Android app cannot open web link

I have a button at the end of this application that displays the user on the default browser and on the given link. Sorry, this button is broken. I'm not sure if this is a problem with Java or with XML, but the code for both is attached.

package com.example.ldsm3;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity
import android.content.DialogInterface;
import android.content.Intent;
import android.text.SpannableString;
import android.text.method.LinkMovementMethod;
import android.text.method.MovementMethod;
import android.view.Menu;
import android.widget.Button;
import android.widget.TextView;

public class Finished extends Activity {

    public void onClick(Button button1) 
    {

        Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("URL HERE"));
        startActivity(browserIntent);
    }


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

        // tv is the ID for the TextView in the XML file
        TextView tv = (TextView) findViewById(R.id.textView2); 

        // set the TextView to show the score
        tv.setText(Misc.correct + "/" + Misc.total);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.finished, menu);
        return true;
    }

}

And the XML code ...

<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=".Finished" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="69dp"
        android:text="@string/Finished" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignRight="@+id/textView1"
        android:layout_marginBottom="19dp"
        android:text="Go to the game!" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/button1"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="93dp"
        android:text="0/0" />

</RelativeLayout>

How to fix it? Is it because of XML or Java? Did I determine the intention correctly?
