Table Layout in Tab Layout in Android

I've got a problem in Android. I'm quite new in this thing so please don't treat me so hard. So my problem is i wanna integrate a table layout in a tab layout. I wrote the code and the IDE doesn't show any problems, it install it to the emulator with no problem, but when i wanna run the application it gives me an error(unfortunately, applicaton name has stopped). And that's it. I link some code here. I thanks forward your helps.

package hu.EasyBank;



import android.app.TabActivity;

import android.content.Intent;

import android.os.Bundle;

import android.widget.TabHost;



 public class BetetAttekint extends TabActivity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);





TabHost tabhost=getTabHost();

TabHost.TabSpec spec;

Intent intent;



intent=new Intent().setClass(this, BetetAttekint.class);



spec=tabhost.newTabSpec("betet").setIndicator("Betétek Áttekintése").setContent(intent);

tabhost.addTab(spec);











}





}
