MainActivity.onCreate を通じて FirebaseRemoteConfig インスタンスを取得しています。シンプルな setupCode ですが、一部のデバイスの本番環境でクラッシュが発生しています。これがスタックトレースです。プレイサービス 9.0.1 を使用しています。

何かご意見は？

  protected void onCreate(Bundle savedInstanceState) {

          super.onCreate(savedInstanceState);
          setupFirebaseRemoteConfig(); //line 476
  }


  private void setupFirebaseRemoteConfig() {

          mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();

          FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings.Builder()
                  .setDeveloperModeEnabled(BuildConfig.DEBUG)
                  .build();

          mFirebaseRemoteConfig.setConfigSettings(configSettings);
          mFirebaseRemoteConfig.setDefaults(R.xml.remote_config);

          configCacheExpiration = 3600;

          if (mFirebaseRemoteConfig.getInfo().getConfigSettings().isDeveloperModeEnabled()) {
              configCacheExpiration = 0;
          }
      }
