您应该在 AndroidManifest.xml 中拥有 ACCESS_WIFI_STATE 权限以捕获 IP 地址.

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

那么你所要做的就是，

import * as application from 'tns-core-modules/application';声明var android;const wifiManager = application.android.context.getSystemService(android.content.Context.WIFI_SERVICE);const connectionInfo = wifiManager.getConnectionInfo();const ip = android.text.format.Formatter.formatIpAddress(connectionInfo.getIpAddress());

declare var android; 是为了避免访问原生api时出现TS错误.另一种方法是安装 tns-platform-declarations 插件并将声明文件指向 references.d.ts.

关于 Mac 地址，因为 Android6.0

为了向用户提供更好的数据保护，从本版本开始，Android 移除了使用 Wi-Fi 和蓝牙 API 的应用对设备本地硬件标识符的编程访问.WifiInfo.getMacAddress() 和 BluetoothAdapter.getAddress() 方法现在返回一个常量值 02:00:00:00:00:00.

所以它似乎没有得到官方支持.

I want to get IP address from my mobile Android.

var context = application.android.context;
var wifiMgr = context.getSystemService("wifi");
var wifiInfo = wifiMgr.getConnectionInfo();
var ip = wifiInfo.getIpAddress();
console.log('ip', ip)

The result is: JS: ip -2029999936

But in fact this is not my IP.

Can you ask me any idea?

Update:

I follow this . I have this code:

Step1. In my component add this code:

import app = require("application");
app.android.context;
      constructor() {
      var context = android.content.Context;
      var wifiManager = app.android.context.getSystemService(context.WIFI_SERVICE);
      var wInfo = wifiManager.getConnectionInfo();
      var mac = wInfo.getMacAddress();
        }

Step2. In AndroidManifest.xml add

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> 

Error: [ts] Cannot find name 'android'. [2304] in this line: var context = android.content.Context; error TS1202: Import assignment cannot be used when targeting ECMAScript modules. Consider using 'import * as ns from "mod"', 'import {a} from "mod"', 'import d from "mod"', or another module format instead.

You should have ACCESS_WIFI_STATE permission in AndroidManifest.xml for capturing IP address.

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Then all you have to is,

import * as application from 'tns-core-modules/application';
declare var android;

const wifiManager = application.android.context.getSystemService(android.content.Context.WIFI_SERVICE);
const connectionInfo = wifiManager.getConnectionInfo();
const ip = android.text.format.Formatter.formatIpAddress(connectionInfo.getIpAddress());

declare var android; is to avoid TS errors while access native apis. An alternative is to install tns-platform-declarations plugin and point the declaration files in your references.d.ts.

Regarding the Mac Address, since Android 6.0

To provide users with greater data protection, starting in this release, Android removes programmatic access to the device’s local hardware identifier for apps using the Wi-Fi and Bluetooth APIs. The WifiInfo.getMacAddress() and the BluetoothAdapter.getAddress() methods now return a constant value of 02:00:00:00:00:00.

So it doesn't seem officially supported.
