Gson and Google
<p>I have the following code:</p>

<pre><code>public String test(){
        URL url = null;
        try {
            url = new URL("http://api.heroesofnewerth.com/player_statistics/ranked/nickname/Hieratic/?token=0CZGH8ZI7UR8J2GN");
        } catch (MalformedURLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        BufferedReader reader = null;
        String x = "";
        try {
            reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));
            for (String line; (line = reader.readLine()) != null;) {
                System.out.println(line);
                x = line;
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally{
            if (reader !=null) try{reader.close();} catch (IOException ignore) {
            }{}
        }
        JsonElement root = new JsonParser().parse(x);
        return x;
    }
}
</code></pre>

<p>now i want to insert the text into the following textView.</p>

<pre><code>protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_create_competetion);

    TextView tv = (TextView) findViewById(R.id.competetion_text);
    JsonCollector jc = new JsonCollector();

    tv.setText(jc.test());
</code></pre>

<p>However when i try to run it. i get the following error:</p>
