無法在pdf中附加pdf到郵件中

我正在嘗試創建pdf並通過電子郵件發送。現在我已經成功完成了pdf一代。當我嘗試將PDF附加到郵件併發送時，我收到錯誤。無法在pdf中附加pdf到郵件中

我想是這樣的：

private void sendMail(Uri URI) { 
     try { 
      // Uri URI = null; 

      String email = emailFromDB; 

      String subject = "Report For the day " + getDateTime(); 

      String message = "Report For the day " + getDateTime(); 

      final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
      emailIntent.setType("application/pdf"); 
      emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] { email }); 
      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,subject); 

      if (URI != null) { 
       emailIntent.putExtra(Intent.EXTRA_STREAM, URI); 
      } 

      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message); 
      emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      this.startActivity(Intent.createChooser(emailIntent,"Sending email...")); 

     } catch (Throwable t) { 

      Toast.makeText(this, 

      "Request failed try again: " + t.toString(), 

      Toast.LENGTH_LONG).show(); 

     } 

    }

，當我嘗試發送我得到這個erroe。

這裏我得到了FileNotFoundException erroe。但我在這個位置有pdf。（/mnt/sdcard/MyMenu/2015-05-07 22-50-39-Report.pdf）

請讓我知道我犯的錯誤。

「URI」似乎格式不正確。我不知道你從哪裏得到它。它沒有一個計劃。如果你從'File'創建它，使用'Uri.fromFile（）'創建'Uri'值。另外請注意，您不能同時使用'EXTRA_TEXT'和'EXTRA_STREAM'以及'ACTION_SEND'。選擇一個並使用它，根據您的選擇在「Intent」上設置MIME類型。 – CommonsWare

嗨@CommonsWare ..嗨@CommonsWare ..謝謝你的提示..我會檢查，並讓你現在知道.. –

超.. :-)現在我可以發送郵件附件..謝謝@CommonsWare ..請張貼您的答案..！！ –

所以芬利我得到的溶液（@CommonsWare給出提示）..

sendMail(Uri.fromFile(emailFilePath));

發送電子郵件方法： -

private void sendMail(Uri URI) { 
     try { 

      String email = emailFromDB; 

      String subject = "Report For the day " + getDateTime(); 

      String message = "Report For the day " + getDateTime(); 

      final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
      emailIntent.setType("application/pdf"); 
      emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] { email }); 
      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,subject); 

      if (URI != null) { 
       emailIntent.putExtra(Intent.EXTRA_STREAM, URI); 
      } 

      emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
      this.startActivity(Intent.createChooser(emailIntent,"Sending email...")); 

     } catch (Throwable t) { 

      Toast.makeText(this, 

      "Request failed try again: " + t.toString(), 

      Toast.LENGTH_LONG).show(); 

     } 

    }

在這裏，我已刪除emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);並獲得URI像Uri.fromFile(emailFilePath)。這解決了我的問題。感謝@CommonnsWare .. !!!
