I have used API_KEY="my_api_key" in gradle.properties file and added buildConfigField("String", "API_KEY", API_KEY) to app/gradle file and define private static final String API_KEY = BuildConfig.API_KEY; to activity class and initiliized on create method Places.initialize(this, API_KEY);
I have tried to concate string also but same issue. I restricted my API also in google console by adding SHA keys for both debug and release but still the same issue
