从应用程序发送邮件

我正在开发一个应用程序，我必须从应用程序发送邮件。邮件的正文和收件人不应该是可编辑的。所以我使用这个link一步一步地配置了gmail。从应用程序发送邮件

现在需要的应用是，FROM用户名和密码是由用户给出的。它可以是任何类型的：

[email protected], 
[email protected] 
[email protected]

该电子邮件应该发送，用户输入的用户名和密码由用户输入。我搜索了一下，并从yahoo id应用程序应该配置雅虎smtp服务器上发送邮件。

但是如果用户输入其他邮件编号。有没有一种应用程序可以发送邮件的常用方法？为此，我必须执行哪些步骤。

尝试这样，

 address = (EditText) findViewById(R.id.address); 
    subject = (EditText) findViewById(R.id.subject); 
    emailbody = (EditText) findViewById(R.id.body); 
    send = (Button) findViewById(R.id.send); 

    send.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      sendEmail(); 
     } 
    }); 
} 

public void sendEmail(){ 

    if(!address.getText().toString().trim().equalsIgnoreCase("")){ 
     final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
     emailIntent.setType("plain/text"); 
     emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ address.getText().toString()}); 
     emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject.getText()); 
     emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailbody.getText()); 
     sendMailDemo.this.startActivity(Intent.createChooser(emailIntent, "Send mail...")); 
    } 
    else{ 
     Toast.makeText(getApplicationContext(), "Please enter an email address..", Toast.LENGTH_LONG).show(); 
    }

我已经试过。但是通过这个代码，默认的作曲家是可以访问的。邮件正文和地址是可编辑的。我的应用程序需要的是，主体和地址不应该是可编辑的。 – 2013-03-11 12:38:55

如果您有Gmail，这是非常有用先下载从here 这3个库（邮件/活化/额外）它们添加到您的项目（将它们复制到项目/右击/添加到构建路径）

JSSEProvider类：

package com.emailsender; 

import java.security.AccessController; 

import java.security.Provider; 



public final class JSSEProvider extends Provider { 



public JSSEProvider() { 

super("HarmonyJSSE", 1.0, "Harmony JSSE Provider"); 

     AccessController 

       .doPrivileged(new java.security.PrivilegedAction<Void>() { 

        public Void run() { 

         put("SSLContext.TLS", 

           "org.apache.harmony.xnet.provider.jsse.SSLContextImpl"); 

         put("Alg.Alias.SSLContext.TLSv1", "TLS"); 

         put("KeyManagerFactory.X509", 

           "org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl"); 

         put("TrustManagerFactory.X509", 

           "org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl"); 

         return null; 

        } 

       }); 

    } 

}

     public OutputStream getOutputStream() throws IOException { 

      throw new IOException("Not Supported");

发送代码：

  new Thread(new Runnable() { 

       public void run() { 

        try { 

         GMailSender sender = new GMailSender(

           "[email protected]", 

           "yourpassword"); 



        sender.addAttachment(Environment.getExternalStorageDirectory().getPath()+"/image.jpg"); 

         sender.sendMail("your text", 

           "[email protected]", 

           "[email protected]"); 









        } catch (Exception e) { 

         Toast.makeText(getApplicationContext(),"Error",Toast.LENGTH_LONG).show(); 



        } 

       } 

      }).start();
