我使用Android系統的查詢，使HTTP調用，我不斷收到隨機SSLExceptions，像這樣的：Android的查詢 - 隨機SSLExceptions

似乎沒有無緣無故爲他們的出現。當我撥打任何電話時，它們可能只有1/6發生。
這裏是我如何使用Android系統的查詢（$）：
//創建應用程序：
public void onCreate()
{
AQUtility.setExceptionHandler(new UncaughtExceptionHandler() {
public void uncaughtException(Thread thread, Throwable ex)
{
ex.printStackTrace();
}
});
AQUtility.setDebug(true);
AjaxCallback.setTransformer(new JsonTransformer());
//set the max number of concurrent network connections, default is 4
AjaxCallback.setNetworkLimit(8);
//set the max number of icons (image width <= 50) to be cached in memory, default is 20
BitmapAjaxCallback.setIconCacheLimit(20);
//set the max number of images (image width > 50) to be cached in memory, default is 20
BitmapAjaxCallback.setCacheLimit(40);
//set the max size of an image to be cached in memory, default is 1600 pixels (ie. 400x400)
BitmapAjaxCallback.setPixelLimit(480 * 480);
//set the max size of the memory cache, default is 1M pixels (4MB) (2---)
BitmapAjaxCallback.setMaxPixelLimit(4000000);
super.onCreate();
}
//用法 //注意：URI = // 07-13 17：26：08.040：W/AQuery（7746）：得到：https://site.com/me/ticker/
$.auth(Security.getAuth(this)).ajax(uri, BaseModelListRequest.class, this, "loadAdapterObjectsCallback");
public void loadAdapterObjectsCallback(String uri, BaseModelListRequest requestData, AjaxStatus status)
{
setProgressBarIndeterminateVisibility(false);
setSupportProgressBarIndeterminateVisibility(false);
if(requestData != null && status.getCode() == 200)
{
// stuff
}
}
//這裏是GETAUTH：
public static synchronized BasicHandle getAuth(Context context)
{
return new BasicHandle("user", "pass");
}
//及JSONTRANSFORMER（使用jaxson馬歇爾JSON）：
public class JsonTransformer implements Transformer
{
public <T> T transform(String url, Class<T> type, String encoding, byte[] data, AjaxStatus status)
{
ObjectMapper mapper = new ObjectMapper();
try
{
return mapper.readValue(new String(data), type);
}
catch(Exception e)
{
return null;
}
}
}
編輯：這發生在2.x和3.x，使用SSL。禁用SSL（https - > http）可以使其工作。
這裏是另一個例外，SSL：

編輯2：
進一步檢查產率在Android 2.3.x版本設備發生錯誤。刪除協議中的「s」（即SSL）使一切正常工作。
我以前曾就此問題與RestTemplate（Spring的Android設備），並按照這篇文章的建議修復它：Self-signed SSL acceptance on Android
但是，我修改了源Android的查詢以同樣的方式，纔沒有解決問題。
