Send SMS in Android

Send SMS in android, we can send text messages in two ways, using either SMSManager API or Intents.

// Using SMSManager API

SmsManager s = SmsManager.getDefault();
s.sendTextMessage(number,null,Message,null,null);

// Using Intents

Intent i = new Intent(Intent.ACTION_VIEW);
i.putExtra("address", new String[]{txtMobile.getText().toString()});
i.putExtra("sms_body",txtMessage.getText().toString());
i.setType("vnd.android-dir/mms-sms");

// MainActivity.java

// Using sms manager

package com.androidaura.sms;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
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 MainActivity extends AppCompatActivity {

    private EditText mobile;
    private EditText message;
    private Button btnSms;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mobile = (EditText)findViewById(R.id.mobileNo);
        message = (EditText)findViewById(R.id.msgText);
        btnSms = (Button)findViewById(R.id.btnSend);


        // Using sms manager
        btnSms.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                try{
                    SmsManager smgr = SmsManager.getDefault();
                    smgr.sendTextMessage(mobile.getText().toString(),null,message.getText().toString(),null,null);
                    Toast.makeText(MainActivity.this, "SMS Sent", Toast.LENGTH_SHORT).show();
                }
                catch (Exception e){
                    Toast.makeText(MainActivity.this, "Failed", Toast.LENGTH_SHORT).show();
                }
            }
        });
       }
