Gmail错误：添加图片附件时'cyk：无法创建本地附件'

Question

我的应用程序人们可以选择最多6个图像，在应用程序的最后我想将这些图像添加到电子邮件到相应的电子邮件地址。

系统工作，但当我添加：

i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);

gmail给出了这个错误：'cyk：无法创建本地附件'

经过一些测试我发现这是由于并非所有图像总是在那里，如果我添加所有图像它只发送最后一个。

这是代码：

 public void SendButtonDown(View v){
    Intent intent = getIntent();

    Uri MAIL_IMAGES_URI = Uri.parse("file://"+MAIL_IMAGES);
    Uri MAIL_IMAGES_URI2 = Uri.parse("file://"+MAIL_IMAGES2);
    Uri MAIL_IMAGES_URI3 = Uri.parse("file://"+MAIL_IMAGES3);
    Uri MAIL_IMAGES_URI4 = Uri.parse("file://"+MAIL_IMAGES4);
    Uri MAIL_IMAGES_URI5 = Uri.parse("file://"+MAIL_IMAGES5);
    Uri MAIL_IMAGES_URI6 = Uri.parse("file://"+MAIL_IMAGES6);

    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("message/rfc822");
    i.putExtra(Intent.EXTRA_EMAIL   , new String[]{"[email protected]"});
    i.putExtra(Intent.EXTRA_SUBJECT , "Subject");
    i.putExtra(Intent.EXTRA_TEXT    , textVar);
    i.setType("application/image");


    i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI2);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI3);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI4);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI5);
    i.putExtra(Intent.EXTRA_STREAM  , MAIL_IMAGES_URI6);


    try {
        startActivity(Intent.createChooser(i, "Send mail..."));
    } catch (android.content.ActivityNotFoundException ex){
        Toast.makeText(AanbiedenStap3.this, "no email installed", 
        Toast.LENGTH_SHORT).show();
    }
    finish();
}
}

这是完整的Logcat：

我修复了应用程序，如果你遇到这个问题，这里是修复：

public void SendButtonDown(View v){
    Intent intent = getIntent();

    List<String> filePaths = new ArrayList<>();
    if(MAIL_IMAGES != null) {
        filePaths.add(MAIL_IMAGES);
    }
    if(MAIL_IMAGES2 != null) {
        filePaths.add(MAIL_IMAGES2);
    }
    if(MAIL_IMAGES3 != null) {
        filePaths.add(MAIL_IMAGES3);
    }
    if(MAIL_IMAGES4 != null) {
        filePaths.add(MAIL_IMAGES4);
    }
    if(MAIL_IMAGES5 != null) {
        filePaths.add(MAIL_IMAGES5);
    }
    if(MAIL_IMAGES6 != null) {
        filePaths.add(MAIL_IMAGES6);
    }

    final Intent i = new Intent(Intent.ACTION_SEND_MULTIPLE);
    i.setType("text/plain");
    i.putExtra(Intent.EXTRA_EMAIL   , new String[]{"[email protected]"});
    i.putExtra(Intent.EXTRA_SUBJECT , "subject");
    i.putExtra(Intent.EXTRA_TEXT    , data);

    ArrayList<Uri> uris = new ArrayList<>();

    for (String file : filePaths){
        File fileIn = new File(file);
        Uri u = Uri.fromFile(fileIn);
        uris.add(u);
    }
    i.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    i.putExtra(Intent.EXTRA_STREAM, uris);
    startActivity(Intent.createChooser(i, "Send mail..."));

    finish();
}
}
