android {
defaultConfig {
applicationId "com.example.myapp"
}
productFlavors {
free {
applicationIdSuffix ".free"
}
pro {
applicationIdSuffix ".pro"
}
}
}
android {
...
flavorDimensions "default"
...
}
It is better to use different
AndroidManifest.xmlandgoogle-services.jsonfile for each flavor

Generate Java Constants
android {
buildTypes {
debug {
buildConfigField "int", "FOO", "42"
buildConfigField "String", "FOO_STRING", "\"foo\""
buildConfigField "boolean", "LOG", "true"
}
release {
buildConfigField "int", "FOO", "52"
buildConfigField "String", "FOO_STRING", "\"bar\""
buildConfigField "boolean", "LOG", "false"
}
}
}
You can access them with BuildConfig.FOO
Generate Android resources
android {
buildTypes {
debug{
resValue "string", "app_name", "My App Name Debug"
}
release {
resValue "string", "app_name", "My App Name"
}
}
}
You can access them in the usual way with @string/app_name or R.string.app_name
String type build config fields should be declared like this:
buildConfigField "String", "SERVER_URL", "\"http://dev.myserver.com\""
