Android アプリケーションを使用して、自分のウォールにメッセージを投稿したいと考えています。ログインするためのメソッド loginToFacebook() があります。ボタンをクリックすると、ユーザーがログインしている場合、メッセージが投稿されます。私はFacebook APIにあまり詳しくないので、Facebook開発者のドキュメントやインターネット上の他のサイトを調べて、次のコードを提案しました。それでも、私のウォールにはメッセージが投稿されません。明らかに何かが欠けていますが、LogCat にエラーがないため、何がわかりません。

public class ShareActivity extends Activity implements OnClickListener{
    Facebook facebook = new Facebook("477110419013909");
    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
    String FILENAME = "AndroidSSO_data";
    SharedPreferences mPrefs;


  public void onClick(View arg0) {
        loginToFacebook();
        if (facebook.isSessionValid()) {
            Bundle bundle = new Bundle();
            bundle.putString("message","Hey Facebook!");
            try {
                String strRet = facebook.request("/me/feed",bundle,"POST");
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                Log.e("Facebook", "Error: " + e.getMessage());
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                Log.e("Facebook", "Error: " + e.getMessage());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                Log.e("Facebook", "Error: " + e.getMessage());
            }

}

public void loginToFacebook() {
    mPrefs = getPreferences(MODE_PRIVATE);
    String access_token = mPrefs.getString("access_token", null);
    long expires = mPrefs.getLong("access_expires", 0);

    if (access_token != null) {
        facebook.setAccessToken(access_token);
    }

    if (expires != 0) {
        facebook.setAccessExpires(expires);
    }

    if (!facebook.isSessionValid()) {
        facebook.authorize(this,
                new String[] { "email", "publish_stream" },
                new DialogListener() {

                    @Override
                    public void onCancel() {
                        // Function to handle cancel event
                    }

                    @Override
                    public void onComplete(Bundle values) {
                        // Function to handle complete event
                        // Edit Preferences and update facebook acess_token
                        SharedPreferences.Editor editor = mPrefs.edit();
                        editor.putString("access_token",
                                facebook.getAccessToken());
                        editor.putLong("access_expires",
                                facebook.getAccessExpires());
                        editor.commit();
                    }

                    @Override
                    public void onError(DialogError error) {
                        // Function to handle error

                    }

                    @Override
                    public void onFacebookError(FacebookError fberror) {
                        // Function to handle Facebook errors

                    }

                });
    }
}
}

やってみました

if (facebook.isSessionValid()) {
            Bundle bundle = new Bundle();
            bundle.putString("message","Hey Facebook!");

            facebook.dialog((Activity) this, "feed", bundle,
                    new DialogListener() {

                        public void onComplete(Bundle values) {
                        }

                        public void onFacebookError(FacebookError error) {}
                        public void onError(DialogError e) {}
                        public void onCancel() {}
            });
 }

どちらも機能しませんでした

私はこのアクティビティクラスを投稿画像に使用しました：

public class PostStatusFBActivity extends Activity {
 private static String[] PERMISSIONS = 
            new String[] {"photo_upload","publish_stream"};

Bundle parems;
//String status;
private AsyncFacebookRunner mAsyncRunner;

@Override

    super.onCreate(savedInstanceState);

    mHandler = new Handler();

    Intent intent=getIntent();
    parems=intent.getBundleExtra("params");
    fb= new Facebook(PostStatusFBActivity.FB_APP_ID);

    SessionStore.restore(fb, this);

    if (fb.isSessionValid()) 
        post_status();
    else
        fb.authorize(this, PERMISSIONS,new AppLoginListener());

}

private class AppLoginListener implements DialogListener {

    public AppLoginListener() {

    }

    public void onCancel() {

        Toast.makeText(getApplicationContext(), "Please accept to login", Toast.LENGTH_LONG).show();

        mAsyncRunner=new AsyncFacebookRunner(fb);
        post_status();
    }

    public void onError(DialogError e) {
        Log.e("BTS", "dialog error: " , e);

    public void onFacebookError(FacebookError e) {

            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

}

これが前のアクティビティから渡したバンドルパラメータです byte[] data = null;
Bundle params = new Bundle();
params.putByteArray("photo", data); params.putString("caption", status);

バンドルに設定できるその他の値 params.putString("message", "This string will appear as the status message"); params.putString("link", "This is the URL to go to"); params.putString("name", "This will appear beside the picture"); params.putString("caption", "This will appear under the title"); params.putString("description", "This will appear under the caption"); params.putString("picture", "This is the image to appear in the post");
