Answer 1

您從捆綁中獲得的對象爲null final Object[] pdusObj = (Object[]) bundle.get("pdus");請重新檢查。

Answer 2

您可以使用此代碼

public class TextMessageReceiver extends BroadcastReceiver { 

    public void onReceive(Context context, Intent intent) { 
     Bundle bundle = intent.getExtras(); 
     Object[] messages = (Object[]) bundle.get("pdus"); 
     SmsMessage[] sms = new SmsMessage[messages.length]; 
     for (int n = 0; n < messages.length; n++) { 
      sms[n] = SmsMessage.createFromPdu((byte[]) messages[n]); 
       } 
     for (SmsMessage msg : sms) { 
        //message body 'msg.getMessageBody()' 
        //message sender 'msg.getOriginatingAddress()' 
        String number = "tel:" + msg.getOriginatingAddress(); 
       Intent callIntent = new Intent(Intent.ACTION_CALL,Uri.parse(number)); 
       startActivity(callIntent); 
       } 
     }
