android - 如何使用 android 在 Facebook 中授予 publish_action 权限

Question

我遇到了错误

java.lang.UnsupportedOperationException: Session: an attempt was made to request new permissions for a session that has a pending request.

以下是我的代码，

    public class MainActivity extends Activity  {

    private static final String TAG = "MainFragment";
    private UiLifecycleHelper uiHelper;
    WebView webView;
    Button nextButton;
    LoginButton authButton;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        authButton = (LoginButton) findViewById(R.id.authButton);

        authButton.setReadPermissions(Arrays.asList("email","user_birthday","basic_info"));

        uiHelper = new UiLifecycleHelper(this, callback);
        uiHelper.onCreate(savedInstanceState);

    }    

    private void onSessionStateChange(final Session session,
            SessionState state, Exception exception) {

在您的 Activity 中使用此代码。

authButton.setPublishPermissions("publish_actions", "email",
            "user_birthday", "basic_info");
