Android WiFi Tools

Android library for finding connected devices on the same WiFi network. It can provide IP Addresses, device names, MAC Address and vendor names.

Alternative [Use this instead]

https://github.com/tejmagar/AndroidNetworkTools use this instead.

Usage

Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Add the dependency

dependencies {
    implementation 'com.github.tejmagar:AndroidWiFiTools:1.0.2'
}

Add Permission

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

Update build.gradle(:app) for Android 11

android {
    ...
    defaultConfig {
        ...
        //noinspection OldTargetApi
        targetSdkVersion 29
        ...
        }
}

Find Connected Devices

 DevicesFinder devicesFinder = new DevicesFinder(this, new OnDeviceFindListener() {
            @Override
            public void onStart() {

            }

            @Override
            public void onDeviceFound(DeviceItem deviceItem) {
                
            }

            @Override
            public void onComplete(List<DeviceItem> deviceItems) {

            }

            @Override
            public void onFailed(int errorCode) {

            }
        });
        
devicesFinder.start();

Set Timeout

Increasing timeout value may give you better results.

devicesFinder.setTimeout(5000).start();

Get Mac Address from IP Address

String macAddress = MacAddressInfo.getMacAddressFromIp("192.168.1.1");

Before running this code, make sure you have already run deviceFinder.start(); method.

Returns device Mac Address. If not found, it will return "unknown" or Constants.UNKOWN

Get current device IP Address

String ipAddress = devicesFinder.getCurrentDeviceIpAddress();
// or
String ipAddress = Utils.getCurrentDeviceIpAddress();

Get current device Mac Address

String currentDeviceIpAddress = devicesFinder.getCurrentDeviceIpAddress();
String currentDeviceMacAddress = MacAddressInfo.getCurrentDeviceMacAddress(currentDeviceIpAddress);

Get vendor name from Mac Address

String vendorName = VendorInfo.getVendorName("94:17:00:3a:f9:09");

returns device Mac Address. If not found, it will return "unknown" or Constants.UNKNOWN

VendorInfo.init(context); will be automatically called while starting the device finder. If not, make sure you have initialized it first.
