  • Your if condition is wrong try this `if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){deviceImei = telephonyManager.getImei();}else{deviceImei =telephonyMgr.getDeviceId();}` – Sunil Sunny May 30 '18 at 07:21

Starting from android 8 you need to use getImei(int slotIndex) to retrieve the IMEI of the device.

You also need to add <uses-permission android:name="android.permission.READ_PHONE_STATE"/> permission in your AndroidManifest.xml

Remember to implement permission model to request permission at runtime as follows:

ActivityCompat.requestPermissions(MainActivity.this,
                    new String[]{Manifest.permission.READ_PHONE_STATE},
                    1);
@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case 1: {

          // If request is cancelled, the result arrays are empty.
          if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

               //continue using `getImei()` or `getDeviceId()`  
            } else {

               //Use device Id or use fallback case
            }
            return;
        }   
    }
}
