So I'm using google_mobile_ads插件版本0.12.1+1（这是目前最新的版本）。 我遇到了一个奇怪的错误，在过去的3天里，我尝试了很多方法来解决这个问题，但没有任何成功。 请注意，它是工作的，而且该应用程序已经运行了几个月，所以所有的AdMob凭证都是正确的，我已经重新检查了很多次。 所以我不知道到底发生了什么，但我没有其他地方可以找到解决方案，所以我终于在这里发布了一个问题。我希望有人能帮助我，给我指点一下。 当rewardedAd.load()被调用时，应用程序崩溃了，错误信息如下。 E/AndroidRuntime(27180): FATAL EXCEPTION: main E/AndroidRuntime(27180): Process: com.me.app, PID: 27180 E/AndroidRuntime(27180): java.lang.InstantiationError: com.google.android.gms.ads.rewarded.RewardedAd E/AndroidRuntime(27180): at io.flutter.plugins.googlemobileads.FlutterRewardedAd.createRewardedAd(FlutterRewardedAd.java:154) E/AndroidRuntime(27180): at io.flutter.plugins.googlemobileads.FlutterRewardedAd.load(FlutterRewardedAd.java:95) E/AndroidRuntime(27180): at io.flutter.plugins.googlemobileads.GoogleMobileAdsPlugin.onMethodCall(GoogleMobileAdsPlugin.java:330) E/AndroidRuntime(27180): at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.onMessage(MethodChannel.java:233) E/AndroidRuntime(27180): at io.flutter.embedding.engine.dart.DartMessenger.handleMessageFromDart(DartMessenger.java:85) E/AndroidRuntime(27180): at io.flutter.embedding.engine.FlutterJNI.handlePlatformMessage(FlutterJNI.java:818) E/AndroidRuntime(27180): at android.os.MessageQueue.nativePollOnce(Native Method) E/AndroidRuntime(27180): at android.os.MessageQueue.next(MessageQueue.java:336) E/AndroidRuntime(27180): at android.os.Looper.loop(Looper.java:197) E/AndroidRuntime(27180): at android.app.ActivityThread.main(ActivityThread.java:8167) E/AndroidRuntime(27180): at java.lang.reflect.Method.invoke(Native Method) E/AndroidRuntime(27180): at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:496) E/AndroidRuntime(27180): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1100) I/Process (27180): Sending signal. PID: 27180 SIG: 9 In my code:替换代码3】在main.dart中被调用，一旦初始化完成，RewardedAd就会像这样被初始化。 _rewardedAd = RewardedAd( adUnitId: AdManager.rewardedAdUnitId, listener: AdListener( onRewardedAdUserEarnedReward: (RewardedAd ad, RewardItem reward) { print('Rewarded Ad successful: $ad reward: $reward'); // Give reward to user }, onAdLoaded: (Ad ad) { setState(() { isAdsLoading = false; }); }, onAdFailedToLoad: (Ad ad, LoadAdError error) { print('Error Rewarded Video Ad failed to load: $error'); }, ), request: AdRequest()) ..load();如果我去掉..load()，它就不会崩溃，但它永远不会加载。再一次，这在以前是不会崩溃的。 我已经做了什么来解决这个问题。 I have rechecked all the credentials: App ID and Ad unit Id are all correct. Go through the documentations again to make sure my AndroidManifest.xml are correctly set. Tried both versions 0.12.1+1 (null safety) and 0.11.0+4 (this version is the one used for live version). Tried both debug and release mode. Tried both in Android Virtual Device and real device. There are many others that I don't remember anymore.注意：实时版本工作正常。我曾尝试将该应用程序上传到封闭测试版本，但它仍然崩溃了。 The flutter run --verbose这是一个很长的日志，所以我在这里只包括错误部分，但你可以阅读所有的full log here [ +35 ms] E/AndroidRuntime(31757): FATAL EXCEPTION: main [ ] E/AndroidRuntime(31757): Process: com.me.app, PID: 31757 [ ] E/AndroidRuntime(31757): java.lang.InstantiationError: com.google.android.gms.ads.rewarded.RewardedAd [ ] E/AndroidRuntime(31757): at io.flutter.plugins.googlemobileads.FlutterRewardedAd.createRewardedAd(FlutterRewardedAd.java:154) [ ] E/AndroidRuntime(31757): at io.flutter.plugins.googlemobileads.FlutterRewardedAd.load(FlutterRewardedAd.java:95) [ ] E/AndroidRuntime(31757): at io.flutter.plugins.googlemobileads.GoogleMobileAdsPlugin.onMethodCall(GoogleMobileAdsPlugin.java:330) [ ] E/AndroidRuntime(31757): at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.onMessage(MethodChannel.java:233) [ ] E/AndroidRuntime(31757): at io.flutter.embedding.engine.dart.DartMessenger.handleMessageFromDart(DartMessenger.java:85) [ ] E/AndroidRuntime(31757): at io.flutter.embedding.engine.FlutterJNI.handlePlatformMessage(FlutterJNI.java:818) [ ] E/AndroidRuntime(31757): at android.os.MessageQueue.nativePollOnce(Native Method) [ ] E/AndroidRuntime(31757): at android.os.MessageQueue.next(MessageQueue.java:336) [ ] E/AndroidRuntime(31757): at android.os.Looper.loop(Looper.java:197) [ ] E/AndroidRuntime(31757): at android.app.ActivityThread.main(ActivityThread.java:8167) [ ] E/AndroidRuntime(31757): at java.lang.reflect.Method.invoke(Native Method) [ ] E/AndroidRuntime(31757): at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:496) [ ] E/AndroidRuntime(31757): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1100) [ +33 ms] I/Process (31757): Sending signal.
