I have an application that communicates with a web server to retrieve some data, the application always working fine but now is showing this error :
javax.net.ssl.SSLException: Connection closed by peer
This only occur when i use a android < 4.4 if is 6.0 > it is working fine
public void volleyJsonObjectRequest(String url){
String REQUEST_TAG = "com.androidtutorialpoint.volleyJsonObjectRequest";
pDialog = new ProgressDialog(LoginActivity.this);
pDialog.setMessage("Efetuando login..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
json = new JSONObject(response);
userId = json.getString("userid");
userType = json.getString("usertype");
dbversion = json.getInt("dbversion");
success = json.getInt(TAG_SUCCESS);
message = json.getString(TAG_MESSAGE);
if (pDialog != null && pDialog.isShowing()) {
pDialog.dismiss();
}
enviadoComSucesso();
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
if (pDialog != null && pDialog.isShowing()) {
pDialog.dismiss();
}
userMsg("Não foi possível fazer conexão, por favor tenta novamente.");
}
}
) {
@Override
protected Map<String, String> getParams()
{
String usuario = LoginActivity.this.userTemp;
String password = LoginActivity.this.passTemp;
Map<String, String> param = new HashMap<>();
//ENVIO DOS DADOS DE AVALIAÇÕES
param.put("usuario", usuario);
param.put("password", password);
return param;
}
};
// Adding JsonObject request to request queue
AppSingleton.getInstance(getApplicationContext()).addToRequestQueue(postRequest,REQUEST_TAG);
postRequest.setRetryPolicy(new DefaultRetryPolicy(
2000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
}
Why is this error showing now? All my applications now have this error. When i see this error i search and found this solution by Sticky
The issue was due to TLSv1 being disabled on backend. Depending on the case there can be two approach to address this issue. 1. Enable TLSv1 on backend server. 2. As suggested, update the SSLEngine to support higher TLS versions on mobile app.
But i'm facing dificcult because is not VOLLEY APROACH, what i must do?
