We can call Cloud Functions for Firebase from Android using Cloud Functions for Firebase client SDK.
If you are using Google Cloud Functions, you can make Google Cloud Functions compatible with Cloud Functions for Firebase.
You also make HTTP request to Cloud Functions for Firebase without using Cloud Functions for Firebase client SDK.
NOTE: Cloud Functions for Firebase client SDK provide some convinience and intergration with other Firebase services like Firebase Authentication.
Include dependencies.
dependencies {
implementation 'com.google.firebase:firebase-functions:16.3.0'
}Code
NOTE: Assume test_firebase_function expect a name parameter and return a name response as well.
fun getFirebaseFunction(): Task<String> { val functions = FirebaseFunctions.getInstance() val data = mapOf( "name" to "Desmond" ) return functions.getHttpsCallable("test_firebase_function") .call(data) .continueWith { task -> val result = task.result?.data as HashMap<*, *> result["name"] as String }}getFirebaseFunction().addOnCompleteListener { task -> if (task.isSuccessful) { val name = task.result Timber.d("name=$name") } else { Timber.e(task.exception) }}NOTE: There might be some firebase prerequisites.
NOTE: Refer Kotlin Convert Hashmap to Object (Kotlin Serialization).
