Send SMS Android SDK

Integrate android sdk to Send SMS from Mobtexting

Getting Started

Gradle

Step 1. Add the JitPack repository to your build file

allprojects {
  repositories {
    maven { url 'https://jitpack.io' }
  }
}

Step 2. Add the dependency

dependencies {
  implementation 'com.github.mobtexting:mobtexting-android:v1.0.3'
}

define API KEY and Sender ID in Manifest file inside Application tag

  <meta-data android:name="mobtexting.api_key" android:value="@string/mobtextingapikey" />
  <meta-data android:name="mobtexting.sender_id" android:value="@string/mobtextingsenderid" />

Usage (send SMS)

public class MainActivity extends AppCompatActivity implements MobtextingInterface{
    private Mobtexting mobtexting;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        //create instance of Mobtexting class
        mobtexting=new Mobtexting(this);
        
        //send the SMS
        mobtexting.sendSMS("This is a test","7488******",this);
    }

    @Override
    public void onResponse(ServerResponse serverResponse) {
        Log.d("response",serverResponse.getStatus()+"  "+serverResponse.getDescription()+"  "+serverResponse.getSmsId());
    }

    @Override
    public void onError(ModelError modelError) {
        Log.d("response",modelError.getStatus()+"  "+modelError.getDescription());
    }
}

Usage (how to verify OTP)

Step 1. Generate six digit random OTP in MainActivity class.

public class MainActivity extends AppCompatActivity implements MobtextingInterface{
    private Mobtexting mobtexting;
    private String otp_sixdigit;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Generate six digit OTP
        otp_sixdigit=String.valueOf(generateSixDigitRandomNumber());

        mobtexting=new Mobtexting(this);
        mobtexting.sendSMS("This is a test "+otp_sixdigit,"7488792140",this);
    }

    //Generate 6 digit number
    private int generateSixDigitRandomNumber(){
        Random rnd = new Random();
        int n = 100000 + rnd.nextInt(900000);
        return n;
    }

    @Override
    public void onResponse(ServerResponse serverResponse) {
        Log.d("response",serverResponse.getStatus()+"  "+serverResponse.getDescription()+"  "+serverResponse.getSmsId());

        //pass the 6 digit OTP to OTPActivity class
        Intent intent=new Intent(getBaseContext(),OTPActivity.class);
        intent.putExtra("otp",otp_sixdigit);
        startActivity(intent);
    }

    @Override
    public void onError(ModelError modelError) {
        Log.d("response",modelError.getStatus()+"  "+modelError.getDescription());
    }
}

Step 2. After successful response, pass the generated OTP to OTPActivity class.

public class OTPActivity extends AppCompatActivity {
    private EditText otpEditText;
    private Button btnVerify;
    private String otp;

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

        otpEditText = (EditText) findViewById(R.id.otpEditText);
        btnVerify = (Button) findViewById(R.id.btnVerify);

        //receive the 6 digit generated OTP from previous activity
        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            otp = extras.getString("otp");
        }

        //button click listener
        btnVerify.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //check the OTP verification
                if ((otp != null) && (otp.equals(otpEditText.getText().toString().trim()))) {
                    Log.d("verified","OTP verified successfully.");
                }else{
                    Log.d("verified","OTP verified not successfully");
                }
            }
        });
    }
}

Usage (Auto verififcation OTP)

Step 1. Create one Interface class like SmsListener

public interface SmsListener {
    public void messageRceived(String messageText);
}

Step 2. Create one Broadcast receiver class like SmsReceiver

public class SmsReceiver extends BroadcastReceiver{
    private static SmsListener smsListener;
    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            Bundle data = intent.getExtras();

            Object[] pdus = (Object[]) data.get("pdus");
            for (int i = 0; i < pdus.length; i++) {
                SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
                String sender = smsMessage.getDisplayOriginatingAddress();
                if (sender != null) {
                    String messageBody = smsMessage.getMessageBody();
                    String msgLower = messageBody.toLowerCase();
                    smsListener.messageRceived(msgLower);
                }
            }
        }catch (Exception e){
            smsListener.messageRceived("something went wrong!");
        }
    }

    public static void bindListener(SmsListener listener) {
        smsListener = listener;
    }

Step 3. Bind the interface to the OTPActivity class

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

        otpEditText = (EditText) findViewById(R.id.otpEditText);
        btnVerify = (Button) findViewById(R.id.btnVerify);

        //receive the 6 digit generated OTP from previous activity
        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            otp = extras.getString("otp");
        }

        //sms receiver to auto verification
        SmsReceiver.bindListener(new SmsListener() {
            @Override
            public void messageRceived(String messageText) {
                try {
                    String sixOTPDigit = extractDigits(messageText);
                    otpEditText.setText(sixOTPDigit);
                }catch (Exception e){
                    Log.d("exception", "Something Went Wrong!");
                }
            }
        });


        //button click listener
        btnVerify.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //check the OTP verification
                if ((otp != null) && (otp.equals(otpEditText.getText().toString().trim()))) {
                    Log.d("verified","OTP verified successfully.");
                }else{
                    Log.d("verified","OTP verified not successfully");
                }
            }
        });
    }

    /**
     * extract digit from string
     * @param in
     * @return
     */
    public static String extractDigits(final String in) {
        final Pattern p = Pattern.compile( "(\\d{6})" );
        final Matcher m = p.matcher( in );
        if ( m.find() ) {
            return m.group( 0 );
        }
        return "";
    }
}

Step 4. register the broadcast receiver class in android manifest file xml

<receiver android:name=".receivers.SmsReceiver">
    <intent-filter>
      <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

Note: Add Internet persmission in android mainfest file

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