android - Facebook 共享对话框中的错误

Question

我遇到了一个不同的错误。我尝试执行 Facebook 共享对话框，但是我在 logcat 中遇到了这个错误。

 10-17 15:44:39.026: E/AndroidRuntime(2534): com.facebook.FacebookException: Unable to create Intent; this likely means the Facebook app is not installed.

我不知道这是什么意思。我试图搜索它，但没有类似的实例。这是我的代码。

TabFour.java

public class TabFour extends Fragment {
private UiLifecycleHelper uiHelper;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.activity_tab_four, container, false);

    return rootView;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    uiHelper = new UiLifecycleHelper(getActivity(), callback);
    uiHelper.onCreate(savedInstanceState);

    OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
    action.setProperty("book", "https://example.com/book/Snow-Crash.html");

    @SuppressWarnings("deprecation")
    FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(getActivity(), action, "books.reads", "book")
            .build();
    uiHelper.trackPendingDialogCall(shareDialog.present());
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    uiHelper.onActivityResult(requestCode, resultCode, data, new FacebookDialog.Callback() {
        @Override
        public void onError(FacebookDialog.PendingCall pendingCall, Exception error, Bundle data) {
            Log.e("Activity", String.format("Error: %s", error.toString()));
        }

        @Override
        public void onComplete(FacebookDialog.PendingCall pendingCall, Bundle data) {
            Log.i("Activity", "Success!");
        }
    });
}



@Override
public void onResume() {
    super.onResume();
    uiHelper.onResume();
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    uiHelper.onSaveInstanceState(outState);
}

@Override
public void onPause() {
    super.onPause();
    uiHelper.onPause();
}

@Override
public void onDestroy() {
    super.onDestroy();
    uiHelper.onDestroy();
}
private Session.StatusCallback callback = new Session.StatusCallback() {


    @Override
    public void call(Session session, SessionState state,
            Exception exception) {
        // TODO Auto-generated method stub

    }
};

}

对于那些真正想为可能没有安装 Facebook 应用程序的用户构建应用程序的人，请确保在您的 ShareDialog 构建器 ( more info here ) 周围包含此检查:

if (FacebookDialog.canPresentShareDialog(getApplicationContext(), 
                                         FacebookDialog.ShareDialogFeature.SHARE_DIALOG)) {
    FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
            .setLink("https://developers.facebook.com/android")
            .build();
    uiHelper.trackPendingDialogCall(shareDialog.present());

}
