Webサーバーからデータをダウンロードしているアプリケーションで作業しています。最初は問題なくデータをダウンロードしているようですが、数日前にこの種の例外が発生します：javax.net.ssl.SSLException: Read error: ssl=0x7a6588: I/O error during system call, Connection reset by peerと私はその問題の原因とどのように私はそれを修正することができますか分からない。ここでは、全体LogCatメッセージです：Android HTTPS例外ピアによって接続がリセットされました

これは私が私のUseHttpsConnection方法で得たものである：
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.");
}
}
そして、ここでは、私は、データを接続し、ダウンロードして使用しています私のAsyncTaskです：
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");
}
}
誰もがその例外を処理する方法を知っているので、例外なくすべてのデータをダウンロードできます。それが不可能な場合、どうすれば解決できますか？
ありがとうございます！
