问题 发送网格 用于电子邮件

Question

我使用sendgrid进行电子邮件传递，但收到以下错误。我的代码低于错误。

Error:  Caused by: java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; or its superclasses (declaration of 'org.apache.http.conn.ssl.AllowAllHostnameVerifier' appears in /system/framework/framework.jar:classes3.dex)
at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144)
at  

电子邮件消息代码：

Email from = new Email("[e-mail]");
String subject = "Sending with SendGrid is Fun";
Email to = new Email("[e-mail]");
Content content = new Content("text/plain", "and easy to do anywhere, even with Java");
Mail mail = new Mail(from, subject, to, content);
//Toast.makeText(getApplicationContext(),System.getenv('"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"),Toast.LENGTH_LONG).show();
SendGrid sg = new SendGrid(System.getenv("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"));
Request request = new Request();
try {
request.setMethod(Method.POST);
request.setEndpoint("mail/send");
request.setBody(mail.build());
Response response = sg.api(request);
System.out.println(response.getStatusCode());
System.out.println(response.getBody());
System.out.println(response.getHeaders());
} catch (IOException ex) {

}

我已经尝试了堆栈溢出上所有可能的帖子。请帮助我做错了什么？

org.apache.http.conn.ssl.AllowAllHostnameVerifier

上述类已被删除 API 级别 22

您应该改用 HttpURLConnection 类。
