java - {Facebook 登录} java.lang.NoClassDefFoundError : android. support.v4.content.LocalBroadcastManager

Question

我非常关注 this guide然而，从字面上看，当应用程序启动并且应该创建 Facebook session 时，应用程序崩溃了。我认为这些库未包含在构建中...

package com.firstandroidapp;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.widget.TextView;
import com.facebook.*;
import com.facebook.model.*;

public class MainActivity extends Activity {

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

    // start Facebook Login
    Session.openActiveSession(this, true, new Session.StatusCallback() {

      // callback when session changes state
      @Override
      public void call(Session session, SessionState state, Exception exception) {
        if (session.isOpened()) {

          // make request to the /me API
          Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {

            // callback after Graph API response with user object
            @Override
            public void onCompleted(GraphUser user, Response response) {
              if (user != null) {
                TextView welcome = (TextView) findViewById(R.id.welcome);
                welcome.setText("Hello " + user.getName() + "!");
              }
            }
          });
        }
      }
    });
  }

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

}

这是异常堆栈:

Answer 1

只是替换

     YourProject\lib\android-support-v4.jar 

与

     facebook-android-sdk-x.xx.x\libs\android-support-v4.jar 

其中 x.xx.x 是 facebook sdk 版本，例如3.21.0
