登錄使用Facebook的SDK不工作

我試圖使用集成Facebook登錄>的Facebook SDK LoginUsingLoginFragmentActivity登錄使用Facebook的SDK不工作

這是給我的錯誤：

MainActivityCode：

public class LoginActivity extends Activity { 

    private Button mFacebookLogin; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.layout_login); 

     mFacebookLogin = (Button) findViewById(R.id.btnFacebookLogin); 
     mFacebookLogin.setOnClickListener(mOnClickListener); 
    } 

    private OnClickListener mOnClickListener = new OnClickListener() { 

     @Override 
     public void onClick(View view) { 
      switch (view.getId()) { 
      case R.id.btnFacebookLogin: 
       Intent intent = new Intent(LoginActivity.this, LoginIntoFacebookActivity.class); 
       startActivity(intent); 
       break; 

      default: 
       break; 
      } 
     } 
    }; 

}

LoginIntoFacebookActivity。 java

public class LoginIntoFacebookActivity extends FragmentActivity { 

    private UserSettingsFragment userSettingsFragment; 

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

     setContentView(R.layout.login_fragment_activity); 

     FragmentManager fragmentManager = getSupportFragmentManager(); 
     userSettingsFragment = (UserSettingsFragment) fragmentManager.findFragmentById(R.id.login_fragment); 
     userSettingsFragment.setSessionStatusCallback(new Session.StatusCallback() { 
      @Override 
      public void call(Session session, SessionState state, Exception exception) { 
       Log.d("LoginUsingLoginFragmentActivity", String.format("New session state: %s", state.toString())); 
      } 
     }); 
    } 

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

}

錯誤跟蹤：

您是否在AndroidManifest.xml中添加了Facebook登錄活動？ –

@Haresh問題已更新，清單文件已添加 – reiley

好的讓我檢查 –

我使用此代碼，並能正常工作，請檢查出來。

if (facebook.getAccessToken() != null) { 

      //user got logged in do you code here is 

     } else { 
      loginToFacebook();//user is not login force user to first complete the login 

      } 

public void loginToFacebook() { 

    mPrefs = getPreferences(MODE_PRIVATE); 
    String access_token = mPrefs.getString("access_token", null); 
    long expires = mPrefs.getLong("access_expires", 0); 

    if (access_token != null) { 
     facebook.setAccessToken(access_token); 

     Log.d("FB Sessions", "" + facebook.isSessionValid()); 
    } 

    if (expires != 0) { 
     facebook.setAccessExpires(expires); 
    } 

    if (!facebook.isSessionValid()) { 
     facebook.authorize(this, 
       new String[] { "email", "publish_stream" }, 
       new DialogListener() { 

        @Override 
        public void onCancel() { 
         // Function to handle cancel event 
        } 

        @Override 
        public void onComplete(Bundle values) { 
         // Function to handle complete event 
         // Edit Preferences and update facebook acess_token 
         SharedPreferences.Editor editor = mPrefs.edit(); 
         editor.putString("access_token", 
           facebook.getAccessToken()); 
         editor.putLong("access_expires", 
           facebook.getAccessExpires()); 
         editor.commit(); 
         Toast.makeText(sms_by_id.this, 
           "Successfully Login", Toast.LENGTH_LONG) 
           .show(); 
         pwindo.dismiss(); 

         // Making Login button invisible 

        } 

        @Override 
        public void onError(DialogError error) { 
         // Function to handle error 

        } 

        @Override 
        public void onFacebookError(FacebookError fberror) { 
         // Function to handle Facebook errors 
         pwindo.dismiss(); 
         Toast.makeText(sms_by_id.this, "Facebook Error", 
           Toast.LENGTH_LONG).show(); 
        } 

       }); 
    } 
}

這可能是AndroidManifest文件有哪些包LoginIntoFacebookActivity屬於錯誤的信息 - 有你張貼的錯誤跟蹤和清單文件之間的不匹配。
