    </application>
    <uses-sdk android:minSdkVersion="4" />
</manifest> 

By default Android will manage your layout automatically when you switch between landscape and portrait. If this causes problems for you or doesn't look right then you can always specify separate layouts:

res/layout/somePage.xml
res/layout-land/somePage.xml

Are your XML files named the same in both folders? What is happening exactly, is it crashing? is it not rotating? Do both files contain the same Views with the same IDs so your code can access them no matter which one is loaded?

I think the following code will be helpful for you. in this code u can give your manifest file which activity orientation you need.

android:configChanges="keyboardHidden|orientation"
