意向+分享+ Action_Send_Multiple + Facebook的工作不 [英] Intent + Share + Action_Send_Multiple + Facebook not working

问题描述

我想使用意向sharing.It能够很好地处理单个图像，或当我使用Intent.ACTION_SEND。

I am trying to use Intent for sharing.It works well with single image or when I use Intent.ACTION_SEND.

但是当我使用Intent.ACTION_SEND_MULTIPLE这似乎并不为如我使用低于code在Facebook工作。

But when i use Intent.ACTION_SEND_MULTIPLE It does not seems to work on Facebook for e.g I am using below code.

    ArrayList<Uri> files = new ArrayList<Uri>();
    File a = new File(FileUtil.getDefaultMediaFolderPath(), "a.jpeg");
    File b = new File(FileUtil.getDefaultMediaFolderPath(), "b.jpeg");

    files.add(Uri.fromFile(a));
    files.add(Uri.fromFile(b));

    if (a.exists()) {
        if (b.exists()) {
            System.out.println("Both present.");
        }
    }

    Intent shareIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
    shareIntent.setType("*/*");
    shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
    startActivity(Intent.createChooser(shareIntent,"share via."));

以上code能够很好地处理Gmail和其附加的图片使用Gmail。但与Facebook似乎并不工作，图像不连接。

Above code works well with Gmail and it attaches the pics with Gmail. But with facebook it doesn't seems to work and images are not attached.

我曾尝试不同的组合，但似乎没有任何工作。虽然当我尝试从设备默认的库它运作良好，并重视所有的图像在Facebook的分享多张图片。

I have tried different combination but nothing seems to work. Although when I try to share multiple images from device default gallery it works well and attaches all the images in Facebook.

请帮助我！

推荐答案

在想很多事情最后，我来到了解决方案，在当前版本的Facebook打破了意向接受多张图片，而即将到来的意图。 ACTION_SEND_MULTIPLE。但我感到惊讶，当多个共享正在与默认的画廊在我的设备。 最后，我的朋友的帮助下（不是想邀功从他身上）。我才知道，默认画廊是在URI发送文件通过使用内容提供商这就是为什么他们是工作，所以我已经改变了我的URI列表为Facebook（我已创建自定义共享对话框，这样我就可以截获这些选项​​是从分享通过对话打开意图选择。）

After trying lots of things Finally I came to solution that In current version Facebook broke Intent for accepting Multiple Images while coming as Intent. ACTION_SEND_MULTIPLE. But I surprised when Multiple sharing is working with default Gallery in my device. Finally with the help of my friend (not wanted to take credit from him). I came to know that Default GAllery is sending files in URI by using Content Provider thats why they are working So I have changed my URI list for Facebook (I have created custom share dialog, So I can intercept which option is selected from Share Dialog opened via Intent.)

private void updateUrisForFacebook() {
    if (intent.getAction().equalsIgnoreCase(Intent.ACTION_SEND_MULTIPLE)) {
        ArrayList<Uri> uris = intent
                .getParcelableArrayListExtra(Intent.EXTRA_STREAM);
        for (int i = 0; i < uris.size(); i++) {
            Uri uri = uris.get(i);
            String path = uri.getPath();
            File imageFile = new File(path);
            uri = getImageContentUri(imageFile);
            uris.set(i, uri);
        }
        intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    }
}

private Uri getImageContentUri(File imageFile) {
    String filePath = imageFile.getAbsolutePath();
    Cursor cursor = context.getContentResolver().query(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            new String[] { MediaStore.Images.Media._ID },
            MediaStore.Images.Media.DATA + "=? ",
            new String[] { filePath }, null);
    if (cursor != null && cursor.moveToFirst()) {
        int id = cursor.getInt(cursor
                .getColumnIndex(MediaStore.MediaColumns._ID));
        Uri baseUri = Uri.parse("content://media/external/images/media");
        return Uri.withAppendedPath(baseUri, "" + id);
    } else {
        if (imageFile.exists()) {
            ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.DATA, filePath);
            return context.getContentResolver().insert(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        } else {
            return null;
        }
    }
}

最后，它的工作原理:)

Finally It works :)

所以，基本的想法是你的URI列表转换成内容提供商的URI列表，然后选中它会工作。的

So Basic Idea is to convert your URI list into Content provider URI list and then check it will work.
