In Android how to make my activity behave like a browser

Question

I have two activities "Main" (with a button in it) & "Second", and I want when I click on the button in Main activity then Second activity should be launched but it should behave like a browser. Means browser should be opened when Second activity is launched.

My code is as follow:
In manifest file I have written

    <activity android:name=".Second">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.BROWSABLE"/>
        </intent-filter>
    </activity>

In Main.java file I have written event handler like this

Button b = (Button) findViewById(R.id.button1);

b.setOnClickListener(new OnClickListener() {

         @Override
         public void onClick(View v) {
         // TODO Auto-generated method stub

         Intent intent = new Intent(Main.this, Second.class);
         startActivity(intent);
    }
});

First of all, is it possible what I want and if yes then am I doing it in right way? And really sorry if I my question is stupid, because I am new to Android

write this in your Second activity. As your second activity will call it will open a browser.

You can also use this in onClick() also.

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")));

When I started learning about android and its intents I found it very confusing. But category BROWSABLE in the Manifest does the following.

The target activity can be safely invoked by the browser to display data referenced by a link — for example, an image or an e-mail message.

Read more on: http://developer.android.com/guide/components/intents-filters.html

The two other answers opens the standard web browser and goes to the address specified. If you want a custom browser make the second activity like a web view like this example:

Good luck!

Seems like you are trying to open a browser to a specific page when the button is clicked on the Main acitvity.

If that is the case you don't need the Second activity, you just need to do something like this:

Button b = (Button) findViewById(R.id.button1);

b.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
        startActivity(i);
    }
}
