I've written codes that login and gets HTML of a specific web site.
String loginQuery = Sites.LOGIN_QUERY + "&member_no=" + id + "&password=" + pw;
HttpsURLConnection con;
con = (HttpsURLConnection) new URL(Sites.LOGIN_URL).openConnection();
con.setRequestMethod("POST");
con.setRequestProperty("Content-length", String.valueOf(loginQuery.length()));
con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
con.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0;Windows98;DigExt)");
con.setDoOutput(true);
con.setDoInput(true);
// Exception in this line...
DataOutputStream output = new DataOutputStream(con.getOutputStream());
output.writeBytes(loginQuery);
output.close();
The problem is that above code worked well however after updating to android 5.0, javax.net.ssl.SSLHandshakeException occurs. My device's previous OS version was 4.4.
I've changed nothing my code in the process of updating OS. How can I solve this ?
