Answer 1

Id was mismatching

Change your layout like this

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.luke.sinhalasindu.Ruwan_Hettiaracchi" >

    <WebView
        android:id="@+id/webView"
        android:layout_width="400dp"
        android:layout_height="200dp" />

</RelativeLayout>

In java initialize WebView variable like this

WebView view = (WebView) findViewById(R.id.webView);

Answer 2

From your layout

WebView view = (WebView) this.findViewById(R.id.webView);

should be

WebView view = (WebView) this.findViewById(R.id.webView1);

Answer 3

add android:id="@+id/webView" on activity_main.xml
