Advanced tools
NativeScript plugin to acquire device info.
From the command prompt, go to your app's root folder and execute:
tns plugin add nativescript-dna-deviceinfo
This command automatically installs the necessary files, as well as stores nativescript-dna-deviceinfo as a dependency in your project's package.json file.
Various device related utility APIs are accessible from the DeviceInfo class. To import the class, use one of the following forms:
TypeScript:
import { DeviceInfo } from 'nativescript-dna-deviceinfo';
JavaScript:
const nativescript_dna_deviceinfo = require("nativescript-dna-deviceinfo");
const DeviceInfo = nativescript_dna_deviceinfo.DeviceInfo;
Returns total memory(RAM) size of a device in bytes.
DeviceInfo.totalMemory();
Returns free memory(RAM) size of a device in bytes.
DeviceInfo.freeMemory();
Returns total storage(internal) space of a device in bytes.
DeviceInfo.totalStorageSpace();
Returns free storage(internal) space of a device in bytes.
DeviceInfo.freeStorageSpace();
Returns a device ID.
DeviceInfo.deviceId();
Returns a device name.
DeviceInfo.deviceName();
Returns the locale of a device.
DeviceInfo.deviceLocale();
Returns the device country.
DeviceInfo.deviceCountry();
Returns the time zone of a device.
DeviceInfo.timezone();
Returns the user agent string of a device.
DeviceInfo.userAgent();
Returns an app name.
DeviceInfo.appName();
Returns an app version.
DeviceInfo.appVersion();
Returns an app bundle id.
DeviceInfo.bundleId();
Returns an app bundle number.
DeviceInfo.bundleNumber();
Returns a device manufacturer.
DeviceInfo.systemManufacturer();
Returns the charge level of a device battery.
DeviceInfo.batteryLevel();
Returns a list of GSM network providers, Carrier, of a device is equipped with.
let carriers = DeviceInfo.cellularServiceProviders();
console.log(carriers);
Below is the Carrier interface:
interface Carrier {
carrierName: string;
displayName: string;
country: string;
mobileCountryCode: string;
isoCountryCode: string;
countryCode: string;
mobileNetworkCode: string;
generation: WCTGeneration; // Wireless Cellular Technology
networkType: RadioAccessTechnology;
}
Besides other helpful information returned from the API, it can be used to know whether the device has a fast internet connection or not.
Returns a list of paths for all mountable volumes (external storage cards, USB O-T-G). The empty list means that no mountable volumes found.
DeviceInfo.externalStoragePaths();
Returns a list of StorageVolume. An empty list means that no mountable volumes found.
let storageVolumes = DeviceInfo.storageVolumes();
console.log(storageVolumes);
Below is StorageVolume interface:
interface StorageVolume {
path: string;
totalSize: number;
availableSize: number;
lowBytesLimit: number;
fullBytesLimit: number;
description: string;
isRemovableStorage: boolean;
isAllowMassStorage: boolean;
isEmulated: boolean;
isPrimary: boolean;
}
Returns service set identifier(SSID) of a wireless local area network (WLAN). In the absence of right permissions, returns an empty string.
DeviceInfo.wifiSSID();
