Share Text on Facebook from Android App via ACTION

2018-12-31 21:32发布

I have an Android app and it supports sending text via other apps. It therefore uses the ACTION_SEND intent and the EXTRA_TEXT field. The chooser presents me with all apps that can handle such an intent. Those are Twitter, EMail, ... and Facebook. But when I select Facebook it opens the browser and goes to the following page:

http://m.facebook.com/sharer.php?u=mytext

It shows my text and the submit button. But when I press the submit button nothing happends. The page just loads again. I think maybe it is only possible to send URLs via the Facebook App. Could that be?

Did anyone manage to send text via ACTION_SEND through the Facebook Android app?

So I have a work around, but it assumes you have control over the page you're sharing...

If you format your EXTRA_TEXT like so...

String myText = "Hey!\nThis is a neat pic!";
String extraText = "http://www.example.com/myPicPage.html?extraText=\n\n" + myText;

... then on non-Facebook apps, your text should appear something like this:

http://www.example.com/myPicPage.html?extraText=

Hey!
This is a neat pic!

Now if you update your website such that requests with the extraText query parameter return the contents of extraText in the page's meta data.

<!-- Make sure to sanitize your inputs! e.g. http://xkcd.com/327/ -->
<meta name="title" content="Hey! this is a neat pic!">

Then when Facebook escapes that url to generate the dialog, it'll read the title meta data and embed it into your share dialog.

I realize this is a pretty yuck solution, so take with a grain of salt...

  • This is a bug from Facebook, not your code
  • Facebook will NOT fix this bug, they say it is "by design" that they broke the Android share system : https://developers.facebook.com/bugs/332619626816423
  • use the SDK or share only URL.
  • Tips: you could cheat a little using the web page title as text for the post.

First you need query Intent to handler sharing option. Then use package name to filter Intent then we will have only one Intent that handler sharing option!

Share via Facebook

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Content to share");
PackageManager pm = v.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList) {
    if ((app.activityInfo.name).contains("facebook")) {
        final ActivityInfo activity = app.activityInfo;
        final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);
        shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |             Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
        shareIntent.setComponent(name);
        v.getContext().startActivity(shareIntent);
        break;
   }
}

Bonus - Share via Twitter

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Content to share");
PackageManager pm = v.getContext().getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList) {
    if ("com.twitter.android.PostActivity".equals(app.activityInfo.name)) {
        final ActivityInfo activity = app.activityInfo;
        final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name);
        shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |             Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
        shareIntent.setComponent(name);
        v.getContext().startActivity(shareIntent);
        break;
   }
}

To make the Share work with the facebook app, you only need to have suply at least one link:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Wonderful search engine http://www.google.fr/");
startActivity(Intent.createChooser(intent, "Share with"));

This will show the correct sharing window but when you click on share, nothing happends (I also tried with the official Twitter App, it does not work).

The only way I found to make the Facebook app sharing work is to share only a link with no text:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "http://www.google.fr/");
startActivity(Intent.createChooser(intent, "Share with"));

It will show the following window and the Share button will work:

facebook share

Apparently it automatically takes an image and text from the link to populate the share.

If you want to share only text, you will have to use the facebook api: https://github.com/facebook/facebook-android-sdk

EDITED: with the new release of the official Facebook app for Android (July 14 2011) IT WORKS!!!

OLD: The examples above do not work if the user chooses the Facebook app for sharing, but they do work if the user chooses the Seesmic app to post to Facebook. I guess Seesmic have a better implementation of the Facebook API than Facebook!
