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.

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"/>

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.
