当Facebook应用程序安装时，Android和Facebook登录不起作用

我正在开发一个应该与Facebook连接的应用程序，我遵循facebook教程并在Facebook仪表板中插入了散列键。当Facebook应用程序安装时，Android和Facebook登录不起作用

我能够与Facebook连接，但是当安装Facebook应用程序时我无法再与Facebook连接，会话状态已关闭。

我读了几个主题，但我找不到对我的问题有好处的解决方案，因此我决定发布我的问题，您有什么想法关注我的问题吗？

继我的源代码

public class FragmentSn extends Fragment { 

private static final String TAG = "FragmentSn"; 
private UiLifecycleHelper uiHelper; 
static boolean fbLoggedIn; 



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

    LoginButton authButton = (LoginButton) rootView.findViewById(R.id.authButton); 
    authButton.setReadPermissions(Arrays.asList("basic_info", "email")); 
    authButton.setFragment(this); 

    return rootView; 
} 

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

@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, 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 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); 
} 

private Session.StatusCallback callback = new Session.StatusCallback() { 

    @Override 
    public void call(Session session, SessionState state, Exception exception) { 
     onSessionStateChange(session, state, exception); 
    } 
}; 

private void onSessionStateChange(Session session, SessionState state, Exception exception) { 
    if (state.isOpened()) { 
     fbLoggedIn=true; 
    } else if (state.isClosed()) { 
     fbLoggedIn=false; 
    } 
} 
}

MainActivity源代码

public class MainActivity extends ActionBarActivity { 

// Declare Tab Variable 
ActionBar.Tab Tab1, Tab2, Tab3,Tab4; 
Fragment fragmentMap = new FragmentMap(); 
Fragment fragmentCoupon = new FragmentCoupon(); 
Fragment fragmentCampaign = new FragmentCampaign(); 
Fragment fragmentSn = new FragmentSn(); 
Tools tools; 

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

    ActionBar actionBar = getSupportActionBar(); 
    // Hide Actionbar Icon 
    actionBar.setDisplayShowHomeEnabled(false); 

    // Hide Actionbar Title 
    actionBar.setDisplayShowTitleEnabled(false); 

    // Create Actionbar Tabs 
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

    // Set Tab Icon and Titles 
    Tab1 = actionBar.newTab().setIcon(this.getResources().getDrawable(R.drawable.tab_map)); 
    Tab2 = actionBar.newTab().setIcon(this.getResources().getDrawable(R.drawable.tab_coupon)); 
    Tab3 = actionBar.newTab().setIcon(this.getResources().getDrawable(R.drawable.tab_campaign)); 
    //Tab4 = actionBar.newTab().setIcon(this.getResources().getDrawable(R.drawable.tab_sn)); 

    // Set Tab Listeners 
    Tab1.setTabListener(new TabListener(fragmentMap)); 
    Tab2.setTabListener(new TabListener(fragmentCoupon)); 
    Tab3.setTabListener(new TabListener(fragmentCampaign)); 
    //Tab4.setTabListener(new TabListener(fragmentSn)); 

    // Add tabs to actionbar 
    actionBar.addTab(Tab1); 
    actionBar.addTab(Tab2); 
    actionBar.addTab(Tab3); 
    //actionBar.addTab(Tab4); 

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

    // AM 2014/01/15 - START 
    //Check update information 
    tools = new Tools(this.getApplicationContext()); 
    // AM 2014/01/15 - END 

} 




@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu items for use in the action bar 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.main, menu); 
    return super.onCreateOptionsMenu(menu); 
} 

}

期待您的回复，谢谢

https://developers.facebook.com/docs/android/login-with-facebook/将你的散列键与给定的代码相匹配以生成散列键programmactily是否相同 –

感谢chintan的回复，但不幸的是我检查了hask键更多时间和它匹配。 –

有默认的登录例子，只需下载最新的sdk并尝试使用它。 –
