当我尝试在我的 Flutter 应用中使用 Facebook 广告时，我已经遇到了这个问题。

试试这个：

android/build.gradle

添加这一行

classpath 'com.android.tools.build:gradle:3.6.4'

您的代码应如下所示

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.4'  // Add Here
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

在此之后转到 android\gradle\wrapper\gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip

只需替换您的 distributionUrl 即可。你的问题会解决。如果您仍然面临这个问题，那么让我来

我已经升级了我的 gradle，运行 Flutter Doctor 没有发现任何问题。 但我仍然收到错误消息。

插件facebook_audience_network, flutter_statusbarcolor_ns, flutter_webview_plugin, notification_permissions, onesignal_flutter, sms_autofill 使用已弃用的 Android 嵌入版本。

Answer 3

升级您的 Gradle 插件。您可以在项目级别的build.gradle 文件中升级版本：

buildscript {

    repositories {
        google()
        jcenter()
    }

    dependencies {
        // classpath 'com.android.tools.build:gradle:4.0.0'
        classpath 'com.android.tools.build:gradle:4.0.1'
    }
}
