How I hide the menu button for one activity

Question

There is an activity which has no menu item. So I want to hide the menu button. Is there any way to achieve that? Thanks

I figured out how this can be done. In your AndroidManifest.xml, you need to specify something like the following:

<uses-sdk android:minSdkVersion="8"
          android:targetSdkVersion="14" />

Basically, minSdkVersion is the minimum Android SDK version that you application supports (in my case, 2.2) and targetSdkVersion is the version you're "targetting" (i.e. your "preferred" version - in my case, that's 4.0)

By default, targetSdkVersion is the same as minSdkVersion, and if you leave that pre-Honeycomb, you're basically telling Android that your app is "legacy" and it'll always show the menu button.

If you make targetSdkVersion post-Honeycomb, then the menu button will only be shown if you actually have menu items defined.
