessage[] msgs = new SmsMessage[pduCount];
for (int i = 0; i < pduCount; i++) {
pdus[i] = pduObjs[i];
msgs[i] = SmsMessage.createFromPdu(pdus[i]); //解析每一段pdu字節數組，返回解碼明文
}
return msgs;
}

}

注意： manifest中聲明權限：

//接收短信必須的權限

//讀系統短信權限

//寫系統短信權限
