我正在使用以下代码登录 Facebook。此登录过程在调试时有效，但不适用于已签名的应用程序。我在 Facebook 应用程序设置中添加了调试哈希键和释放哈希键，但没有任何成功。知道是什么原因造成的吗？

package com.priyank.safeboard;

import java.util.Arrays;

import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

import com.actionbarsherlock.app.SherlockFragment;
import com.facebook.Session;
import com.facebook.SessionState;
import com.facebook.UiLifecycleHelper;
import com.facebook.widget.LoginButton;

public class MainFragment extends SherlockFragment {

    private static final String TAG = "MainFragment";
    private UiLifecycleHelper uiHelper;
    Button b;
    LoginButton authButton;

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

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


        /*b=(Button) view.findViewById(R.id.button1);
        b.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
              updateDetail();
            }
          });*/

        authButton.setReadPermissions(Arrays.asList("user_location", "user_birthday","user_likes", "user_status"));

        return view;
    }
    protected void updateDetail() {


        Intent intent = new Intent();
        intent.setClass(getActivity(), MainActivity.class);

        startActivity(intent);


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


    }
    @Override
    public void onResume() {
        super.onResume();
        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);
    }
    private void onSessionStateChange(Session session, SessionState state, Exception exception) {
        if (state.isOpened()) {
            updateDetail();
            authButton.setVisibility(View.INVISIBLE);
            //b.setVisibility(View.VISIBLE);
            Log.i(TAG, "Logged in...");
        } else if (state.isClosed()) {
            Log.i(TAG, "Logged out...");
        }
    }

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

}

我在 log cat 中调试应用程序时使用以下代码获取应用程序的密钥哈希，但是如何获取签名应用程序的“密钥哈希”？

try {
        PackageInfo info = getPackageManager().getPackageInfo(
                "Your package name", 
                PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.d("Your Tag", Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
    } catch (NameNotFoundException e) {

    } catch (NoSuchAlgorithmException e) {

    }

您唯一要更改的是 iz 应用程序签名，因此很明显有一些带有哈希的东西。Facebook 在他们的页面上给出了错误的哈希计算方法。今天我也遇到了这个问题 - 这个解决方案：使用 facebook sdk 为应用程序生成哈希密钥对我来说没问题。
