使用我的 Android 应用程序向我的朋友发送私人信息
原标题:Send private message to my friend(s) using my Android application

我正在开发一个应用程序, 用户可以与Facebook朋友分享讯息。 我使用Facebook API为Android服务。

我可以验证用户身份, 也可以拿到Facebook用户朋友名单, 也可以在墙上张贴信息, 但我正在寻找向朋友发送私人信息,

最佳回答

无法使用图Api代表用户发送私人信息。

不过,你应该可以使用“https:// developmenters.facebook.com/docs/reference/dialogs/send/”,尽管我还没有尝试过它,但应该像:

Bundle params = new Bundle();
params.putString("to", "USER_ID");
params.putString("name", "TITLE HERE");
params.putString("link", "A URL"); // this link param is required

facebook.dialog(context, "send", params, new DialogListener() {
    @Override
    public void onComplete(Bundle values) {
       ....
    }

    @Override
    public void onFacebookError(FacebookError error) {}

    @Override
    public void onError(DialogError e) {}

    @Override
    public void onCancel() {}
});

您也可以使用 < a href=" "https:// developmenters.facebook.com/docs/chat/" >Chat API 来代表用户发送信息,它需要 xmpp_login 许可,您也可以使用 xmppp 客户端。


Edit

由于尚未支持此对话框, 您有 3 个选项 :

  1. Wait for facebook to implement the dialog for android.
  2. Try to open the dialog in a browser (the url for that is in the docs) in the mobile device.
  3. Ask for the xmpp_login and add a xmpp client (i.e.: asmack) and with that you can implement your own "Send Message" dialog.

Latest Android SDK features now the (private) Message Dialog
https://developers.facebook.com/docs/android/message-dialog/

可以使用以下代码发送Facebook私人信息。

if (isPackageExisted("com.facebook.orca")) {
        Uri uri = Uri.parse("fb-messenger://user/");
        uri = ContentUris.withAppendedId(uri, Long.parseLong("Enter user id here"));
        Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(intent);
    } else {
        Toast.makeText(this, "Please install facebook messenger", Toast.LENGTH_LONG).show();
    }
}

检查 Facebook 信使是否安装是否安装

 public boolean isPackageExisted(String targetPackage) {
    PackageManager pm = getPackageManager();
    try {
        PackageInfo info = pm.getPackageInfo(targetPackage, PackageManager.GET_META_DATA);
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
    return true;
}
