FirebaseRemoteConfig.getInstance上的空指针

我通过MainActivity.onCreate获取FirebaseRemoteConfig实例。这是简单的setupCode，但某些设备上的生产正在发生崩溃。这是堆栈跟踪。我正在使用playservices 9.0.1。FirebaseRemoteConfig.getInstance上的空指针

有什么想法？

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; 
      } 
     }

的是在这行代码com.buscaalimento.android.view.viewcontroller.MainActivity。 setupFirebaseRemoteConfig（MainActivity.java:476）？ – Shubhank

我编辑并添加了代码@Shubhank。谢谢 –

你还需要告诉那行代码，因为我不知道代码中的行号码 – Shubhank
