Retrieve system properties using System.getProperties()

getProperties() method of java.lang.System returns the system properties. Here is a example to retrieve system properties using System.getProperties().

package com.blogspot.android_er.androidsystemproperties;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

import java.util.Enumeration;
import java.util.Properties;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView info = (TextView)findViewById(R.id.info);

        Properties properties = System.getProperties();
        info.append(properties.toString());
        info.append("\n----------\n\n");

        Enumeration<String> prop =
                (Enumeration<String>) properties.propertyNames();

        while(prop.hasMoreElements()){
            String propName = prop.nextElement();
            info.append(propName + " : \n" +
                    System.getProperty(propName) + "\n\n");

        }
    }

}
