خطای گریدل

[DexterFstone 387]

سلام

من طبق مستندات مایکت پیش رفتم و خط زیر به گریدل اضافه کردم

android {
    defaultConfig {
        def marketApplicationId = "ir.mservices.market"
        def marketBindAddress = "ir.mservices.market.InAppBillingService.BIND"
        manifestPlaceholders = [marketApplicationId: "${marketApplicationId}",
                marketBindAddress  : "${marketBindAddress}",
                marketPermission   : "${marketApplicationId}.BILLING"]
        buildConfigField "String", "IAB_PUBLIC_KEY", "\"{MYKET_PUBLIC_KEY}\""
    }
}

اما خطای زیرا دریافت میکنم

AndroidManifest.xml Error:
Attribute action#${marketApplicationId}.ping@name at AndroidManifest.xml requires a placeholder substitution but no value for <marketApplicationId> is provided.
  AndroidManifest.xml Error:
Attribute user-permission#${marketPermission}.ping@name at AndroidManifest.xml requires a placeholder substitution but no value for <marketPermission> is provided.
  AndroidManifest.xml Error:
Attribute action#${marketBindAddress}.ping@name at AndroidManifest.xml requires a placeholder substitution but no value for <marketBindAddress> is provided.
