title: Unable to initialise App Check for Android app
body: <p>I am trying to run a callable cloud function on the emulator but I'm failing because the app check is not successful</p>
  <p>Here's the launcher activity of my app. The activity calling the function is different.</p>
  <pre><code>super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_splash_screen);
  
          Objects.requireNonNull(getSupportActionBar()).hide();
  
          FirebaseApp.initializeApp(this);
          FirebaseAppCheck firebaseAppCheck = FirebaseAppCheck.getInstance();
          firebaseAppCheck.installAppCheckProviderFactory(SafetyNetAppCheckProviderFactory.getInstance());
  </code></pre>
  <hr />
  <p>The error I'm getting is:</p>
  <pre><code>W/FirebaseContextProvider: Error getting App Check token; using placeholder token instead.
  Error: com.google.firebase.FirebaseException: Error returned from API. code: 403 body: App attestation failed: 1:&lt;number&gt;:android&lt;number&gt;:
  </code></pre>
  <p>I don't get how I should be initialising App Check instead.</p>
