Javamail api沒有發送任何郵件

我使用the link從我的android應用程序發送html郵件。但它不發送任何郵件。這裏我有一個保存在SD卡中的HTML頁面，它被用作HTML的主體內容。問題是什麼？我該如何解決這個問題？Javamail api沒有發送任何郵件

[Rü得到任何錯誤？ – Randroid

No.i沒有得到任何迴應。 –

那麼你的logcat說什麼？你有沒有檢查過？你有沒有添加這些1）activation.jar 2）additionnal.jar 3）mail.jar在你的清單中的項目構建路徑和互聯網許可？（在所提到的鏈接，我看到這些） – Randroid

public void sendMail(){ 
       String tempAddress = emailTo.getText().toString(); 
       String[] toArr = tempAddress.split(","); 
       String FROM = emailFrom.getText().toString(); 
       String SUBJECT = emailSubject.getText().toString(); 

       boolean valid = false; 
       for (int counter = 0; counter < toArr.length; counter++) { 

        if (isValidEmail(toArr[counter])) { 
         valid = true; 
        } else { 
         valid = false; 
        } 
       } 
       if (valid && isValidEmail(FROM)) { 
        Mail m = new Mail("username", 
          "password"); 
        m.setTo(toArr); 
        m.setFrom(FROM); 
        m.setSubject(SUBJECT); 
        m.setBody("<html><body bgcolor='#FFFFFF'>your html content</body></html>"); 
        try { 
         if (m.send()) { 
          Toast.makeText(context, 
            "A test Email was sent successfully.", 
            Toast.LENGTH_LONG).show(); 
         } else { 
          Toast.makeText(context, "Email was not sent.", 
            Toast.LENGTH_LONG).show(); 
         } 
        } catch (Exception e) { 
         Toast.makeText(context, 
           "There was a problem sending the email.", 
           Toast.LENGTH_LONG).show(); 
        } 
        finish(); 

       } else { 
        Toast.makeText(context, "Please enter a valid e-mails.", 
          Toast.LENGTH_LONG).show(); 
       } 
      }

使用上面的代碼來發送郵件，並創建一個類郵件在烏爾包象下面這樣： -

見我的答案在下面的線程

Fail to send mail using JavaMail API

在那裏我舉了一個實例來發送郵件使用JavaMail

另請參閱我的回答了這一主題：Connecting directly to GMAIL with android
