在我的应用程序中，当用户手动清除应用程序缓存时，他们将开始收到错误＆＃34;未找到证书路径的信任锚＆＃34;。
我的设置如下：应用程序具有中央服务器的硬编码URL。此中央服务器将告知应用程序可以登录的API的URL。连接到中央服务器时，该应用会创建一个同步帐户，并将此网址存储为同步帐户中的UserData。
当用户清除缓存后，登录后，他们将开始获取此异常，即使重启设备，该异常也会持续存在。
但是，当他们删除同步帐户并再次通过中央服务器登录时，问题就会消失。这是URLConnectionHelper中触发问题和堆栈跟踪的代码。 （我的代码是com.my.package）
public static InputStream getInputStream(AppUser appUser, String fullpath, Map<String, ?> params, Method method) throws IOException
{
URL url = new URL(fullpath + getQuery(params));
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
if (appUser != null)
conn.setRequestProperty("X-AuthToken", appUser.getToken());
if (method == Method.POST || method == Method.PUT)
conn.setDoOutput(true);
conn.setRequestMethod(method.toString());
conn.connect(); // <-- line 69
return new BufferedInputStream(conn.getInputStream(), 8192);
}
