package com.core; 

    import android.content.Intent; 
    import android.os.Bundle; 
    import android.view.Window; 
    import android.widget.Toast;

    import com.minoritybiz.facebooks.SimpleFacebook; 
    import com.minoritybiz.facebooks.SimpleFacebookConfiguration; 

    public class FacebookShareActivity extends BaseActivity {

      simpleFacebookConfiguration = simpleFacebookConfigurationBuilder.build(); 
      SimpleFacebook.setConfiguration(simpleFacebookConfiguration); 
      getIntentData(); 
      if (simpleFacebook.isLogin()) { 
       publishFeed(); 
      } else {

        .setMessage(shareLabel).build(); 
      simpleFacebook.publish(feed, new onPublishListener());

     class OnLoginListener implements SimpleFacebook.OnLoginListener { 

      @Override

      @Override

      @Override 
      public void onFail(String reason) { 
       Toast.makeText(FacebookShareActivity.this, "Failure", Toast.LENGTH_LONG).show(); 
      } 
     } 

     class onPublishListener implements SimpleFacebook.OnPublishListener { 

      @Override 
      public void onComplete(String id) { 
       hideProgressDialog(); 
       Toast.makeText(FacebookShareActivity.this, "Posted Successfully...", Toast.LENGTH_LONG).show(); 
       finish(); 
      } 

      @Override

当家picture不会工作，你必须给一些link也。它的逻辑权利？

虽然张贴饲料，如果你想添加的图片必须有一些链接，并与它相关递减/标题（可选）。由于Feed中的图片与您共享的链接相关联。这里有一个饲料的外观喜欢 -

如果仅想发布一个光电，这不是一个饲料;您应该使用/photos API来发布照片。

因此，将picture和link添加到参数中，否则更改API。
