Android Json tag into String

Question

I use this code for reading a tag by a specific URL:

public static String ter(final String PRIVATE) {
    JsonParser parser = new JsonParser();
    try {
        Object obj = parser.parse(new FileReader("my url string"));
        JSONObject jsonObject = (JSONObject) obj;
        String event = (String) jsonObject.get("EVENT");
        return event;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return PRIVATE;
}

Then I set my subTitle with PRIVATE in this way:

getActionBar().setSubtitle("test"+ter(PRIVATE));

But when I run my app, in subTitle I read only text "test" with text "null" and it doesn't read the tag of JSON. Anyone has any idea? Is my code wrong?

Can you post your full JSON response? – Prokash Sarkar Aug 17 '15 at 07:12 — Prokash Sarkar, Aug 17 '15 at 07:12

Because you may have not initializes your variable therefore it is pointing towards null values....

When ever we create object,either by calling that method or by initializing variable at declaration, we can avoid null pointer exception...

If you performing this in your `Async Task` try to set your SubTitle in `onPostMethod` – Iamat8 Aug 18 '15 at 05:35

You are setting the subtitle to PRIVATE, but if your parsing succeeds, you're returningevent. You're also sending PRIVATE into this function, for some reason.
