Android Arsenal

Disapointed by the lack of good network apis in android / java I developed a collection of handy networking tools for everyday android development.

• Ping
• Port Scanning
• Subnet tools (find devices on local network)
• Wake-On-Lan
• & More :)

The sample app is published on Google play to allow you to quickly and easier test the library. Enjoy! And please do feedback to us if your tests produce different results.

This library is not yet released in Maven Central, until then you can add as a library module or use JitPack.io

add remote maven url

 repositories {
 maven {
 url "https://jitpack.io"
 }
 }

then add a library dependency. Remember to check for latest release here

 dependencies {
 compile 'com.github.stealthcopter:AndroidNetworkTools:0.1.1'
 }

Requires internet permission (obviously...)

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

Uses the native ping binary if avaliable on the device (some devices come without it) and falls back to a TCP request on port 7 (echo request) if not.

 // Synchronously 
 PingResult pingResult = Ping.onAddress("192.168.0.1").setTimeOutMillis(1000).doPing();
 
 // Asynchronously
 Ping.onAddress("192.168.0.1").setTimeOutMillis(1000).setTimes(5).doPing(new Ping.PingListener() {
 @Override
 public void onResult(PingResult pingResult) {
 ...
 }
 });

Note: If we do have to fall back to using TCP port 7 (the java way) to detect devices we will find significantly less than with the native ping binary. If this is an issue you could consider adding a ping binary to your application or device so that it is always avaliable.

A simple java based TCP port scanner, fast and easy to use.

 // Synchronously 
 ArrayList<Integer> openPorts = PortScan.onAddress("192.168.0.1").setPort(21).doScan();
 
 // Asynchronously
 PortScan.onAddress("192.168.0.1").setTimeOutMillis(1000).setPortsAll().doScan(new PortScan.PortListener() {
 @Override
 public void onResult(int portNo, boolean open) {
 if (open) // Stub: found open port
 }
 @Override
 public void onFinished(ArrayList<Integer> openPorts) {
	// Stub: finished scanning
 }
 });

Note: If you want a more advanced portscanner you should consider compiling nmap into your project and using that instead.

Sends a Wake-on-Lan packet to the IP / MAC address

 String ipAddress = "192.168.0.1";
 String macAddress = "01:23:45:67:89:ab";
 WakeOnLan.sendWakeOnLan(ipAddress, macAddress);

Other useful methods:

 String ipAddress = "192.168.0.1";
 String macAddress = ARPInfo.getMacFromArpCache(ipAddress);

It's a standard gradle project.
