I am writing an app for android (2.1 > 3.1) and I would like to use the familiar practice of using the app Icon in Honeycomb apps to go up to the home activity, however, when I run the activity on earlier, non Honeycomb devices where the Activity.getActionBar(); method does not exist yet, the app force closes, how can I only run this specified code if the device is running honeycomb?

@Override
protected void onStart() {
    super.onStart();
    ActionBar actionBar = this.getActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);
}

Thanks for any help and have a great day.

    Android pre-Honeycomb doesn’t have an ActionBar, so any method concerning the actionBar will just fail. You should take a look at the code from the Google IO app, which uses an ActionBar both for Honeycomb and pre-Honeycomb.

    Put simply, it won’t work by itself, you’ll have to include your own ActionBar code.
