使用Parse在Android中集成Facebook登录时出错

Question

您好，在我的项目中，我使用解析来存储用户登录信息，当我尝试集成Facebook登录信息时，我在此行的Application类中收到错误

ParseFacebookUtils.initialize(MyApplication.this);

，错误是......

java.lang.AbstractMethodError: abstract method "boolean com.parse.ParseAuthenticationProvider.restoreAuthentication(org.json.JSONObject)"
        at com.parse.ParseUser.synchronizeAuthData(ParseUser.java:1472)
        at com.parse.ParseUser.registerAuthenticationProvider(ParseUser.java:1525)
        at com.parse.ParseFacebookUtils.initialize(ParseFacebookUtils.java:95)
        at com.parse.ParseFacebookUtils.initialize(ParseFacebookUtils.java:79)
        at com.sanafoundation.sanjaym.app.MyApplication.onCreate(MyApplication.java:44)
        at android.app.Instrumentation.callApplicationOnCreate(Instrumentation.java:1034)

我的Application类是

public class MyApplication extends Application {

private static MyApplication mInstance;

@Override
public void onCreate() {
    super.onCreate();
    mInstance = this;

    // register with parse
    ParseUtils.registerParse(this);

    ParseUser.enableAutomaticUser();
    ParseACL defaultACL = new ParseACL();

    // If you would like all objects to be private by default, remove this line.
    defaultACL.setPublicReadAccess(true);
    ParseACL.setDefaultACL(defaultACL, true);

    Firebase.setAndroidContext(this);

    FacebookSdk.sdkInitialize(getApplicationContext());

    Parse.initialize(this,
            AppConfig.PARSE_APPLICATION_ID,
            AppConfig.PARSE_CLIENT_KEY
    );

    ParseFacebookUtils.initialize(MyApplication.this);

}

public static synchronized MyApplication getInstance() {
    return mInstance;
}

}

我也尝试在build.gradle文件中添加库路径，但它不起作用。有人能帮助我吗？
