当我在我的应用程序上执行同步时,遇到此错误时出现问题.主要问题是相同的代码适用于
Android 6.0.1设备,但在4.4.2设备上,我收到此错误：

这里的关键是强制TLS 1.2协议,基于
this链接.
只需要在这里纠正的事情就是直接强制使用TLS 1.2协议,就像这样： private class NoSSLv3SSLSocket extends DelegateSSLSocket {
private NoSSLv3SSLSocket(SSLSocket delegate) {
super(delegate);
}
@Override
public void setEnabledProtocols(String[] protocols) {
super.setEnabledProtocols(new String[]{"TLSv1.2"}); // force to use only TLSv1.2 here
}
}
