Question

I have a HTML5 webpage, I want to use webview for Android DSK.

This is my androidmanifest.xml

 <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.example.myfirstapp"
 android:versionCode="1"
 android:versionName="1.0" >

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

 <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.myfirstapp.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
 </application>

 </manifest>

And this is my activitymain.xml on the layout folder:

 <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"
 tools:context=".MainActivity" >

 <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@string/hello_world" />


<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>

</RelativeLayout>

What else should I do? And where to put that code?

Google android documentation says this:

To load a web page in the WebView, use loadUrl(). For example:

WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("http://www.example.com");

But where should I put these lines of code? In a new file? I’ve tried a lot of things with no success.

Call this from your MainActivity.java file:

package com.example.myfirstapp;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

    public class MainActivity extends Activity {

        private WebView webView;

        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activitymain);

            webView = (WebView) findViewById(R.id.webview);
            webView.getSettings().setJavaScriptEnabled(true);
            webView.loadUrl("http://www.google.com");

        }

    }

Here is a good reference with example:
