通过 ACTION_SEND 从 Android 应用程序在 Facebook 上共享文本

It appears that the Facebook app handles this intent incorrectly. The most reliable way seems to be to use the Facebook API for Android.

The SDK is at this link: http://github.com/facebook/facebook-android-sdk

Under 'usage', there is this:

Display a Facebook dialog.

The SDK supports several WebView html dialogs for user interactions, such as creating a wall post. This is intended to provided quick Facebook functionality without having to implement a native Android UI and pass data to facebook directly though the APIs.

This seems like the best way to do it -- display a dialog that will post to the wall. The only issue is that they may have to log in first

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:

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!

It appears that it's a bug in the Facebook app that was reported in April 2011 and has still yet to be fixed by the Android Facebook developers.

The only work around for the moment is to use their SDK.

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;
}
}

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...

06/2013 :

• 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.

Check this out : By this we can check activity results also....
// Open all sharing option for user
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, ShortDesc+" from "+BusinessName);
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, ShortDesc+" "+ShareURL);
sharingIntent.putExtra(Intent.EXTRA_TITLE, ShortDesc+" "+ShareURL);
startActivityForResult(Intent.createChooser(sharingIntent, "Share via"),1000);
/**
* Get the result when we share any data to another activity
* */
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);


switch(requestCode) {
case 1000:
if(resultCode == RESULT_OK)
Toast.makeText(getApplicationContext(), "Activity 1 returned OK", Toast.LENGTH_LONG).show();
else
Toast.makeText(getApplicationContext(), "Activity 1 returned NOT OK", Toast.LENGTH_LONG).show();
break;
case 1002:
if(resultCode == RESULT_OK)
Toast.makeText(getApplicationContext(), "Activity 2 returned OK", Toast.LENGTH_LONG).show();
break;
}// end switch






}// end onActivityResult

if you want to show text put # at the begging of the message you want it will share it as Hashtag

ShareDialog shareDialog = new ShareDialog(this);
if(ShareDialog.canShow(ShareLinkContent.class)) {


ShareLinkContent linkContent = new ShareLinkContent.Builder().setContentTitle(strTitle).setContentDescription(strDescription)
.setContentUrl(Uri.parse(strNewsHtmlUrl))
.build();
shareDialog.show(linkContent);


}
