【中文标题】附件未以编程方式发送到邮件中

【英文标题】：Attachment is not coming in mail programmatically

【问题描述】：

我正在用代码将 TEXT 文件附加到电子邮件：

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",
                                    "[e-mail]", null));

    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Report");

    emailIntent.putExtra(Intent.EXTRA_TEXT, prepareBodyMail());
    File root = Environment.getExternalStorageDirectory();
    File file = new File(root, "/MyFolder/report.txt");

    Uri uri = Uri.fromFile(file);
    emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
    startActivity(Intent.createChooser(emailIntent, "Pick an Email provider"));

此代码与 Gmail、电子邮件 和其他应用程序完美配合

但这不是通过 Google 的INBOX 应用程序附加文件

只有身体和主体来了，没有任何依恋

我已通过Inbox Problem 向 Google 网上论坛报告此问题

任何人都可以帮助我在代码中缺少什么吗？

【问题讨论】：

嘿，您解决了问题还是仍在搜索。请尝试我提供的解决方案希望这对你有用

我仍在寻找解决方案。我也已向 Google 群组报告了该问题。希望能得到解决。

对我来说同样的问题，无法在任何地方找到解决方案。

遇到同样的问题 :(

@Kushal 你找到解决方案了吗？

【参考方案1】：

String fileLocation = Environment.getExternalStorageDirectory() + "/MyFolder/report.txt";    
String to[] = "[e-mail]";

Intent intentEmail = new Intent(Intent.ACTION_SEND);
intentEmail.setType("vnd.android.cursor.dir/email");
intentEmail.putExtra(Intent.EXTRA_EMAIL, to);
intentEmail.putExtra(Intent.EXTRA_STREAM, fileLocation);
intentEmail.putExtra(Intent.EXTRA_SUBJECT, "Subject");

startActivity(Intent.createChooser(intentEmail , "Pick an Email provider"));

【讨论】：

这也不适用于 Inbox 应用程序。我认为我们应该在意图中提供 Uri 类型参数 wirh Intent.EXTRA_STREAM kay 。这是您代码中的问题

【参考方案2】：

试试这个

     Uri myUri = Uri.parse("file://" + path);
     emailIntent.putExtra(Intent.EXTRA_STREAM, myUri);

【参考方案3】：

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] "[e-mail]");
intent.putExtra(Intent.EXTRA_SUBJECT, "subject here");
intent.putExtra(Intent.EXTRA_TEXT, "body text");
File root = Environment.getExternalStorageDirectory();
File file = new File(root, xmlFilename);
if (!file.exists() || !file.canRead()) 
    Toast.makeText(this, "Attachment Error", Toast.LENGTH_SHORT).show();
    finish();
    return;

Uri uri = Uri.fromFile("file://" + file);
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "Send email..."));

【讨论】：

这适用于 Gmail、电子邮件应用程序，但不适用于 Inbox 应用程序..

我已经提到我的代码适用于 Gmail 和电子邮件，但不适用于收件箱..

【参考方案4】：

  public void sendMailWithIntent(String emailTo,
                                   String subject, String emailText, List<String> filePaths) 
        try 
            //need to "send multiple" to get more than one attachment
            final Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
            emailIntent.setType("text/plain");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
                    Util.extractEmails(emailTo));
//            emailIntent.putExtra(android.content.Intent.EXTRA_CC,
//                    new String[]emailCC);
            emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
            emailIntent.putExtra(Intent.EXTRA_TEXT, emailText);
            ArrayList<Uri> uris = new ArrayList<Uri>();
            //has to be an ArrayList
            if (filePaths != null) 
                //convert from paths to Android friendly Parcelable Uri's
                for (String file : filePaths) 
                    File fileIn = new File(file);
                    Uri u = Uri.fromFile(fileIn);
                    uris.add(u);
                
            
            emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
            Intent chooser = Intent.createChooser(emailIntent, "Send mail...");
            activity.startActivityForResult(chooser, 1);
         catch (Exception e) 
            new ShowToast(context, e.getMessage());
        

    

调用方法

    List<String> list = new ArrayList<>();
    list.add(TO_ATTACH_ONE);
    list.add(TO_ATTACH_TWO);
    sendMailWithIntent(toAddresses, subject, body, list);

【参考方案5】：

ACTION_SENDTO 好像官方不支持附件。它仅适用于 Gmail 和默认电子邮件客户端，因为它们使用“未记录”功能。我发现发送带有附件的电子邮件的唯一方法是使用 ACTION_SEND。

我的解决方案：

public class EmailSender 

private static final String INTENT_DATA_SCHEME_EMAIL = "mailto:";
private static final String FILE_PROVIDER_AUTHORIZER = "com.smartinhalerlive.app.fileprovider";

private String subject;
private String body;
private File attachment;

public EmailSender(String subject, String body, File attachment) 
    this.subject = subject;
    this.body = body;
    this.attachment = attachment;


public void sendEmail(Context context, EmailSenderListener listener) 
    List<ResolveInfo> emailClients = getEmailClients(context);

    if (null != emailClients) 
        ResolveInfo defaultEmailClient = getDefaultEmailClient(emailClients);

        if (null != defaultEmailClient) 
            sendEmailUsingSelectedEmailClient(context, defaultEmailClient, listener);
         else 
            showSelectEmailClientsDialog(context, emailClients, listener);
        
    


private void showSelectEmailClientsDialog(Context context,
                                          List<ResolveInfo> emailClients,
                                          EmailSenderListener listener) 
    String[] emailClientNames = getEmailClientNames(context, emailClients);

    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    builder.setTitle(R.string.email_dialog_title);
    builder.setItems(emailClientNames, (dialog, which) -> 
                sendEmailUsingSelectedEmailClient(context, emailClients.get(which), listener);
