使用意图时如何将附件加载到 gmail？

Question

我有一个应用程序，我想发送一个带有多个 pdf 附件的 email。 一切似乎都正常工作，我没有遇到任何异常，但是当 Gmail 加载时，附件不包括在内。

我已经查看了有关 stackoverflow 和其他站点的许多问题，并遵循/测试了许多解决方案，但没有一个有效。 当然可以使用一些帮助。

以下是发送 email 的代码。

public void eMailDocument(ArrayList<Uri> files) {
          try {
              Log.i(TAG, "MainViewModel eMailDocument:  files = " + files);
              Intent intent = new Intent(ACTION_SEND_MULTIPLE);

              List<Intent> emailAppLauncherIntents = new ArrayList<>();
              PackageManager packageManager = context.getPackageManager();

              List<ResolveInfo> emailApps = packageManager.queryIntentActivities(intent, PackageManager.MATCH_ALL);

              for (ResolveInfo resolveInfo : emailApps) {
                  String packageName = resolveInfo.activityInfo.packageName;
                  Intent launchIntent = packageManager.getLaunchIntentForPackage(packageName);
                  emailAppLauncherIntents.add(launchIntent);
              }
              mSubjectLine = "CheckingIn app contact audit reports";
              Intent chooserIntent = Intent.createChooser(new Intent(ACTION_SEND_MULTIPLE), "Select email app:");
              chooserIntent.setAction(ACTION_SEND_MULTIPLE);
              chooserIntent.setType("application/pdf");
              //chooserIntent.setData(Uri.parse("mailto:"));
              chooserIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{mCurrentUserEmailAddress});
              chooserIntent.putExtra(Intent.EXTRA_SUBJECT, mSubjectLine);
              intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
              chooserIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
              chooserIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
              chooserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
              chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, emailAppLauncherIntents.toArray(new Parcelable[emailAppLauncherIntents.size()]));
              context.startActivity(chooserIntent);


            } catch(Exception e)  {
                System.out.println("is exception raises during sending mail"+e);
            }
        }

这是要添加的附件的“文件”元素中包含的数据

 files = [content://com.grgapps.checkingin.provider/external/Documents/allContactsAuditReport.pdf, content://com.grgapps.checkingin.provider/external/Documents/contactAppUsersAuditReport.pdf

我知道我迟到了，但这对我认为的人有用

Intent ei = new Intent(Intent.ACTION_SEND_MULTIPLE);
        ei.setType("plain/text");
        ei.putExtra(Intent.EXTRA_EMAIL, new String[] {"email id"});
        ei.putExtra(Intent.EXTRA_SUBJECT, "That one works");

        ArrayList<String> fileList = new ArrayList<String>();
        fileList.add(Environment.getExternalStorageDirectory()+"/foldername/certi/qualifications.jpg");
        fileList.add(Environment.getExternalStorageDirectory()+"/foldername/certi/certificate.jpg");
        fileList.add(Environment.getExternalStorageDirectory()+"/foldername/Aa.pdf");

        ArrayList<Uri> uris = new ArrayList<Uri>();
        //convert from paths to Android friendly Parcelable Uri's

        for (int i=0;i<fileList.size();i++)
        {
            File fileIn = new File(fileList.get(i));
            Uri u = Uri.fromFile(fileIn);
            uris.add(u);
        }

        ei.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
        startActivityForResult(Intent.createChooser(ei, "Sending multiple attachment"), 12345);
