Why am I getting a “Permission Denied” error?

Question

I'm making an Android application that has to read some values from a JSON object. So to get the JSON object and read it, I have used the following method:

private void _init() {
    _rates = new HashMap<String, String>();

    URLConnection jsonURL = null;
    InputStream in = null;
    String jRatesStream = null;

    try {
        jsonURL = new URL(jRatesURL).openConnection();
        jsonURL.connect(); // ERROR OCCURING HERE
        in = jsonURL.getInputStream();
        jRatesStream = _convertStreamToString(in);

    } catch(Exception e) {
        Log.v("ERROR", "ERROR WHILE READING URL", e);

    } finally {
        try {
            in.close();
        } catch (Exception e) {
        }
    }

    try {
        JSONObject jObject = new JSONObject(jRatesStream);
        JSONObject jRates = jObject.getJSONObject("rates");

        Iterator<String> iterator = jRates.keys();
        while(iterator.hasNext()) {
            String key = iterator.next();
            _rates.put(key, String.valueOf(jRates.getDouble(key)));
        }

    } catch (Exception e) {
    }

}

And the jRatesURL String is this:

private static final String jRatesURL = "http://openexchangerates.org/latest.json";

But when executing this method, I get a "Permission Denied" error:

So what is the cause of this error? Am I doing something wrong when connecting to the JSON link?

Any help greatly appreciated. Thanks!

Answer 1

from here

String INTERNET Allows applications to open network sockets.

Use that permission in your manifest

 <uses-permission android:name="android.permission.INTERNET"></uses-permission>

Answer 2

Have you given the permission

<uses-permission android:name="android.permission.INTERNET" /> 

in the manifest?
