Android share intent for Facebook

问题:

I have some problem with below code. This code is working for email, message, Twitter (for sending the text) but not for Facebook. Why?

Intent i=new Intent(android.content.Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(android.content.Intent.EXTRA_SUBJECT,"ScribeAir");
i.putExtra(android.content.Intent.EXTRA_TEXT, "ScribeAir has some cool features. Just use it...");
startActivity(Intent.createChooser(i,"Share"));

this is not working for facebook because Facebook can share only a link via ACTION_SEND. if U want to send Text As well as link.

Firstly you have to get the list of installed application that support ACTION_SEND then buil a dialog

  Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    List activities = getPackageManager().queryIntentActivities(sharingIntent,0);

after the activities now build a dialog to show activities .then get the intent for facebook and share it with facebook api all other to be handled by itself but please pass the class name for other activities.

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
                sharingIntent.setClassName(,);
                sharingIntent.setType("text/plain");
                sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"hello");
                sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "facebook");

Answering to question which is asked long long time ago..

As of i know, Facebook does not allow the Pre-populating of text through Intent unlike in the Twitter / Email. It by Facebook Default. But with the help of Facebook SDK, we can able to share text in the form of link.

Refer Facebook SDK sharing Docs
