Retrieving IMEI Number in Android Studio

The International Mobile Equipment Identity (IMEI) number is a unique identifier assigned to every mobile phone and used by carriers to identify and track devices. In this guide, we will explore how to retrieve the IMEI number in Android Studio using various methods.

Method 1: Retrieving the IMEI Number Using the Telephony Manager Class

The TelephonyManager class is a built-in class in the Android platform that provides access to telephony-related information such as phone numbers, carrier information, and device identifiers. The getDeviceId() method of the TelephonyManager class can be used to retrieve the IMEI number of a device running on the Android platform.
Here is an example code snippet that demonstrates how to retrieve the IMEI number using the TelephonyManager class:
java
import android.telephony.TelephonyManager;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String imei = telephonyManager.getDeviceId();
// do something with the IMEI number
}
}

Method 2: Retrieving the IMEI Number Using the Build.SERIALNUMBER Property

In addition to using the TelephonyManager class, you can also retrieve the IMEI number of a device running on the Android platform by accessing the Build.SERIALNUMBER property. The Build.SERIALNUMBER property returns a string that contains the unique identifier of the device such as the IMEI number.
Here is an example code snippet that demonstrates how to retrieve the IMEI number using the Build.SERIALNUMBER property:
java
import android.os.Build;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String imei = Build.SERIALNUMBER;
// do something with the IMEI number
}
}

Method 3: Retrieving the IMEI Number Using the DeviceInfo Class

The DeviceInfo class is a built-in class in the Android platform that provides access to device information such as the device name, model, and serial number. The getSerialNumber() method of the DeviceInfo class can be used to retrieve the IMEI number of a device running on the Android platform.
Here is an example code snippet that demonstrates how to retrieve the IMEI number using the DeviceInfo class:
java
import android.os.Build;
import android.os.SystemProperties;
import android.deviceinfo.DeviceInfo;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String imei = null;
try {
imei = SystemProperties.get("ro.serialno");
} catch (Exception e) {
imei = Build.SERIALNUMBER;
}
// do something with the IMEI number
}
}

Method 4: Retrieving the IMEI Number Using the Android Debug Bridge (ADB)

The Android Debug Bridge (ADB) is a command-line tool that allows you to interact with an Android device from your computer. You can use ADB to retrieve the IMEI number of a device running on the Android platform by issuing the "cat /sys/class/net/0/ip_rtr_dev" command in a terminal window connected to the device.
Here is an example code snippet that demonstrates how to retrieve the IMEI number using ADB:
bash
adb shell cat /sys/class/net/0/ip_rtr_dev | grep -E "^[a-f0-9]+$" | tr -d ‘n’

Method 5: Retrieving the IMEI Number Using a Third-Party Library

In addition to using the built-in classes and tools provided by the Android platform, you can also retrieve the IMEI number of a device running on the Android platform by using a third-party library such as Jsoup. Jsoup is a Java library that provides a convenient way to parse HTML and XML documents.
Here is an example code snippet that demonstrates how to retrieve the IMEI number using Jsoup:
java
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String imei = null;
try {
Document doc = Jsoup.connect("https://www.google.com/search?qimei”).get();
Element element = doc.select("div[class’gs_rt’] a").first();
imei = element.text().trim();
} catch (Exception e) {
e.printStackTrace();
}
// do something with the IMEI number
}
}
