我正在创建一个Android相机应用程序,我想将它连接到Facebook。 我为我的应用创建了一个页面并创建了一个Open Graph故事" x使用MyApp"拍摄了一张照片。 我使用的是OpenGraphActionDialogBu​​ilder,但出于某种原因,我已经能够在创建的OpenGraphActionDialog中看到附加图像的预览。

这是我的代码:

    public void shareWithFacebook(File imageFile) {

    // get session
    Session session = Session.getActiveSession();

    // make sure we have publish permissions
    boolean hasPublishPermissions = hasPublishPermission();
    if (!hasPublishPermissions) {
        if (!session.isOpened()) {
            Session.OpenRequest openRequest = new Session.OpenRequest(this);
            openRequest.setPermissions("user_friends");
            session.openForRead(openRequest);
        }
        requestPublishPermissions(session);
    }

    ArrayList<File> files = new ArrayList<File>();
    files.add(imageFile);

    OpenGraphAction action = OpenGraphAction.Factory.createForPost("mycameraapp:took");
    OpenGraphObject picture = OpenGraphObject.Factory.createForPost("mycameraapp:picture");
    picture.setProperty("title", "");

    action.setProperty("picture", picture);

    FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(this, action, "picture" )
            .setImageAttachmentFilesForObject("picture", files, true)
            .build();
    if (FacebookDialog.canPresentOpenGraphActionDialog(this))
        shareDialog.present();
}

您需要添加:

 action.setProperty("previewPropertyName", picture);
