Hi,
This is no bug. The error messages reads : Your content must have a TabHost
whose id
attribute is 'android.R.id.tabhost'
Here's a sample :
<?xml version="1.0" encoding="utf-8"?>
<TabHost android:id="@android:id/tabhost" android:layout_width="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_height="fill_parent">
<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">
</FrameLayout>
</TabHost>
