Answer 1

Try this:

Add this inside manifest.xml:

main.xml:

MainActivity:

public class SMS extends Activity 
{
    Button  btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        

        btnSendSMS = (Button ) findViewById(R.id.btnSendSMS);
        txtPhoneNo = (EditText) findViewById(R.id.txtPhoneNo);
        txtMessage = (EditText) findViewById(R.id.txtMessage);

        btnSendSMS.setOnClickListener(new View .OnClickListener() 
        {
            public void onClick(View  v) 
            {                
                String  phoneNo = txtPhoneNo.getText().toString();
                String  message = txtMessage.getText().toString();                 
                if (phoneNo.length()>0 && message.length()>0)                
                    sendSMS(phoneNo, message);                
                else
                    Toast.makeText(getBaseContext(), 
                        "Please enter both phone number and message.", 
                        Toast.LENGTH_SHORT).show();
            }
        });        
    }    
}

sendSMS() function:

public class SMS extends Activity 
{
    //...

    /** Called when the activity is first created. */
    @Override

        sms.sendTextMessage(phoneNumber, null, message, pi, null);        
    }

        PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
