title: I am using multiple firebase projects in an Android App. I am getting this error : Missing google_app_id. Firebase Analytics disabled
body: <p>I have added following code to initialise there projects. </p>
  
  <pre><code>FirebaseOptions options = new FirebaseOptions.Builder()
              .setApplicationId("1:129574837465:android:0123456773a52cf4f6") // Required for Analytics.
              .setApiKey("iubdeibneh8gzDt7Xn9f-jdjjdjdjdj") // Required for Auth.
              .setDatabaseUrl("https://databasename-d7r7.firebaseio.com") // Required for RTDB.
              .build();
  
  FirebaseApp.initializeApp(context /* Context */, options, "secondary");
  
  
  FirebaseOptions options2 = new FirebaseOptions.Builder()
              .setApplicationId("1:129574837465:android:0123456773a52cf4f6") // Required for Analytics.
              .setApiKey("iubdeibneh8gzDt7Xn9f-jdjjdjdjdj") // Required for Auth.
              .setDatabaseUrl("https://databasename2-d7r7.firebaseio.com") // Required for RTDB.
              .build();
  
  FirebaseApp.initializeApp(context /* Context */, options2, "secondary2");
  
  
  FirebaseOptions options3 = new FirebaseOptions.Builder()
              .setApplicationId("1:129574837465:android:0123456773a52cf4f6") // Required for Analytics.
              .setApiKey("kjdkj-o_3nk4jn4k3kjk23j") // Required for Auth.
              .setDatabaseUrl("https://databasename3-d7r7.firebaseio.com") // Required for RTDB.
              .build();
  
  FirebaseApp.initializeApp(context /* Context */, options3, "secondary3");
  </code></pre>
  
  <p>After initialisation my app is running fine. I can use FirebaseAuth, and FirebaseRTDB just fine but it is throwing error when it has to access firebase_Application_Id for analytics. </p>
  
  <p>I have cross checked the ids from google-services.json files of all the projects. I don't know why but it throws error saying:</p>
  
  <pre><code>Missing google_app_id. Firebase Analytics disabled.
  </code></pre>
  
  <p>I couldn't figure out the root of this error.</p>
