I’m having a simple problem with starting an intent on the click of a button. Unfortunately, i can’t find a way out of this problem.

MY first activity java file is :

package com.android.SamsungMIv3;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class SamsungMIv3Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button b = (Button)findViewById(R.id.button1);
    b.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent i = new Intent(SamsungMIv3Activity.this, currentlocation.class);
            SamsungMIv3Activity.this.startActivity(i);
        }
    });
    }
}

But I’m not able to find a way to resolve this problem

 <uses-library android:name="com.google.android.maps" />
