ParseServer LiveQuery无法在Android上运行

问题描述

我成功设置了ParseServer和Android SDK，并且可以与数据库之间收发对象。现在，我想使用LiveQuery，我集成了SDK，并按照了教程（https://github.com/parse-community/ParseLiveQuery-Android）进行操作，但是以某种方式无法正常工作。有人可以帮我找到错误吗？

MainActviity：

import android.os.Bundle
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import com.parse.Parse
import com.parse.ParSEObject
import com.parse.ParseQuery
import com.parse.livequery.ParseLiveQueryClient
import com.parse.livequery.SubscriptionHandling
import kotlinx.android.synthetic.main.activity_main.*


class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    Parse.initialize(Parse.Configuration.Builder(this)
        .applicationId("myId")
        .server("http://192.168.178.84:1337/parse/")
        .build())

    // Build Live Query Client
    val parseLiveQueryClient = ParseLiveQueryClient.Factory.getClient()

    // Build Query
    val parseQuery = ParseQuery.getQuery<ParSEObject>("Gamescore")

    // Build Live Query Listener
    val subscriptionHandling: SubscriptionHandling<ParSEObject> = parseLiveQueryClient.subscribe(parseQuery)
    subscriptionHandling.handleSubscribe {
        Toast.makeText(this,"Subscribed",Toast.LENGTH_LONG).show()
    }
    subscriptionHandling.handleEvents { query,event,data ->
        print(event)
    }
    subscriptionHandling.handleError { query,exception ->
        print(exception)
    }



    /*
    This is working fine,means the app can connect to my server
    */
    getData.setonClickListener {
        val query = ParseQuery.getQuery<ParSEObject>("Gamescore")
        query.getInBackground(
            "U8E8PFI7RG"
        ) { data,e ->
            if (e == null) {
                textViewName.text = data.getString("playerName")
                textViewscore.text = data.getInt("score").toString()
                textViewCheatMode.text = data.objectId.toString()
            } else {
                print(e)
            }
        }

    }
}
}

build.gradle（应用程序）-依赖项

dependencies {
implementation filetree(dir: "libs",include: ["*.jar"])
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.3.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

// Parse Server
implementation "com.github.parse-community.Parse-SDK-Android:parse:1.25.0"

// Parse Server Live Query
implementation 'com.github.parse-community:ParseLiveQuery-Android:1.2.2'

}

既不显示烤面包，也没有其他subscribtionHandling事件发生反应

编辑：我在Ubuntu 18.04上安装了parse-server和parse-dashboard以及mongodb，并使用Android Studio作为客户端通过应用程序连接到数据库
