DefaultHttpClientで文字化け

Question

以下の様なコードでandroidで東京メトロのAPIを使おうと思っているのですが、日本語が文字化けしてしまいます。
どうしたら良いですか？

class SimpleHttp extends AsyncTask<String, Void, String> {


    static final int GET = 0;
    static final int POST = 1;
    private int method;
    private String url;
    private ArrayList<NameValuePair> params = new ArrayList<NameValuePair>();

    public SimpleHttp(String url, int method, ArrayList<NameValuePair> params){
        this.url = url;
        this.method = method;
        this.params = params;
    }

    public SimpleHttp(String url, int method){
        this.url = url;
        this.method = method;
    }

    @Override
    protected String doInBackground(String... contents) {

        String response = null;
        int statusCode = 0;

        try {
            Log.d("url",url);

            if(method == GET) {
                HttpGet httpGet = new HttpGet(url);
                DefaultHttpClient client = new DefaultHttpClient();
                HttpResponse httpResponse = client.execute(httpGet);
                statusCode = httpResponse.getStatusLine().getStatusCode();
                HttpEntity entity = httpResponse.getEntity();
                response = EntityUtils.toString(entity);
                entity.consumeContent();
                client.getConnectionManager().shutdown();
            } else if(method == POST){
                HttpPost httpPost = new HttpPost(url);
                if(params != null){
                    httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
                } else {
                    throw new NullPointerException("パラメータが空だぜー");
                }
                DefaultHttpClient client = new DefaultHttpClient();
                HttpResponse httpResponse = client.execute(httpPost);
                statusCode = httpResponse.getStatusLine().getStatusCode();
                HttpEntity entity = httpResponse.getEntity();
                response = new String(EntityUtils.toString(entity).getBytes("UTF-8"), "UTF-8");
                entity.consumeContent();
                client.getConnectionManager().shutdown();
            }

            Log.d("status", Integer.toString(statusCode));
            Log.d("response", response);
            return response;

        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
    @Override
    protected void onPostExecute(String response) {
    }
}

EntityUtils.toStringの使い方が間違っているようです。

response = new String(EntityUtils.toString(entity).getBytes("ISO8859-1"), "UTF-8");

または

response = EntityUtils.toString(entity, "UTF-8");

としてみてください。

参考URL:
[EntityUtils#toString (Apache HttpCore 4.3.3 API)](https://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/util/EntityUtils.html#toString(org.apache.http.HttpEntity,%20java.lang.String%29)
