How to use FirebaseApp.initializeApp for FirebaseRemoteConfig

I am trying to use FirebaseApp.initializeApp, but its not working. I have the right library, but I cannot use the JSON file to initialize the app

This is my code:

Imports

import com.google.firebase.FirebaseApp;
import com.google.firebase.FirebaseOptions;
import com.google.firebase.remoteconfig.FirebaseRemoteConfig;
import com.google.firebase.remoteconfig.FirebaseRemoteConfigSettings;

Variables

private FirebaseRemoteConfig mFirebaseRemoteConfig;

private String projectID;
private String apiKey;
private String appID;

How I initialize the app

public void Initialize() {
    FirebaseOptions mFirebaseOptions = new FirebaseOptions.Builder()
        .setApplicationId(this.appID)
        .setApiKey(this.apiKey)
        .build();
    FirebaseApp.initializeApp(this.context, mFirebaseOptions, this.projectID);
    mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
}

The app crashed on startup this is the logcat error:

Hey I am suggesting some solutions -

  1. Build.gradle file

    multiDexEnabled true

  2. Add this in your proguard-rules.pro file

    -keep public class com.google.android.gms.* { public *; }

There may be multiple problems. I'll point out what appears to be one.

The documentation for RemoteConfig.getInstance() notes that it expects the default FirebaseApp to be initialized:

FirebaseRemoteConfig uses the default FirebaseApp...

Unlike some of the other Firebase APIs, there is no way to initialize RemoteConfig using a different FirebaseApp.

That means that when you initialze FirebaseApp, projectID must be "[DEFAULT]", which is available as constant FirebaseApp.DEFAULT_APP_NAME.

FirebaseApp.initializeApp(this.context, mFirebaseOptions, this.projectID);

Try setting projectID to "[DEFAULT]" (or the available constant) to see if the failure changes or is resolved.

Disable the instant-run while generating application and make sure you have added google-services.json file to your project.
