您是否按照 ionic 应用程序的 android 安装说明进行操作？通常您不需要 NDK。

这是你的固定文件。

        classpath 'com.google.gms:google-services:4.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
