如何直接调用Facebook和VK的共享方法

Question

我试图从我想要的应用程序中调用共享方法，而不仅仅是调用允许共享的所有应用的列表。我正在使用此代码来调用Twitter共享：

String tweetUrl = 
            String.format("https://twitter.com/intent/tweet?text=%s&url=%s",
            "Tweet text", "https://www.google.fi/");
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(tweetUrl));
        // Narrow down to official Twitter app, if available:
        List<ResolveInfo> matches = getPackageManager().queryIntentActivities(intent, 0);
        for (ResolveInfo info : matches) {
            if (info.activityInfo.packageName.toLowerCase().startsWith("com.facebook")) {
                intent.setPackage(info.activityInfo.packageName);
            }
        }
        startActivity(intent);

这是为Facebook的：

String fullUrl = "https://m.facebook.com/sharer.php?u=..";
    try {
        Intent sharingIntent = new Intent(Intent.ACTION_SEND);
        sharingIntent.setClassName("com.facebook.katana",
                "com.facebook.katana.ShareLinkActivity");
        sharingIntent.putExtra(Intent.EXTRA_TEXT, "your title text");
        startActivity(sharingIntent);
    } catch (Exception e) {
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(fullUrl));
        startActivity(i);
    }

但它要求仅打开浏览器，而不是在电话上安装的Facebook应用程序

并且不知道该如何为VK

Answer 1

Facebook我只知道与此Facebook提要对话框共享

或

使用此浏览器的代码

Session.openActiveSession(this, true, new Session.StatusCallback()
    {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            if (session.isOpened()) {
                share(session);
            }
        }
    });
}
private void share(Session mySession) {
    String message = "bla";
Bundle bundle = new Bundle();
bundle.putString("caption", "caption");
bundle.putString("description", message);
bundle.putString("link", "link");
bundle.putString("name", "title");
bundle.putString("picture", "");
new WebDialog.FeedDialogBuilder(this, mySession, bundle).build().show();
}
