Answer：
If you have to use that menu use the following lines in your Manifest file:
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="9" >
</uses-sdk>
Answer：
But sometimes you want a fullscreen app…for example in the Manifest is setted the activity with:
android:theme="@android:style/Theme.NoTitleBar"
The only and ugly fix is to set under the target sdk version:
