FirebaseRemoteConfig.getInstance上的空指針

我通過MainActivity.onCreate獲取FirebaseRemoteConfig實例。這是簡單的setupCode，但某些設備上的生產正在發生崩潰。這是堆棧跟蹤。我正在使用playservices 9.0.1。FirebaseRemoteConfig.getInstance上的空指針

有什麼想法？

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; 
      } 
     }

的是在這行代碼com.buscaalimento.android.view.viewcontroller.MainActivity。 setupFirebaseRemoteConfig（MainActivity.java:476）？ – Shubhank

我編輯並添加了代碼@Shubhank。謝謝 –

你還需要告訴那行代碼，因爲我不知道代碼中的行號碼 – Shubhank
