Here is the Main.java

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;

public class Main extends TabActivity {

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    TabHost tabHost = getTabHost();
    tabHost.addTab(tabHost.newTabSpec("one").setIndicator("Rated Calls")
            .setContent(new Intent(this, RatedCalls.class)));
    tabHost.addTab(tabHost.newTabSpec("two").setIndicator("Rated Contacts")
            .setContent(new Intent(this, SMS.class)));

    tabHost.setCurrentTab(2);

}

    }

Here is the RatedCalls.java class

import java.text.DateFormat;
import java.util.ArrayList;

import com.psyhclo.R;

import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;

public class RatedCalls extends Activity {

private static TextView txtView;
private CallDataHelper dh;
StringBuilder sb = new StringBuilder();

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.ratedcalls);        

    //txtView = (TextView) findViewById(R.id.TextView01);
    TextView txtView = new TextView(this);
    Cursor cursor = getContentResolver().query(
            android.provider.CallLog.Calls.CONTENT_URI, null, null, null,
            android.provider.CallLog.Calls.DATE + " DESC ");

    startManagingCursor(cursor);
    int numberColumnId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.NUMBER);
    int durationId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.DURATION);
    int contactNameId = cursor
            .getColumnIndex(android.provider.CallLog.Calls.CACHED_NAME);
    int dateId = cursor.getColumnIndex(android.provider.CallLog.Calls.DATE);
    int numTypeId = cursor.getColumnIndex(android.provider.CallLog.Calls.CACHED_NUMBER_TYPE);

    ArrayList<String> callList = new ArrayList<String>();
    if (cursor.moveToFirst()) {
        do {

            String callerPhoneNumber = cursor.getString(numberColumnId);
            String contactName = cursor.getString(contactNameId);
            String duration = cursor.getString(durationId);
            String callDate = DateFormat.getDateInstance().format(dateId);      
            String numType = cursor.getString(numTypeId);

            //this.dh.insert(1, contactName, callerPhoneNumber, numType, duration, callDate, "01:20");
            Toast.makeText(getBaseContext(), "Inserted!", Toast.LENGTH_LONG);
            callList.add("\nNew Info: \nContact Number: "
                    + callerPhoneNumber + "\nContact Name: " + contactName
                    + "\nDuration: " + duration + "\nDate: " + callDate);

        } while (cursor.moveToNext());
    }
    txtView.setText(callList.toString());
}
    }

And here is the ratedcalls.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"

    android:padding="5dp">
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp" />
</LinearLayout>
</TabHost>

And here is the main.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"

        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <FrameLayout
        android:id="@android:id/tabcontent"

The log clearly states the problem:

SecurityException: Permission Denial: opening provider
com.android.providers.contacts.CallLogProvider requires
android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS

Check your permissions in your manifest file.
