如果在模拟器上安装了Facebook应用，则无法登录到Facebook-Android 4.3

Question

I have been banging my head on this problem for a while now. I know there are other posts of a similar fashion but I cant seem to get anything to work. I have the issue where if the Facebook app is on the emulator it will not login properly.

What happens is when a user will hit the login button a small dialog will pop up and ask them if the app can get these things(permissions) from them. You hit OK and it brings you back and nothing is changed....

I look at my LOGCAT and see that it repeatedly says: Logged Out (two times) every time you hit the button.

Logging in works if FB is not installed on the emulator.

Here is my code:

FBInit - Fragment Activity Handler:

public class FBInit extends FragmentActivity {

private FBInitFragment fbInitFrag;


@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fbinit);

    final ActionBar actionBar = getActionBar();
    actionBar.hide();

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

    findViewById(R.id.fb_init_next).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent returnIntent = new Intent();
            returnIntent.putExtra("result", 1);
            setResult(RESULT_OK, returnIntent);
            finish();
        }
    });
    findViewById(R.id.fb_init_back).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent returnIntent = new Intent();
            returnIntent.putExtra("result", 1);
            setResult(RESULT_CANCELED, returnIntent);
            finish();
        }
    });

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.fbinit, menu);
    return true;
}



}

FBInitFragment :

public class FBInitFragment extends Fragment {

private static final String TAG = "FBInitFragment";

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.activity_fbinit, container, false);

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

    return view;
}

private final 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()) {
        Log.i(TAG, "Logged in...");
    } else if (state.isClosed()) {
        Log.i(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);
}
}

Please advise!!

Thanks

This means your key hashes are incorrectly set in your app settings.

Please see this section on getting your key hashes and setting them correctly: https://developers.facebook.com/docs/android/getting-started/facebook-sdk-for-android/#create-app
