I am writing this tutorial as lot of people are asking me about how to get System properties like what is the version,Model,Hardware Manufacturer,Serial and FingerPrint of a device.As well as many of the visitors also request me to post on how to get ip4/ip6 and MAC Address of Device.
So Today I am creating a simple ListView to show all the list of system properties i mentioned above and a Utility class that will return an Array list of strings to load listView adapter.
OutPut:
Create new Android Project
Project Name: DeviceInformation
//tested from 2.3.3 to current android sdk
Build Target: Android 2.3.3 //or greater than that
Application Name: DeviceInformation
Package Name: com.shaikhhamadali.blogspot.deviceinformation
Create Layout file: activity_device_info
1. code of Layout:
1. code of Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

<ListView

</RelativeLayout>
2. code of activity:

import android.widget.ListView;
public class DeviceInfo extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_device_info);
//Create instance of Listview and assign reference of control we declared in layout
ListView lv=(ListView)findViewById(R.id.listView1);
//create an instance of ArrayAdapter and pass context,layout,list of items
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
Utility.getlist() );
//assign adapter to listview
lv.setAdapter(arrayAdapter);
}
}

return buf.toString();
}
} catch (Exception ex) { } // for now ignore exceptions
return "";

int delim = sAddr.indexOf('%'); // drop ip6 port suffix
//return ipv6
return delim<0 ? sAddr : sAddr.substring(0, delim);

}

} catch (Exception ex) { } // for now ignore Exceptions
return "";
}
}
3. note that:
-
As I ignored exceptions above but Good practice is to always check that or notify that to users regarding the problem.
- Above I have used NetworkInterface that represent a network interface of the local device. An interface is defined by its address and a platform dependent name. The class provides methods to get all information about the available interfaces of the system or to identify the local interface of a joined multicast group.
- Also InetAddress used to get the IPV4 or IPV6 of a device.
- You may be interested in getting paired devices list, get list of sensors, ListView from array and array strings.

4. conclusion:
- Some information about how to device information.
- Some information about how to get IP and MAC address.
- know how to create an Array Adapter.
- Know how to us NetworkInterface class and InetAddress class.
- Some information about how to device information.
- Some information about how to get IP and MAC address.
