我跟随official login tutorial,突然之间我遇到了错误。我是android的新手,所以我有点困惑。所以,这是我的FBMainFragment,如MainFragment官方教程:

public class FBMainFragment extends android.support.v4.app.Fragment {

private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

private UiLifecycleHelper uiHelper;

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

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.social_networks, container, false);

    LoginButton authButton = (LoginButton) view.findViewById(R.id.FB_Login);
    authButton.setFragment(this);

    return view;
}

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    if (state.isOpened()) {
        Log.i(MenuActivity.TAG, "Logged in...");
    } else if (state.isClosed()) {
        Log.i(MenuActivity.TAG, "Logged out...");
    }
}

@Override
public void onResume() {
    super.onResume();
    // For scenarios where the main activity is launched and user
    // session is not null, the session state change notification
    // may not be triggered. Trigger it if it's open/closed.
    Session session = Session.getActiveSession();
    if (session != null &&
            (session.isOpened() || session.isClosed()) ) {
        onSessionStateChange(session, session.getState(), null);
    }

    uiHelper.onResume();
}

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

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

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

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

...这里是我的SocialNetworksActivityMainActivity。文档:

public class SocialNetworksActivity extends FragmentActivity {

private FBMainFragment fbMainFragment;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState == null) {
        // Add the fragment on initial activity setup
        fbMainFragment = new FBMainFragment();
        getSupportFragmentManager()
                .beginTransaction()
                .add(android.R.id.content, fbMainFragment)
                .commit();
    } else {
        // Or set the fragment from restored state info
        fbMainFragment = (FBMainFragment) getSupportFragmentManager().findFragmentById(android.R.id.content);
    }
}

如您所见,我还没有完成教程。现在我在2部分的末尾。但是,正如它所说,构建并运行您的项目。使用Facebook登录。您应该通过权限屏幕。。所以我试着运行我的项目和我的应用程序只是觉得。有任何想法吗? ;)

我刚刚在清单中添加了此代码,现在一切正常。 @PankajNimgade,谢谢你的帮助。

<activity android:name="com.facebook.LoginActivity"
              android:theme="@android:style/Theme.Translucent.NoTitleBar"
              android:label="@string/app_name" />

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/FB_AppID"/>

P.S FB_AppID是我的Facebook应用ID
