firebase - 我正在尝试在我的颤振项目中使用“google_mobile_ads”，但我正在将其迁移到 Android 嵌入 v2

Question

该插件google_mobile_ads要求您的应用迁移到 Android 嵌入 v2。按照https://flutter.dev/go/android-project-migration上的步骤重新运行此命令。

所以我尝试按照这些步骤操作，但在我的项目中任何地方都找不到“MainActivity.java”，也无法继续

我的项目树

迁移错误

https://flutter.dev/go/android-project-migration 这是它建议遵循的链接

Answer 1

只需在您的项目中打开这些文件并复制>>粘贴这行代码，它就会起作用.......确保删除此文件中的所有代码行并将其替换为新的代码行。

1：MainActivity.java

---

package co.appbrewery.flash_chat;

import io.flutter.embedding.android.FlutterActivity;

public class MainActivity extends FlutterActivity {
  
}

---

2：样式.xml

---

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
    <item name="android:windowBackground">@drawable/launch_background</item>
</style>
</resources>

3：AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"   
          package="co.appbrewery.flash_chat">

     calls FlutterMain.startInitialization(this); in its onCreate method.

     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->
