ギャラリーから選択した画像をFacebookの壁面にAndroid appから投稿する方法は？

Question

自分のアンドロイドアプリから画像とテキストをFacebookの壁に投稿しようとしています。私はモバイルギャラリーから画像を選択する必要がありますが、動作しません。私はこのコードで何が問題になっているのかわかりません。誰も助けてくれますか？

public class PostFacebook extends Activity{ 
private Facebook mFacebook; 
private CheckBox mFacebookCb; 
private ProgressDialog mProgress; 
private static final int SELECT_PICTURE = 100; 
byte[] inputData; 
Uri selectedImageUri; 
String imgString; 
ImageView image; 
private Handler mRunOnUi = new Handler(); 

private static final String APP_ID = "7************"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.fbpost); 

    final EditText reviewEdit = (EditText) findViewById(R.id.revieew); 
    image = (ImageView) findViewById(R.id.imageView1); 
    mFacebookCb    = (CheckBox) findViewById(R.id.cb_facebook); 

    mProgress = new ProgressDialog(this); 

    mFacebook = new Facebook(APP_ID); 

    SessionStore.restore(mFacebook, this); 

    if (mFacebook.isSessionValid()) { 
     mFacebookCb.setChecked(true); 

     String name = SessionStore.getName(this); 
     name  = (name.equals("")) ? "Unknown" : name; 

     mFacebookCb.setText(" Facebook (" + name + ")"); 
    } 

    ((Button) findViewById(R.id.button1)).setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String review = reviewEdit.getText().toString(); 
      try { 
       InputStream iStream = getContentResolver().openInputStream(selectedImageUri); 
       inputData = GetImage.getBytes(iStream); 
       imgString = Base64.encodeToString(inputData, Base64.DEFAULT); 
       Log.v("image_check", imgString); 
       Toast.makeText(PostFacebook.this, imgString, Toast.LENGTH_SHORT).show(); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      if (review.equals("")) 
       return; 

      if (mFacebookCb.isChecked()) postToFacebook(review, imgString); 
     } 
    }); 
    image.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Intent intent = new Intent(); 
      intent.setType("image/*"); 
      intent.setAction(Intent.ACTION_GET_CONTENT); 
      startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE); 
     } 
    }); 
} 

private void postToFacebook(String review, String image) { 
    mProgress.setMessage("Posting ..."); 
    mProgress.show(); 

    AsyncFacebookRunner mAsyncFbRunner = new AsyncFacebookRunner(mFacebook); 

    Bundle params = new Bundle(); 
    params.putString("message", review); 
    params.putString("picture", image); 
    params.putString("name", "Hira Ghaffar"); 
    params.putString("caption", "Innovent.net"); 
    params.putString("description", "Innovent is an android app developed by iFish Technologies"); 
    mAsyncFbRunner.request("me/feed", params, "POST", new WallPostListener()); 
} 

private final class WallPostListener extends BaseRequestListener { 
    public void onComplete(final String response) { 
     mRunOnUi.post(new Runnable() { 
      @Override 
      public void run() { 
       mProgress.cancel(); 

       Toast.makeText(PostFacebook.this, "Posted to Facebook", Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 
} 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (resultCode == RESULT_OK) { 
      if (requestCode == SELECT_PICTURE) { 
       selectedImageUri = data.getData(); 
       if (null != selectedImageUri) { 
       image.setImageURI(selectedImageUri); 

       } 
      } 
     } 
} 
}
