Android намерен использовать для facebook-share text AND link

Ответ 1

Я только что построил этот код, и он работает для меня:

private void shareAppLinkViaFacebook(String urlToShare) {
    try {
        Intent intent1 = new Intent();
        intent1.setClassName("com.facebook.katana", "com.facebook.katana.activity.composer.ImplicitShareIntentHandler");
        intent1.setAction("android.intent.action.SEND");
        intent1.setType("text/plain");
        intent1.putExtra("android.intent.extra.TEXT", urlToShare);
        startActivity(intent1);
    } catch (Exception e) {
        // If we failed (not native FB app installed), try share through SEND
        String sharerUrl = "https://www.facebook.com/sharer/sharer.php?u=" + urlToShare;
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(sharerUrl));
        startActivity(intent);
    }
}

Если вы собираетесь использовать обычные Android Sharing Intents, то, к сожалению, намерение обмена Facebook может принимать только один URL (убедитесь, что у него есть http://) и никакого дополнительного текстового сообщения. Это странное ограничение, которое на самом деле не имеет смысла.

Вы должны использовать фактический официальный отдельный Android Android SDK в своем проекте, чтобы получить полную функциональность обмена. Это дополнительная работа.

Я столкнулся с подобными проблемами. В конце концов, то, что я сделал, было направлением. Если они решили поделиться (в обычном намерении Android с помощью Facebook), создайте новое намерение с акциями, которое имеет только URL-адрес и нажимает его на facebook. Все другие параметры обмена (твиттер, сообщение, электронная почта) будут работать как обычно.

мой вопрос и решение находятся здесь:

Включение дополнительных возможностей Android Share Intent в зависимости от того, какой метод они предпочитают использовать

  String shareBody = "app string text " + act_txt + " more text! Get the app at http://www.appurl.com";

PackageManager pm = view.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(sharingIntent, 0);
for(final ResolveInfo app : activityList) {
     Log.i(TAG, "app.actinfo.name: " + app.activityInfo.name);
    //if((app.activityInfo.name).contains("facebook")) {
          if("com.facebook.katana.ShareLinkActivity".equals(app.activityInfo.name)) {


        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "http://www.appurl.com");
        startActivity(Intent.createChooser(sharingIntent, "Share idea"));
        break;
    } else {
        sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "app name");
        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
        startActivity(Intent.createChooser(sharingIntent, "Share"));
        break;
    }
}

В Lollipop (21) вы можете использовать Intent.EXTRA_REPLACEMENT_EXTRAS, чтобы переопределить намерение для определенных приложений.

https://developer.android.com/reference/android/content/Intent.html#EXTRA_REPLACEMENT_EXTRAS

private void doShareLink(String text, String link) {
  Intent shareIntent = new Intent(Intent.ACTION_SEND);
  shareIntent.setType("text/plain");
  Intent chooserIntent = Intent.createChooser(shareIntent, getString(R.string.share_via));

  // for 21+, we can use EXTRA_REPLACEMENT_EXTRAS to support the specific case of Facebook
  // (only supports a link)
  // >=21: facebook=link, other=text+link
  // <=20: all=link
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    shareIntent.putExtra(Intent.EXTRA_TEXT, text + " " + link);
    Bundle facebookBundle = new Bundle();
    facebookBundle.putString(Intent.EXTRA_TEXT, link);
    Bundle replacement = new Bundle();
    replacement.putBundle("com.facebook.katana", facebookBundle);
    chooserIntent.putExtra(Intent.EXTRA_REPLACEMENT_EXTRAS, replacement);
  } else {
    shareIntent.putExtra(Intent.EXTRA_TEXT, link);
  }

  chooserIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  startActivity(chooserIntent);
}

В моем приложении я включил Facebook SDK, чтобы пользователи могли делиться цитатой [предварительно заполненным текстом] на своей стене. Используя FB SDK, это можно сделать. Он работает в моем приложении, и у меня есть более 5 тысяч пользователей, которые используют то же самое.

По-видимому, это не противоречит политике FB, поскольку у меня не было никакого предупреждения или проблемы, когда это не сработало.

Здесь можно найти фрагменты кода,

У любого широко используемого приложения Android есть доступ к Facebook с предварительно заполненным текстовым полем?
