如何检查Post在Google Plus上成功共享

Question

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{  
     super.onActivityResult(requestCode, resultCode, data);
     if(requestCode==392 &&resultCode==RESULT_OK)
     { 
          System.out.println("Google+"); 
     } 
}

Intent shareIntent = ShareCompat.IntentBuilder.from(getActivity())
            .setText(". http://www.http://stackoverflow.com/")
            .setType("text/plain")
            .getIntent()
            .setPackage("com.google.android.apps.plus");

            startActivityForResult(shareIntent, 392);

我想检查是否已发布，如何检查用户是否成功发布或取消了共享。
