Question

我有一个问题：我已经从Facebook sdk复制粘贴代码我试图与Facebook建立联系。它只是不起作用...... 我真的很沮丧，我不知道还能做些什么。请帮忙......谢谢！

Session.openActiveSession(this, true, new Session.StatusCallback() {
              // callback when session changes state
              @Override
              public void call(Session session, SessionState state, Exception exception) {
                if (session.isOpened()) {
                  Request.newMeRequest(session, new Request.GraphUserCallback() {

                    // callback after Graph API response with user object
                    @Override
                    public void onCompleted(GraphUser user, Response response) {
                      if (user != null) {
                          Toast.makeText(getApplicationContext(), "Hello " + user.getName() + "!", 1).show();
                      }
                    }
                  }).executeAsync();
                }
              }
            });
    @Override
      public void onActivityResult(int requestCode, int resultCode, Intent data) {
          super.onActivityResult(requestCode, resultCode, data);
          Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
      }

首先，非常感谢你＆＃34; da_st＆＃34; 问题是在keyhash不是正确的。所以如果有人在我的代码中使用了我的问题

    String TAG = "com.sromku.simple.fb.example";
        PackageInfo info = context.getPackageManager().getPackageInfo(TAG,
            PackageManager.GET_SIGNATURES);
        for (Signature signature: info.signatures)
        {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            String keyHash = Base64.encodeToString(md.digest(), Base64.DEFAULT);
            Log.d(TAG, "keyHash: " + keyHash);

为什么onCompleted不会在Facebook sdk 3.8 Android中调用
