Sending SMS in Android [closed]

Answer 1

If everything is fine (code, permissions in the manifest file), open two emulator windows (they will be something like 5554:TestDevice1 and 5556:TestDevice1).

Now, if you are installing your application to 5554, send a message to 5556 and check in another emulator.

I really don't get why would you nest the sendSMS method anyway - the code works for me. Try checking if you got the

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>

permission set in your file and try this code instead:

package SMSApp.com;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class SMS extends Activity {
    /** Called when the activity is first created. */

    Button btnSendSMS;
    EditText txtPhoneNo;
    EditText txtMessage;

    @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();
            }

        });
    }

    private void sendSMS(String phoneNumber, String message)
    {
        String SENT = "SMS_SENT";
        String DELIVERED = "SMS_DELIVERED";

        PendingIntent sentPI = PendingIntent.getBroadcast(SMS.this, 0,
            new Intent(SENT), 0);

        PendingIntent deliveredPI = PendingIntent.getBroadcast(SMS.this, 0,
            new Intent(DELIVERED), 0);

        //--- When the SMS has been sent ---
        registerReceiver(new BroadcastReceiver(){
            @Override
            public void onReceive(Context arg0, Intent arg1) {
                switch (getResultCode())
                {
                    case Activity.RESULT_OK:
                        Toast.makeText(SMS.this, "SMS sent",

                        break;
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                        Toast.makeText(SMS.this, "Null PDU",
