Android Facebookの共有意図-テキストの共有とリンク
私はAndroid共有意図をFacebookに何かを投稿するために使用しようとしています。これは次のようになります。
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.setType("text/plain");
shareIntent.putExtra(Android.content.Intent.EXTRA_TEXT, "Free education for all! http://linkd.in/xU8mCc");
startActivity(shareIntent);
だから私の投稿には両方があります-いくつかのテキストとリンク。しかし、メッセージがFacebookに投稿されると、リンクのみが表示され、メッセージは表示されません。さまざまな追加機能を試しましたが、何も機能しません。
誰もがこの問題に直面して解決しましたか？ Facebookアプリバージョン1.8.1があります
編集：リンクを削除しようとしましたが、Facebookアプリは私のメッセージを受け取りません（投稿する空白のメッセージを表示します）が、その逆はしません。アプリはプレーンテキストメッセージを完全に無視しているようです。怖い！これは、テキストメッセージを（共有の意図を持って）まったく投稿できないというfbアプリの大きなバグですか？
私はこのコードを作成したばかりで、私のために働いています：
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);
}
}
通常のAndroid共有インテント）を使用する場合、残念ながらFacebook共有インテントは単一のURL（http：//があることを確認してください）のみを受け取り、追加のテキストメッセージはありません。本当に意味をなさない奇妙な制限です。
完全な共有機能を利用するには、プロジェクトで実際の公式の別のFacebook Android SDKを使用する必要があります。これは追加の作業です。
私は同様の問題に出くわしました。結局、私がしたことは意図を分岐させることでした。 Facebook経由で共有することを選択した場合（通常のAndroid共有インテント）、URLのみを持つ新しい共有インテントを作成し、それをFacebookにプッシュします。他のすべての共有オプション（Twitter、メッセージ、電子メール）は通常のように機能します。
私の質問と解決策はここにあります：
Android共有するために選択した方法に応じて、追加のインテントを共有 =
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;
}
}
Lollipop（21）では、Intent.EXTRA_REPLACEMENT_EXTRAS特定のアプリのインテントをオーバーライドします。
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);
}

私のアプリでは、Facebook SDKを統合して、ユーザーが自分のウォールで引用[事前入力テキスト]を共有できるようにしました。 FB SDKを使用して、これを行うことができます。それは私のアプリで動作し、同じものを使用している5K以上のユーザーがいます。
どうやらこれが機能しなかった警告や問題がなかったので、これはFBのポリシーに反しないようです。
