java.lang.NoClassDefFoundError：android.support.v4.content.LocalBroadcastManager facebook android app

我知道这个问题已经被问到,我已经尝试使用许多其他的帖子来帮助我,但没有一个工作.我正在通过这个链接安装Facebook登录到 Android应用程序： https://developers.facebook.com/docs/android/getting-started.我导入了Facebook SDK,它适用于示例应用程序,所以我知道这是确定.我的libs文件夹中没有任何JAR.在属性> Android库我已经添加了appcompat_v7和FacebookSDK.在建路径>订单和导出我已经检查了Android依赖关系和Android私有库.

错误

java.lang.NoClassDefFoundError：android.support.v4.content.LocalbroadcastManager

发生在这一行代码：

Session.openActiveSession(this,true,new Session.StatusCallback(){

任何关于为什么会发生这样的想法？我一整天都在和我的房产混乱,不能让它工作.代码就在FB开发者网站上,所以我确定它的罚款.谢谢.

完整活动：

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,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.newMeRequest(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() + "!");
          }
        }
      }).executeAsync();
    }
  }
});
}

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

}

编辑

只是给你们一个视觉的我的设置的样子：

解决方法

根据我的经验,这种错误发生在构建设置中.

我建议做如下.

点击按钮“添加罐子…”

选择“android-support-v4.jar”

选择“订单和导出”选项卡,并选中“android-support-v4.jar”.

清理项目并构建.

运行项目后,应用程序将执行.

祝你好运
