Ionic native device plugin @ionic-native/device returns all nulls

I need to do a device detection in my Ionic project so I've installed @ionic-native/device plugin per instructions here: https://ionicframework.com/docs/native/device/

However when I wire it in inside of a component, then run ionic serve to preview changes, console.log returns Device object with all values set to null, same happens when I try to use individual property e.g. this.device.model: console.log output

Here is how I use it inside of a component:

import {Device} from "@ionic-native/device";
// ...

@Component({
    // ...
})
export class MyComponent {

    constructor(private device: Device) {
    }

    ngOnInit() {
        console.log(this.device);
    }

}

And I've added it to AppModule as well:

import {Device} from "@ionic-native/device";
// ...

@NgModule({
    // ...
    providers: [
        Device
    ]
})
export class AppModule() {
}

Cordova device plugin was auto injected into config.xml:

<?xml version='1.0' encoding='utf-8'?>
<widget <!-- ... --> >
    <!-- ... -->
    <plugin name="cordova-plugin-device" spec="2.0.0" />
</widget>

Here is my Ionic stack (at least packages that should be relevant to the issue):

"@angular/*": "^5.2.4",      // all packages
"@ionic-native/*": "4.5.2",  // all packages

"@ionic-native/device": "4.5.2"
"ionic-angular": "3.9.2",
"cordova-plugin-device": "2.0.0",
"typescript": "2.6.2"

Thanks!

UPDATE:

I was able to get device details in the browser by running:

cordova run browser

This assumes you have added browser as a platform, if not run:

ionic cordova platform add browser

(From the link in the answer posted by @AndrewLively: https://stackoverflow.com/a/49034015/448816)

Solution

  • If you are running in the browser using ionic serve then most of the ionic-native plugins won't work since it is not treated by ionic as a valid browser platform.

    This is not well documented, but is discussed in an issue in the ionic-native repo.
