    if (host != null && !host.equals("")) {
        boolean isWhite = false;
        for (String item : whitelist) {
            if (item.equals(host)) {
                isWhite = true;
                break;
            }
        }
        if (!isWhite) {
            // add to list
        }
    }
}

which package you've never seen? can you post more complete log and code which logged these lines? com.gau.go.launcherex is available HERE in Google Play, this is device launcher (what is launcher in HERE ). and simple android package may mean app is bring-back from background using some system option, eg recents button/menu

edit due code posted in question - some suggestions: instead of for loop just use whiteList.contains(host) , if you need to null /empty check host String then use TextUtils.isEmpty
