android-Your content must have a TabHost whose id attribute is 'android.R.id.tabhost'

问题

Hi i created one customised tab bar with three tabs. I loaded one tab with google link, another with the small hello world app and another with the layout which has design for different screen resolutions. When i tap on the third tab it is showing an error "Your content must have a TabHost whose id attribute is 'android.R.id.tabhost'". But it is not showing that error when i load the third tab with small app. Why is it happening like that? Can any one help me?

Error:

If you are going to use TabActivity, you need to use @android:id/tabhost as the android:id value of your TabHost in your xml layout file
