在本文中，我們將發(fā)送一封電子郵件，其中包含精心設(shè)計(jì)的表單以顯示與郵件一起發(fā)送的數(shù)據(jù)。
眾所周知，對(duì)我們所有人來(lái)說(shuō)，使用電子郵件已經(jīng)變得十分必要和重要。有各種電子郵件服務(wù)提供商，例如Yahoo，Outlook，iCloud和Gmail等。這些技術(shù)巨頭為每個(gè)用戶提供免費(fèi)的電子郵件服務(wù)。如果您使用互聯(lián)網(wǎng)，則無(wú)法忽略它，因?yàn)槊慨?dāng)您訪問(wèn)任何網(wǎng)站/應(yīng)用程序以在線購(gòu)買/銷售產(chǎn)品時(shí)，都可以。首先，您必須在這些網(wǎng)站/應(yīng)用程序上注冊(cè)才能證明您在現(xiàn)實(shí)世界中的身份。
在本文中，我們將學(xué)習(xí)如何使用JavaMail API將Gmail收件箱中的電子郵件發(fā)送到指定的電子郵件地址。我們將發(fā)送常見(jiàn)的用戶數(shù)據(jù)，例如用戶名，電子郵件地址，手機(jī)號(hào)碼。等等
因此，讓我們開(kāi)始吧。
步驟1
- 首先，創(chuàng)建空的android項(xiàng)目，并在根目錄中創(chuàng)建名稱為MailSender.java和JSSEProvider.java的Java類。
- 現(xiàn)在，我們需要將Java Mail API jar文件導(dǎo)入到我們的項(xiàng)目中。從此處下載jar文件，解壓縮并將其粘貼到libs文件夾中。
- 如果您的項(xiàng)目無(wú)法識(shí)別您的庫(kù)，請(qǐng)重新啟動(dòng)Android Studio。
- 右鍵單擊app-> New-> Folder-> Assets Folder，創(chuàng)建資產(chǎn)文件夾。我們將HTML文件放在此處，以在Gmail上顯示數(shù)據(jù)。
- 要發(fā)送電子郵件，您的應(yīng)用將需要互聯(lián)網(wǎng)連接，因此請(qǐng)?jiān)?em>AndroidManifest.xml文件中聲明此權(quán)限。
<uses-permission android:name="android.permission.INTERNET"/>
第2步
- 在MailSender.java類中創(chuàng)建一些實(shí)例變量
// change this host name accordingly
private String mailhost = "webmail.xyz.in";
private String user;
private String password;
private Session session;
Context context;
private Multipart _multipart = new MimeMultipart();
- 現(xiàn)在，在MailSender.java文件中創(chuàng)建靜態(tài)塊以調(diào)用JSSEProvider.java類。JSSEProvider用于鏈接SSLContext，X509的KeyManagerFactory，X509的TrustManagerFactory和AndroidCAstore的修改版本。
static {
Security.addProvider(new JSSEProvider());
}
- 創(chuàng)建參數(shù)化的構(gòu)造函數(shù)（傳遞上下文，“發(fā)件人電子郵件ID”和“密碼”等）以初始化實(shí)例變量，并創(chuàng)建Properties類的對(duì)象以在構(gòu)造函數(shù)內(nèi)設(shè)置屬性。在其中傳遞上下文，用戶電子郵件ID和密碼?？匆幌聵?gòu)造函數(shù)代碼。
public MailSender(Context context,String user, String password) {
this.user = user;
this.password = password;
this.context = context;
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", mailhost);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.quitwait", "false");
session = Session.getDefaultInstance(props, this);
}
- 創(chuàng)建密碼驗(yàn)證器方法以驗(yàn)證您的帳戶。
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
- 最后，創(chuàng)建用戶定義的方法sendUserDetailWithImage（）以將數(shù)據(jù)發(fā)送到郵件。下面的代碼從assets文件夾中提取user_profile.html，將其轉(zhuǎn)換為緩沖區(qū)，然后從緩沖區(qū)中讀取它，最后將其轉(zhuǎn)換為字符串對(duì)象，用實(shí)際的用戶名替換關(guān)鍵字“
”等等。請(qǐng)參閱完整的sendUserDetailWithImage（）代碼。
public synchronized void sendUserDetailWithImage(String subject, String body,
String sender, String recipients,String username,String email,String mobile,String dob,String age,String address,String profilePic ) throws Exception {
MimeMessage message = new MimeMessage(session);
DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));
message.setFrom(new InternetAddress("no-reply@astromyntra.in"));
message.setSender(new InternetAddress(sender));
message.setSubject(subject);
message.setDataHandler(handler);
BodyPart messageBodyPart = new MimeBodyPart();
InputStream is = context.getAssets().open("user_profile.html");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String str = new String(buffer);
str =str.replace("$$headermessage$$","You have got a new user.");
str=str.replace("$$username$$", username);
str=str.replace("$$email$$", email);
str=str.replace("$$mobile$$", mobile);
str=str.replace("$$dob$$",dob);
str=str.replace("$$age$$",age);
str=str.replace("$$address$$", address);
messageBodyPart.setContent(str,"text/html; charset=utf-8");
_multipart.addBodyPart(messageBodyPart);
// Put parts in message
message.setContent(_multipart);
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));
Transport.send(message);
}

HTML代碼的輸出看起來(lái)像這樣
第四步
最后，將以下代碼粘貼到您的MainActivity中。
package com.emailsender;
import androidx.appcompat.app.AppCompatActivity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void sendMail(View view)
{
new MailCreator().execute("");
}
public class MailCreator extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... strings) {
try {
MailSender sender = new MailSender(getBaseContext(), AppsConstants.SENDER_EMAIL,AppsConstants.SENDER_PASSWORD);
sender.sendUserDetailWithImage("New User Added", "Hi", "Himanshu",
AppsConstants.RECIPEINT_MAIL, "Himanshu Verma", "xyz@gmail.com", "+91 6075959010", "02/02/1994", "25","New Delhi, India","");
} catch (Exception e) {
Log.e("SendMail", e.getMessage(), e);
}
return null;
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
// Toast.makeText(getActivity(),"Mail Sent",Toast.LENGTH_LONG).show();
}
}
}
