Hi,

1) Well, There is no Method for the Sms Connection which you could retrieve - isAlive().
A solution in which you could do is Wrapping your SMS code over Thread or Timer+Tasker(for Scheduling your Sending.

This is only an example. for sending text message over sms

import java.io.IOException;
import javax.microedition.io.Connector;
import javax.wireless.messaging.MessageConnection;
import javax.wireless.messaging.TextMessage;

/** Sends an SMS message */
public class SMSender implements Runnable {
  private String smsReceiverPort;
  private String message;
  private String phoneNumber;

  public SMSender(String smsReceiverPort) {
    this.smsReceiverPort = smsReceiverPort;
  }

  public void run() {
    StringBuffer addr = new StringBuffer(20);
    addr.append("sms://+");
     addr.append(phoneNumber);
    // String address = "sms://+8613641301055";
    String address = addr.toString();

    MessageConnection smsconn = null;
    try {
      // Open the message connection.
      smsconn = (MessageConnection) Connector.open(address);
      // Create the message.
      TextMessage txtmessage = (TextMessage) smsconn
          .newMessage(MessageConnection.TEXT_MESSAGE);
      txtmessage.setAddress(address);// !!
      txtmessage.setPayloadText(message);
      smsconn.send(txtmessage);
    } catch (Exception e) {
      e.printStackTrace();
    }

    if (smsconn != null) {
      try {
        smsconn.close();
      } catch (IOException ioe) {
        ioe.printStackTrace();
      }
    }
  }

  public void send(String message, String phoneNumber) {
    this.message = message;
    this.phoneNumber = phoneNumber;
    Thread t = new Thread(this);
    t.start();
  }

}

2) impossible at the moment.

Hello prashantpersistent,

2.is there any solution to check whether device battery power is low ?

Currently this is possible only with S60 3rd Edition, Feature Pack 2 devices by using this system property string:

"com.nokia.mid.batterylevel"

Using System.getProperty("com.nokia.mid.batterylevel") returns the battery charge level of device. The property value is the actual battery level in percentage.
