boton - Intento de compartir Android para Facebook: compartir texto Y enlace
compartir facebook android (5)
Acabo de construir este código y me funciona:
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);
}
}
Estoy tratando de usar el intento de compartir Android para publicar algo en Facebook. Se parece a esto:
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);
Entonces mi publicación tiene ambas: texto y un enlace. Pero cuando el mensaje se publica en Facebook, solo tiene el enlace, no hay mensaje. Probé varios extras pero nada funciona.
¿Alguien se enfrentó a este problema y lo resolvió? Tengo la aplicación de Facebook versión 1.8.1
Editar: Intenté eliminar el enlace, y la aplicación de Facebook no recibe mi mensaje (muestra un mensaje en blanco para ser publicado), pero no al revés. Parece que la aplicación está ignorando por completo los mensajes de texto sin formato. ¡Estoy asustado! ¿Es este un error importante en la aplicación fb que los mensajes de texto no se pueden publicar en absoluto (con intención de compartir)?
En Lollipop (21), puede usar Intent.EXTRA_REPLACEMENT_EXTRAS para anular la intención de aplicaciones específicas.
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);
}
En mi aplicación, he integrado Facebook SDK para permitir a los usuarios compartir la cita [texto precargado] en su muro. Usando FB SDK, es posible hacer esto. Funciona en mi aplicación y tengo más de 5 mil usuarios que usan la misma.
Aparentemente esto no va en contra de la política de FB ya que no he tenido ninguna advertencia o un problema donde esto no funcionó.
Los fragmentos de código para el mismo se pueden encontrar aquí,
Si vas a utilizar los Intentos de uso compartido de Android normales, desafortunadamente el intento de compartir Facebook solo puede tomar una sola URL (asegúrate de que tenga http: //) y ningún mensaje de texto adicional. Es una limitación extraña que realmente no tiene sentido.
Tienes que utilizar el SDK de Android oficial de Facebook en tu proyecto para obtener la funcionalidad de uso compartido completo. Que es trabajo extra
Corrí a problemas similares. Al final, lo que hice fue ramificar el intento. Si eligen compartir (en el intento regular de compartir con Android) a través de Facebook, crea una nueva intención de compartir que solo tiene la URL y envíala a Facebook. Todas las demás opciones de acciones (twitter, mensaje, correo electrónico) funcionarían de forma normal.
mi pregunta y solución están aquí:
Bifurcar los extras de Android Share Intent según el método que elijan compartir
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;
}
}
