IMEI, also known as International mobile equipment identity, is a unique number that every mobile in the world has. It is usually used to manage and identify phones. Unfortunately, the correct process of finding IMEI programmatically is very less discussed.

As a result, many of us find it hard to get IMEI on android. So this guide is all about learning a few different ways of getting it manually with step-by-step guide.

Step by Step Guide on How to Get IMEI in Android Programmatically:

So for the first way, we are going to be using TelephonyManager. It provides access to information about the telephony services on the device. There are two ways of getting IMEI using TelephonyManager and we will be discussing both.

So let’s get straight into it:

Step-1:

Call android.telephony.TelephonyManager.getDeviceId().

It would look into its database and return whichever unique numbers identify the device. It usually is IMEI for GSM and MEID for CDM.

Step2:

You need to use the following permission in your AndroidManifest.xml:

<uses-permission android:name=”android.permission.READ_PHONE_STATE” />

This has to be done if you want this process to work.

Step3:

You should also add the following code in your AndroidManifest.xml

<uses-permission android:name=”android.permission.READ_PHONE_STATE”/>

We recommend adding this because in the emulator, you might get a value like “0000….”. As getDeviceId() returns null if the device Id is not available.

Moreover, you can also use the following code to get IMEI on your android device programmatically.

Step1:

Enter the code given below:

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

String device_id = tm.getDeviceId();

Step2:

Add the following permission in Android Manifest:

android.permission.READ_PHONE_STATE

This is more like the way easier way of getting your IMEI without having to ask anyone or pay anyone to do it.

So, for the second way, we are going to be working with Android Studio. In a nutshell, it is an android device’s official IDE. The main objective for android studio is to accelerate your development and aid you in building a good quality app. Today we are going to be using it to get our android device’s IMEI.

Follow the steps given below:

Step1:

Start android studio and create a new project. For that go to Files⇒ New project and fill in all the required details to create a new project.

Step2:

Add the following code to res/layout/activity_main.xml.

<?xml version=”1.0″ encoding=”utf-8″?>

<RelativeLayout 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”

   tools:context=”.MainActivity”>

   <Button

      android:id=”@+id/button”

      android:text=”Check IEMI number”

      android:layout_width=”wrap_content”

      android:layout_height=”wrap_content”

      android:layout_centerInParent=”true”

      android:layout_above=”@id/textView”

      android:layout_marginBottom=”20sp”/>

   <TextView

      android:id=”@+id/textView”

      android:textSize=”16sp”

      android:hint=”Your IEMI number”

      android:layout_width=”wrap_content”

      android:layout_height=”wrap_content”

      android:layout_centerInParent=”true”/>

  </RelativeLayout>

Step3:

So, for the next step, we are going to add the following code to src/MainActivity.java

import android.Manifest;

import android.content.Context;

import android.content.pm.PackageManager;

import android.support.annotation.NonNull;

import android.support.v4.app.ActivityCompat;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.telephony.TelephonyManager;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

   Button button;

   TextView textView;

   String IMEINumber;

   private static final int REQUEST_CODE = 101;

   @Override

   protected void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.activity_main);

      textView = findViewById(R.id.textView);

      button = findViewById(R.id.button);

      button.setOnClickListener(new View.OnClickListener() {

         @Override

         public void onClick(View v) {

            TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

            if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {

               ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CODE);

               return;

            }

            IMEINumber = telephonyManager.getDeviceId();

            textView.setText(IMEINumber);

         }

      });

   }

   @Override

   public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {

      switch (requestCode) {

         case REQUEST_CODE: {

            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

               Toast.makeText(this, “Permission granted.”, Toast.LENGTH_SHORT).show();

            } else {

               Toast.makeText(this, “Permission denied.”, Toast.LENGTH_SHORT).show();

            }

         }

      }

   }

Step4:

Then lastly, we are going to add this to androidManifest.xml

<manifest xmlns:android=”http://schemas.android.com/apk/res/android” package=”app.com.sample”>

   <uses-permission android:name=”android.permission.READ_PHONE_STATE” />

   <application

      android:allowBackup=”true”

      android:icon=”@mipmap/ic_launcher”

      android:label=”@string/app_name”

      android:roundIcon=”@mipmap/ic_launcher_round”

      android:supportsRtl=”true”

      android:theme=”@style/AppTheme”>

      <activity android:name=”.MainActivity”>

         <intent-filter>

            <action android:name=”android.intent.action.MAIN” />

            <category android:name=”android.intent.category.LAUNCHER” />

         </intent-filter>

      </activity>

   </application>

</manifest>

By doing this, we have created an application that will help us get our IMEI. Hopefully, you have connected your actual mobile device with your computer. As for running this, start the app from android studio, open one of your project’s activity files and click the “Run” icon from the toolbar.

Select your mobile device as an option and then check your display. What you should be seeing is:
