Gson – convert from Json to a typed ArrayList

Using the Gson library, how do I convert a JSON string to an ArrayList of a custom class JsonLog? Basically, JsonLog is an interface implemented by different kinds of logs made by my Android app–SMS logs, call logs, data logs–and this ArrayList is a collection of all of them. I keep getting an error in line 6.

public static void log(File destination, JsonLog log) {
    Collection<JsonLog> logs = null;
    if (destination.exists()) {
        Gson gson = new Gson();
        BufferedReader br = new BufferedReader(new FileReader(destination));
        logs = gson.fromJson(br, ArrayList<JsonLog>.class); // line 6
        // logs.add(log);
        // serialize "logs" again
    }
}

It seems the compiler doesn’t understand I’m referring to a typed ArrayList. What do I do?
