How to programmatically determine if an Android Wear app supports?

Question

I am trying to determine if the app supports Android Wear or is a watchman.

PackageManager pm = getActivity().getPackageManager();

        List<PackageInfo> packs = pm.getInstalledPackages(0);
        for (int i = 0; i < packs.size(); i++)
        {}

Is im code used. Any feedback or suggestions would be terrible!

To check for Android Wear on your system:

public void foobar() {
    boolean doesExist = isPackageInstalled("com.google.android.wearable.app");
}

private boolean isPackageInstalled(String packagename) {
    PackageManager pm = getApplicationContext().getPackageManager();
    try {
        pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (NameNotFoundException e) {
        //swallow exception
        return false;
    }
}
