Read Android system info., using System.getProperty

It's another exercise to read Android system information, using system provided method getProperty.



Create a new Android Application, with the Activity named AndroidSYSinfoActivity. Modify the main.xml and AndroidSYSinfoActivity.java:
main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 >
<TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:gravity="center_horizontal"
 android:text="android-er.blogspot.com"
 android:autoLink="web"
 />
<TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="Android System:"
 />
<TextView
 android:id="@+id/SYSinfo"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 />
</LinearLayout>

Download main.xml.
