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 集成到该应用程序中。出于某种原因，当我在模拟器或实际设备上运行时，我的 Flutter 应用程序开始显示黑屏。该应用程序卡在黑屏上，无法继续显示主屏幕。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,
35,
152,
159,
),
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，我集成了本机 sdk，我在其中调用以从 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

我还尝试了以下方法：
- 我跑了
flutter pub cache repair - 我最初的项目是 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颤振Java项目
我已经坚持了3天多了。我搜索了几乎所有在 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。
