多张照片未使用Intent发送到gmail

Question

我是android的新手，正在尝试使用Intent将多个文件发送到gmail。但它并没有发送附件。请帮我一下。

下面是我的代码：

Intent targetedShare = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
        targetedShare.setType("image/*"); // put here your mime type
        targetedShare.putExtra(Intent.EXTRA_SUBJECT, "Amplimesh Photo");
        targetedShare.putExtra(Intent.EXTRA_TEXT,"Attached the Quote");
        ArrayList<Uri> uris = new ArrayList<Uri>();
        //Fetching the Installed App and open the Gmail App.
        for(int index = 0; index < productList.size(); index++) {
            ByteArrayInputStream byteInputStream = new ByteArrayInputStream(productList.get(index).getOverlayBitmap());
            Bitmap overLayBitmap = BitmapFactory.decodeStream(byteInputStream);
            String fileName = SystemClock.currentThreadTimeMillis() + ".png";
            //Save the bitmap to cache.
            boolean isSaved = Helper.saveImageToExternalStorage(overLayBitmap, getApplicationContext(), fileName);
            if(isSaved)
                uris.add(Uri.fromFile(new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/amplimesh", fileName)));
        }
        targetedShare.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
        startActivityForResult(Intent.createChooser(targetedShare, "Sending multiple attachment"), 12345);

更新

尝试像这样的全路径

uris.add(Uri.fromFile(new File(Environment.getExternalStorageDirectory()+"/foldername/certi/qualifications.jpg")));

使用这个

Intent share = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE); 

而不是

Intent share = new Intent(android.content.Intent.ACTION_SEND);

试试这个

 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);

以下是我们prj 中的示例工作代码

ArrayList<Uri> imageUris = new ArrayList<Uri>();
imageUris.add(Uri.fromFile(new File("/mnt/sdcard/Medplann/IMG.jpg"))); // Add your image URIs here
imageUris.add(Uri.fromFile(new File("/mnt/sdcard/Medplann/Report.pdf")));
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "Share images to.."));

请尝试以下代码，这些代码是我在一个项目中用于多个附件的。

public static void sendEmailWithMultipleAttachment(Context context,
        String caption, ArrayList<String> fileList) {
    Intent emailIntent = new Intent(
            android.content.Intent.ACTION_SEND_MULTIPLE);
    emailIntent.setType("application/octet-stream");
    emailIntent.setType("message/rfc822"); // use from live device
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, caption);
    ArrayList<Uri> uris = new ArrayList<Uri>();
    for (String file : fileList) {
        File fileIn = new File(file);
        Uri u = Uri.fromFile(fileIn);
        uris.add(u);
    }
    emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    context.startActivity(Intent.createChooser(emailIntent,
            "Select email application."));
}

这里，ArrayList<String> fileList将是图像或任何文件的路径数组。
