Does anybody know how to get the serial number of a device?

I know I can do this in a NativeScript-5 application (TypeScript):

import { Page } from "tns-core-modules/ui/page";    
import * as platformModule from "tns-core-modules/platform";

export function onNavigatingTo(args: EventData) {
    let page = <Page>args.object;

    console.log("Manufacturer:" + platformModule.device.manufacturer);
    console.log("Model:" + platformModule.device.model);
    console.log("UUID:" + platformModule.device.uuid);
}

But I couldnt find any property for the device's serial number. Anybody an idea? It's alright if your solution only covers Android (since my project is targeting Android tablets only).

Thanks!

Update:

Manoj pointed me to some Java code that probably solves my problem. However, I wasn't able to marshal the following code to TypeScript. 

      public static String getManufacturerSerialNumber() { 
          String serial = null; 
          try {
               Class<?> c = Class.forName("android.os.SystemProperties");
               Method get = c.getMethod("get", String.class, String.class);
               serial = (String) get.invoke(c, "ril.serialnumber", "unknown");
          } catch (Exception ignored) {}
          return serial;
      }

Maybe anybody could help me? That would be awesome!

iOS never allows any confidential information to be accessed by apps, that applies to serial number too. With Android, you may read the serial number with

android.os.Build.SERIAL

I had it tested with Playground

Edit 1:

Manufactures like Samsung seems to have a different serial number which is not same as android.os.Build.SERIAL. Here is another SO thread that seems very relevant for Samsung, the sample code is written in Java.

Edit 2:

Here is how you may get serial number on Samsung devices

        let serialNumber = ''; 
        try {
            const cl = application.android.context.getClassLoader();
            const SystemProperties = cl.loadClass('android.os.SystemProperties');

            const paramTypes = (<any>Array).create(java.lang.Class, 2);
            paramTypes[0] = java.lang.String.class;
            paramTypes[1] = java.lang.String.class;
            const getMethod = SystemProperties.getMethod('get', paramTypes);

            const params = (<any>Array).create(java.lang.Object, 2);
            params[0] = new java.lang.String('ril.serialnumber');
            params[1] = new java.lang.String('unknown');

            serialNumber = getMethod.invoke(SystemProperties, params);
        } catch (err) {
            console.error(err);
        }

  • Hello Manoj, amazing how many IDs a device has. On my Samsung Galaxy Tablet your code returns "330050c2712865fb" which is actually the ID that NativeScript's CLI displays when I do "tns run". Except, this still is not the serial number I am looking for. On my tablet, when I go into "Settings > About tablet" I can see a "Serial number: R52K90L6TZH". This is also the number which is printed on the box and a sticker on the device. It's also the number that Samsung Knox uses for MDM. Weird, so many numbers ... – Ingmar Dec 21 '18 at 18:58
  • Samsung / MI brands do customise the Android for their device. As per the official android documentation, this is the API we should use and it works on my Moto G5+ which is a true (untouched) Android from Google. I will still take a look if I find anything on Samsung. – Manoj Dec 21 '18 at 19:01
  • Thank you so much, Manoj. I also keep on researching ... if you find a solution for Samsung that's good enough for my purposes. – Ingmar Dec 21 '18 at 19:05
  • I have updated the answer with a link to other SO thread that has multiple solutions for Samsnug, except it's written in Java. I hope you may able to marshall that into JS / TS. – Manoj Dec 21 '18 at 19:08
  • Not sure. Will have a look at this on the weekend ;) Thanks for now, Manoj. – Ingmar Dec 21 '18 at 19:09
  • Let me know in case if you find it hard. I will have to find my old Samsung Tablet if I have to test this. – Manoj Dec 21 '18 at 19:12
  • Damn. Wasn't able to solve this one. Tried to access "android.os.SystemProperties" by following https://docs.nativescript.org/core-concepts/android-runtime/metadata/accessing-packages#access-android-classes, but ended up ... nowhere. – Ingmar Dec 22 '18 at 16:31

You can check properties 'ro.serialno', 'ril.serialnumber', 'gsm.sn1', 'sys.serialnumber'

Android: How to programmatically access the device serial number shown in the AVD manager (API Version 8)

In my case Samsung TAB S2 has 2 serials. Property 'ro.serialno' more accurate then 'ril.serialnumber'. So i check it first.

getSerial() {
  if (isAndroid) {
    let serialNumber = null;
    try {
      const cl = application.android.context.getClassLoader();
      const SystemProperties = cl.loadClass('android.os.SystemProperties');

      const paramTypes = (<any>Array).create(java.lang.Class, 2);
      paramTypes[0] = java.lang.String.class;
      paramTypes[1] = java.lang.String.class;
      const getMethod = SystemProperties.getMethod('get', paramTypes);

      const params = (<any>Array).create(java.lang.Object, 2);

      // Reorder if needed
      const props = ['ro.serialno', 'ril.serialnumber', 'gsm.sn1', 'sys.serialnumber'];

      for(let i = 0, len = props.length; i < len; i++) {

        params[0] = new java.lang.String(props[i]);
        serialNumber = getMethod.invoke(SystemProperties, params);

        if (serialNumber !== '') {
          return serialNumber;
        }
      }

    } catch (err) {
      console.error(err);
    }

    return serialNumber;
  }
}
