Initialize FirebaseApp without google-services.json

* Android Studio version: _3.2_
* Firebase Component: Core/Analytics(Database, Firestore, Storage, Functions, etc)
* Component version: 16.0.4

### [REQUIRED] Step 3: Describe the problem

I am trying to initialize the FirebaseApp, only by using the FirebaseOptions builder, like this, first thing in my application (I use only applicationId and ApiKey, since I only want the analytics for start) :

```java
FirebaseOptions options = new FirebaseOptions.Builder()
.setApplicationId(applicationID) // Required for Analytics.
.setApiKey(apiKey) // Required for Auth.
.build();
FirebaseApp.initializeApp(context, options);
```

I do not have a google-services.json file in my project, I have removed the FirebaseInitProvider, like this, in my AndroidManifest.xml:

```xml
.
```

When starting the application, while trying to View events in the Android Studio debug log, like this:
adb shell setprop log.tag.FA VERBOSE
adb shell setprop log.tag.FA-SVC VERBOSE
adb logcat -v time -s FA FA-SVC

I get Missing google_app_id. Firebase Analytics disabled. See https://goo.gl/NAOOOI .
