Android HTTPS исключение Сброс соединения по пиру
Я работаю над приложением, которое загружает данные с веб-сервера. Вначале кажется, что данные загружаются без проблем, но несколько дней назад я начал получать исключения такого рода:javax.net.ssl.SSLException: Read error: ssl=0x7a6588: I/O error during system call, Connection reset by peer и я не уверен, что является причиной этой проблемы и как я могу это исправить. Вот и всяLogCat сообщение:

Это то, что я получил на своемUseHttpsConnection метод:
public void UseHttpsConnection(String url, String charset, String query) {
try {
final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
@Override
public void checkClientTrusted( final X509Certificate[] chain, final String authType ) {
}
@Override
public void checkServerTrusted( final X509Certificate[] chain, final String authType ) {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
} };
// Install the all-trusting trust manager
final SSLContext sslContext = SSLContext.getInstance( "TLS" );
sslContext.init( null, trustAllCerts, new java.security.SecureRandom() );
// Create an ssl socket factory with our all-trusting manager
final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
if (url.startsWith("https://")) {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){
public boolean verify(String hostname, SSLSession session) {
return true;
}});
}
System.setProperty("http.keepAlive", "false");
HttpsURLConnection connection = (HttpsURLConnection) new URL(url).openConnection();
connection.setSSLSocketFactory( sslSocketFactory );
connection.setDoOutput(true);
connection.setConnectTimeout(15000 /* milliseconds */ );
connection.setRequestMethod("POST");
connection.setRequestProperty("Charset", charset);
connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded;charset=" + charset);
OutputStream output = null;
try {
output = connection.getOutputStream();
output.write(query.getBytes(charset));
} catch (IOException e) {
e.printStackTrace();
showError2("Check your network settings!");
} finally {
if (output != null)
try {
output.close();
} catch (IOException logOrIgnore) {
logOrIgnore.printStackTrace();
}
}
int status = ((HttpsURLConnection) connection).getResponseCode();
Log.d("", "Status : " + status);
for (Entry<String, List<String>> header : connection
.getHeaderFields().entrySet()) {
Log.d("Headers","Headers : " + header.getKey() + "="+ header.getValue());
}
InputStream response = new BufferedInputStream(connection.getInputStream());
int bytesRead = -1;
byte[] buffer = new byte[30 * 1024];
while ((bytesRead = response.read(buffer)) > 0) {
byte[] buffer2 = new byte[bytesRead];
System.arraycopy(buffer, 0, buffer2, 0, bytesRead);
handleDataFromSync(buffer2);
}
connection.disconnect();
} catch (IOException e) {
e.printStackTrace();
showError2("Synchronization failed!Please try again.");
} catch (KeyManagementException e) {
e.printStackTrace();
showError2("Error occured.Please try again.");
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
showError2("Error occured.Please try again.");
}
}
А вот мой AsyncTask, который я использую для подключения и загрузки данных:
public class DeactivateCollection extends AsyncTask <Context, Integer, Void> {
@Override
protected Void doInBackground(Context... arrContext) {
try {
String charset = "UTF-8";
hash = getAuthHash();
SharedPreferences lastUser = PreferenceManager
.getDefaultSharedPreferences(Synchronization.this);
int userId = lastUser.getInt("lastUser", 1);
systemDbHelper = new SystemDatabaseHelper(Synchronization.this, null, 1);
systemDbHelper.initialize(Synchronization.this);
String sql = "SELECT dbTimestamp FROM users WHERE objectId=" + userId;
Cursor cursor = systemDbHelper.executeSQLQuery(sql);
if (cursor.getCount() < 0) {
cursor.close();
} else if (cursor.getCount() > 0) {
cursor.moveToFirst();
timeStamp = cursor.getString(cursor.getColumnIndex("dbTimestamp"));
Log.d("", "timeStamp : " + timeStamp);
}
String query = String.format("debug_data=%s&"
+ "client_auth_hash=%s&" + "timestamp=%s&"
+ "deactivate_collections=%s&" + "client_api_ver=%s&"
+ "set_locale=%s&" + "device_os_type=%s&"
+ "device_sync_type=%s&"
+ "device_identification_string=%s&"
+ "device_identificator=%s&" + "device_resolution=%s",
URLEncoder.encode("1", charset),
URLEncoder.encode(hash, charset),
URLEncoder.encode(timeStamp, charset),
URLEncoder.encode(Integer.toString(deac), charset),
URLEncoder.encode(clientApiVersion, charset),
URLEncoder.encode(locale, charset),
URLEncoder.encode(version, charset),
URLEncoder.encode("14", charset),
URLEncoder.encode(version, charset),
URLEncoder.encode(deviceId, charset),
URLEncoder.encode(resolution, charset));
Log.e("","hash : "+hash);
Log.e("","deactivate : "+Integer.toString(deac));
SharedPreferences useSSLConnection = PreferenceManager.getDefaultSharedPreferences(Synchronization.this);
boolean useSSl = useSSLConnection.getBoolean("UseSSl", true);
if (useSSl) {
UseHttpsConnection(url, charset, query);
} else {
UseHttpConnection(url, charset, query);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onProgressUpdate(Integer... progress) {
Log.d("","ON PROGRESS UPDATE");
}
@Override
protected void onCancelled() {
Log.d("","ON CANCELLED");
}
@Override
protected void onPreExecute()
{
Log.d("","ON PRE EXECUTE");
}
@Override
protected void onPostExecute(Void v) {
Log.d("","ON POST EXECUTE");
}
}
Так что у каждого есть идея, как обработать это исключение, чтобы я мог загрузить все данные без каких-либо исключений. Или как я могу это исправить, если это невозможно.
Заранее спасибо!
