Flutter 应用程序在集成原生 android sdk 后卡在黑屏

如何解决Flutter 应用程序在集成原生 android sdk 后卡在黑屏

我有一个版本为 2.2.3 的 Flutter 应用程序，我最近使用平台通道方法将本机 SDK 集成到其中。出于某种原因，执行此操作后，每当我在模拟器或实际设备上运行 Flutter 应用程序时，它就会开始显示黑屏。该应用程序卡在黑屏上，不会继续显示主屏幕。这是我的主文件代码：

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  InAppPurchaseandroidPlatformAddition.enablePendingPurchases();

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  final Future<FirebaseApp> _initialization = Firebase.initializeApp();

  @override
  Widget build(BuildContext context) {
    SystemChrome.setEnabledsystemUIOverlays([]);
    SystemChrome.setPreferredOrientations(
        [DeviceOrientation.portraitUp,DeviceOrientation.portraitDown]);
    print('Inside main.dart build method');
    return FutureBuilder(
        future: _initialization,builder: (context2,snapshot) {
          if (snapshot.hasError) {
            NetworkErr();
            return Container();
          } else if (snapshot.connectionState == ConnectionState.done) {
            return MultiProvider(
              providers: [
                ChangeNotifierProvider(
                  create: (ctx) => ClueList(),),ChangeNotifierProvider(
                  create: (ctx) => score(),ChangeNotifierProvider(
                  create: (ctx) => Auth(),ChangeNotifierProvider(
                  create: (ctx) => Badges(),],child: MaterialApp(
                theme: ThemeData(
                    primarySwatch: Colors.teal,// primaryColor: Color.fromARGB(150,35,152,159,primaryColorLight: Color.fromARGB(
                      80,accentColor: Color.fromARGB(255,255,185,36),textTheme: ThemeData.light().textTheme.copyWith(
                            bodyText2: TextStyle(
                          fontFamily: 'Happy School',fontSize: 20,))),home: HomeScreen(),

在 MainActivity.java 文件中，我集成了本地 sdk，其中我调用从 Yodo1 MAS 检索广告下面是 MainActivity.java 文件中的代码。

package com.example.xxxxx;

import android.content.Intent;
import android.os.Bundle;

import androidx.annotation.NonNull;

import com.yodo1.mas.Yodo1Mas;
import com.yodo1.mas.error.Yodo1MasError;
import com.yodo1.mas.event.Yodo1MasAdEvent;

import io.Flutter.app.FlutterActivity;
import io.Flutter.embedding.engine.FlutterEngine;
import io.Flutter.plugin.common.MethodCall;
import io.Flutter.plugin.common.MethodCall;
import io.Flutter.plugin.common.MethodChannel;
import io.Flutter.plugin.common.MethodChannel.Result;
import io.Flutter.plugin.common.MethodChannel.MethodCallHandler;
import io.Flutter.plugins.GeneratedpluginRegistrant;

public class MainActivity extends FlutterActivity {

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        System.out.println("before Calling MAS Get Instance");

        Yodo1Mas.getInstance().init(this,"xxxxxxxxx",new Yodo1Mas.InitListener() {
            @Override
            public void onMasInitSuccessful() {
             System.out.println("MAS Init Successful");

            }

            @Override
            public void onMasInitFailed(@NonNull Yodo1MasError error) {

            }
        });
        new MethodChannel(getFlutterView(),"com.examples.xxxxxx/yodo1").setMethodCallHandler(
            new MethodCallHandler() {
                @Override
                public void onMethodCall(MethodCall call,Result result) {
                    if (call.method.equals("getBannerAd")) {
                        System.out.println("RADHA LOading Banner Ad");
                        getBannerAd();

                    }
                }
            }
        );
        
    }

    private void getBannerAd() {

        int align = Yodo1Mas.BannerTop | Yodo1Mas.BannerHorizontalCenter;

        boolean isLoaded = Yodo1Mas.getInstance().isBannerAdLoaded();
        
            if (isLoaded) {
            Yodo1Mas.getInstance().showBannerAd(MainActivity.this,align);
            Yodo1Mas.getInstance().setBannerListener(new Yodo1Mas.BannerListener() {
            @Override
            public void onAdOpened(@NonNull Yodo1MasAdEvent event) {
            }

            @Override
            public void onAdError(@NonNull Yodo1MasAdEvent event,@NonNull Yodo1MasError error) {

            }

            @Override
            public void onAdClosed(@NonNull Yodo1MasAdEvent event) {

            }
        }    
        );
    }
    }
}

这是我的 AndroidManifest.xml

</manifest>

我还尝试了以下方法：

我跑了Flutter pub cache repair
我的原始项目是 Flutter + Kotlin 项目。由于集成本机 sdk 的代码仅在 Java 中可用，因此我通过将文件夹结构从 src/main/kotlin 移动到 src/main/java 将项目转换为 Java 项目，如下所述： Convert an existing Flutter Kotlin project to Flutter Java project

我已经坚持了 3 天多了。我搜索了几乎所有我在 SOF 上找到的黑屏解决方案，但无济于事。如果您有任何其他建议，请告诉我。谢谢。
