Android Network Tools \"image\"

\n

\"Android
\n\"CircleCI\"
\n

\n

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

\n\n

General info

\n

The javadoc should provide all information needed to understand the methods, but if not feel free to add a issue in github and I'll address any questions! :)

\n

Support

\n

If you love what I'm doing with Android Network Tools and my other projects, you can now support my work directly! By buying me a coffee ☕, you're not just fueling my caffeine needs – you're helping me dedicate more time to developing and improving these open source projects. Every coffee counts and brings more innovation to the cybersecurity world. Thank you for your support – it means the world to me and the open source community!

Sample app

\n

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

Usage

\n

Add as dependency

\n

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

\n

add remote maven url

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

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

\n
    dependencies {\n        compile 'com.github.stealthcopter:AndroidNetworkTools:0.4.5.3'\n    }
\n

Add permission

\n

Requires internet permission (obviously...)

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

Port Scanning

\n

A simple java based TCP / UDP port scanner, fast and easy to use. By default it will try and guess the best timeout and threads to use while scanning depending on if the address looks like localhost, local network or remote. You can override these yourself by calling setNoThreads() and setTimeoutMillis()

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

Subnet Devices

\n

Finds devices that respond to ping that are on the same subnet as the current device. You can set the timeout for the ping with setTimeOutMillis() [default 2500] and the number of threads with setNoThreads() [default 255]

\n
    // Asynchronously\n    SubnetDevices.fromLocalAddress().findDevices(new SubnetDevices.OnSubnetDeviceFound() {\n        @Override\n        public void onDeviceFound(Device device) {\n            // Stub: Found subnet device\n        }\n\n        @Override\n        public void onFinished(ArrayList<Device> devicesFound) {\n            // Stub: Finished scanning\n        }\n    });\n\n
\n

Ping

\n

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

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

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 available.

\n

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

\n

Wake-On-Lan

\n

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

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

Misc

\n

Other useful methods:

\n
      // Get a MAC Address from an IP address in the ARP Cache\n      String ipAddress = \"192.168.0.1\";\n      String macAddress = ARPInfo.getMacFromArpCache(ipAddress);
\n

Building

\n

It's a standard gradle project.
