我正在尝试在 Android 应用程序中获得我的阅读和发布权限，它第一次在网络对话框中完美运行。下一次授权成功后，它说你已经授权了两次对话。

这是创建会话对象的代码。

Session session = Session.getActiveSession();
                if(session == null){
                    session = new Session.Builder(HomeActivity.this).setApplicationId(MyTouchTunesApplication.getSettings().getFacebookAppId()).build();
                    Session.setActiveSession(session);
                }else{
                    Util.clearFacebookToken();
                 }
                if(!session.isOpened() && !session.isClosed()){
                    ArrayList<String> permissions = new  ArrayList<String>();
                    permissions.add("email");
                    session.openForRead(new Session.OpenRequest(HomeActivity.this).setCallback(statusCallback).setPermissions(permissions));
                }else{
                    Session.setApplicationId(MyTouchTunesApplication.getSettings().getFacebookAppId());
                    Session.openActiveSession(HomeActivity.this, true, statusCallback);
                }

我的回调方法

public void call(Session session, SessionState state, Exception exception) {
        Log.d("session state", state.toString());
        if(exception != null){
            if(!exception.getMessage().contains("user")){
                showError(exception.getMessage());
                return;
            }
        }
        if(session.isOpened() && state == SessionState.OPENED && !session.getPermissions().contains("publish_stream")){
            final String[] PERMISSION_ARRAY_PUBLISH = {"publish_stream"};
            final List<String> permissionList = Arrays.asList(PERMISSION_ARRAY_PUBLISH);
            session.requestNewPublishPermissions(new NewPermissionsRequest(HomeActivity.this,permissionList ));
            return;
        }
        if(session !=null && session.isOpened() && state == SessionState.OPENED_TOKEN_UPDATED){
            mLoginCommand = new LoginCommand(HomeActivity.this, fbloginHandler, null, null, session.getAccessToken(), String.valueOf(session.getExpirationDate().getTime()));
            mLoginCommand.execute();
        }
    }

当用户在授权应用程序后登录时，我没有获得所有权限，它只返回电子邮件权限，这就是为什么我的情况在 Statuscallback 中被打破。我必须收到电子邮件并一一发布，当用户发布状态时不能这样做。我对此实施表示怀疑，希望对此有所帮助

谢谢。

我已经实现了这样，它的工作原理。

private void doSocialNetworkinWithFacebook()
    {
        // check for session 
         Session session=Session.getActiveSession();
         if (session != null && session.isOpened()) 
             {  
                // user is already login show
                    try
                        {
                            Session.OpenRequest request = new Session.OpenRequest(this);
                            request.setPermissions(Arrays.asList("email", "publish_actions"));
                        }
                    catch (Exception e)
                        {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                 Request.executeMeRequestAsync(session, new Request.GraphUserCallback() 
                        {

将创建会话代码中的第二个 if-else 条件替换为以下条件：

        if (!session.isOpened() && !session.isClosed()) {
             Session.OpenRequest request = new Session.OpenRequest(this);
                request.setPermissions(Arrays.asList("email", "publish_actions"));
                request.setCallback(statusCallback);
                session.openForPublish(request);
           }else{
                Session.setApplicationId(MyTouchTunesApplication.getSettings().getFacebookAppId());
                Session.openActiveSession(HomeActivity.this, true, statusCallback);
            }

它现在应该可以工作了。
