title: Expo-google-app-auth gives error while signing in
body: <p>I'm making an app in react native and really need to add google auth. But I can't get it to work. It shows an error: <code>ExpoAppAuth.Get Auth: Encountered exception when trying to start auth request: null</code></p>
  <h2>Code</h2>
  <h4>My Sign-In function</h4>
  <pre><code>signInAsync = async () =&gt; {
          try {
            const conf = {
              androidClientId: config.google_client_id,
            }
            let result = await Google.logInAsync(conf);
            if (result.type === 'success') {
              console.log(result.accessToken);
              this.props.navigation.navigate('dashboard');
            } else {
              return { cancelled: true };
            }
