Consuming a JSON from android What's wrong? [closed]

Navigation

I'm trying to get a Json from a web resource and convert it to string to show it on the screen. I am using android Studio for this and I can not consume that resource. Any idea that is wrong PS: In the manifests I have added the INTERNET and ACCESS_NETWORK_STATE permissions. 

public void getData(String URL) throws Exception {
    URL url = new URL(URL);
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

    InputStream in = new BufferedInputStream(urlConnection.getInputStream());
    JsonReader reader = new JsonReader(new InputStreamReader(in, "UTF-8"));

    reader.beginArray();
    while (reader.hasNext()){
        text.concat(reader.nextString());
    }
}

You can not make requests to the internet from the main thread, you can do it from an asyntask: The following link will be useful: link

PS: you usually put the error that shows you logcat.

The method should return the resource "String" or whatever you want and not be "void" if you want to use the result. 

    // read the JSON results into a string
    String jsonResult = in.readLine();
    return jsonResult;

It is also convenient that you do this activity in a secondary thread or thread.
