SMS verification is very easy and more user friendly than email verification. Now a days where most of app have a registration form, we need to confirm the user information is accurate and user enter valid phone no. In this i explain you how we can create simple sms verification in android application.
Step 1. Before we start create application we need a standard msg to read a verification from message eg.
Your application VPN is : 12345
Step 2. Now create new android project in your Android Studio/ Eclipse.
Step 3. Open your activity_main.xml file inside res -> layout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:orientation="vertical"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<TextView
android:id="@+id/msg"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<EditText
android:id="@+id/gd"
android:textSize="22dp"
android:hint="----"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Step 4. Now open your MainActivity.java and add this code.
package com.readlastsms;
import android.database.Cursor;
import android.database.sqlite.SQLiteException;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.widget.EditText;
import android.widget.TextView;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MainActivity extends ActionBarActivity {
TextView txt;
EditText text;
Handler handler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt = (TextView) findViewById(R.id.msg);
text = (EditText) findViewById(R.id.gd);
handler.postDelayed(run, 1000);
}
Runnable run = new Runnable() {
@Override
public void run() {
getCode();
}
};
public void getCode() {
StringBuilder smsBuilder = new StringBuilder();
final String SMS_URI_INBOX = "content://sms/inbox";
final String SMS_URI_ALL = "content://sms/";
try {
Uri uri = Uri.parse(SMS_URI_INBOX);
String[] projection = new String[]{"_id", "address", "person", "body", "date", "type"};
Cursor cur = getContentResolver().query(uri, projection, "address LIKE '%MyTsky'", null, "date desc limit 1");
if (cur.moveToFirst()) {
int index_Address = cur.getColumnIndex("address");
int index_Person = cur.getColumnIndex("person");
int index_Body = cur.getColumnIndex("body");
int index_Date = cur.getColumnIndex("date");
int index_Type = cur.getColumnIndex("type");
do {
String strAddress = cur.getString(index_Address);
int intPerson = cur.getInt(index_Person);
String strbody = cur.getString(index_Body);
long longDate = cur.getLong(index_Date);
int int_Type = cur.getInt(index_Type);
smsBuilder.append("[ ");
smsBuilder.append(strAddress + ", ");
smsBuilder.append(intPerson + ", ");
smsBuilder.append(strbody + ", ");
smsBuilder.append(longDate + ", ");
smsBuilder.append(int_Type);
smsBuilder.append(" ]\n\n");
String str = strbody;
Pattern pattern = Pattern.compile("\\w+([0-9])");
Matcher matcher = pattern.matcher(str);
for (int i = 0; i < matcher.groupCount(); i++) {
matcher.find();
Log.e("No....--", matcher.group());
if (matcher.group().equals("")) {
handler.postDelayed(run, 7000);
} else {
text.setText(matcher.group());
}
}
} while (cur.moveToNext());
if (!cur.isClosed()) {
cur.close();
cur = null;
}
} else {
smsBuilder.append("no result!");
} // end if
Log.e("sms", smsBuilder.toString());
txt.setText(smsBuilder.toString());
} catch (SQLiteException ex) {
Log.d("SQLiteException", ex.getMessage());
}
}
}
Here in our mainactivty.java i create a method getCode() in this method i query default database of android to read message for specific no. To read about getContentResolver().query() follow this link.
String[] projection = new String[]{"_id", "address", "person", "body", "date", "type"};
Cursor cur = getContentResolver().query(uri, projection, "address LIKE '%MyTsky'", null, "date desc limit 1");
I read message for specific no to get OTP code.
public void getCode() {
StringBuilder smsBuilder = new StringBuilder();
final String SMS_URI_INBOX = "content://sms/inbox";
final String SMS_URI_ALL = "content://sms/";
try {
Uri uri = Uri.parse(SMS_URI_INBOX);
String[] projection = new String[]{"_id", "address", "person", "body", "date", "type"};
Cursor cur = getContentResolver().query(uri, projection, "address LIKE '%MyTsky'", null, "date desc limit 1");
if (cur.moveToFirst()) {
int index_Address = cur.getColumnIndex("address");
int index_Person = cur.getColumnIndex("person");
int index_Body = cur.getColumnIndex("body");
int index_Date = cur.getColumnIndex("date");
int index_Type = cur.getColumnIndex("type");
do {
String strAddress = cur.getString(index_Address);
int intPerson = cur.getInt(index_Person);
String strbody = cur.getString(index_Body);
long longDate = cur.getLong(index_Date);
int int_Type = cur.getInt(index_Type);
smsBuilder.append("[ ");
smsBuilder.append(strAddress + ", ");
smsBuilder.append(intPerson + ", ");
smsBuilder.append(strbody + ", ");
smsBuilder.append(longDate + ", ");
smsBuilder.append(int_Type);
smsBuilder.append(" ]\n\n");
String str = strbody;
Pattern pattern = Pattern.compile("\\w+([0-9])");
Matcher matcher = pattern.matcher(str);
for (int i = 0; i < matcher.groupCount(); i++) {
matcher.find();
Log.e("No....--", matcher.group());
if (matcher.group().equals("")) {
handler.postDelayed(run, 7000);
} else {
text.setText(matcher.group());
}
}
} while (cur.moveToNext());
if (!cur.isClosed()) {
cur.close();
cur = null;
}
} else {
smsBuilder.append("no result!");
} // end if
Log.e("sms", smsBuilder.toString());
txt.setText(smsBuilder.toString());
} catch (SQLiteException ex) {
Log.d("SQLiteException", ex.getMessage());
}
}
Here i also use handler to check if new message is arrive and read OTP code from the message. This is a simple code to extract OTP from message
String str = strbody;
Pattern pattern = Pattern.compile("\\w+([0-9])");
Matcher matcher = pattern.matcher(str);
for (int i = 0; i < matcher.groupCount(); i++) {
matcher.find();
Log.e("No....--", matcher.group());
if (matcher.group().equals("")) {
handler.postDelayed(run, 7000);
} else {
text.setText(matcher.group());
}
}
Hope this help you some where. Thanku! 🙂
