Build failed on AndroidStudio

Hi,
While trying to run build in my AS with the following config:
`apply plugin: 'com.android.application'

android {
compileSdkVersion 'Google Inc.:Google APIs:15'
buildToolsVersion "30.0.2"

defaultConfig {
    applicationId "org.onaips.vnc"
    minSdkVersion 23
    targetSdkVersion 30
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_5
        targetCompatibility JavaVersion.VERSION_1_5
    }
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}
externalNativeBuild {
    ndkBuild {
        path file('../../../droidVncServer-master/jni/Android.mk')
    }
}

}

dependencies {
compile files('libs/GoogleAdMobAdsSdk-6.0.1.jar')
}
Using NDK version 21.3.6528147 got the following errors: :11:9: error: unknown directive
:2:9: error: unknown directive
