visa direct on android

[smol987]

Hi There,

can you please assist? i am trying the helloworld example of visa direct using android platform. my keystore works on openssl but my app doesnot establish the connection (con.getResponseCode() = -1)  with the following code:

String auth = userId + ":" + password;
        byte[] encodedAuth = Base64.getEncoder().encode(auth.getBytes(StandardCharsets.UTF_8));
        String authHeaderValue = "Basic " + new String(encodedAuth);

        BufferedReader in;
        try{
            con.setRequestProperty("Authorization", authHeaderValue);
            int status = con.getResponseCode();
//        System.out.println("Http Status: " + status);

            if (status == 200) {
                in = new BufferedReader(new InputStreamReader(con.getInputStream()));
            } else {
                in = new BufferedReader(new InputStreamReader(con.getErrorStream()));
                System.out.println("Two-Way (Mutual) SSL test failed");
            }
            String response;
            StringBuffer content = new StringBuffer();
            while ((response = in.readLine()) != null) {
                content.append(response);
            }
            in.close();
            System.out.println(content.toString());

        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            con.disconnect();
        }

my error log:

Hi 

I managed to solve this issue by calling AsyncTask "android.os.NetworkOnMainThreadException occurs because you are making network call on your main UI Thread". so my code took this format:

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new Task().execute();

}

class MyDownloadTask extends AsyncTask<Void,Void,Void>
{
protected Long doInBackground(Void... params) {
URL url = new URL("https://sandbox.api.visa.com/vdp/helloworld");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
String responseMsg = con.getResponseMessage();
int response = con.getResponseCode();
return null;
}
}

thanks
