One of the Best way to use build.gradle file in latest Android 5.0 and Android 6.0, Android 9+ (API 20, 21,22,23, 24, 25,26, 27 28, 29)

Well you can use them simply without creating product flavors in gradle. This is another example we can achieve via Gradle. You can achieve it with two simple steps.

• Add custom value to manifestplaceholders build.gradle file.

See below

buildTypes {
    debug {
        manifestPlaceholders = [ mapApiKeyValue:"GHjaSyAjlyp3O831lgaonHMXsd-_DpQ3002x3S4"]
    }

    release {
        manifestPlaceholders = [ mapApiKeyValue:"AIzaSyAuMGDLr2HeuRed4JA0CrdYYdZRjeC3EA"]
    }
}

• Edit manifest file like below.

part of my manifest file

This solution works for the latest Android 5.0 and Android 6.0 (API 20, 21,22,23)

#if DEBUG
   [assembly: MetaData("com.google.android.maps.v2.API_KEY", Value = "DebugKey123123123")]
#else
