Android Studio中的編譯器開關

Question

有沒有辦法給編譯器提供一段源代碼不能編譯或編譯的命令？例如：

 // To set the adView with some listener 
    final AdView adView = (AdView) this.findViewById(R.id.adView); 
    adView.setAdListener(new AdListener() { 
     @Override 
     public void onAdFailedToLoad(int errorCode) { 
      super.onAdFailedToLoad(errorCode); 
      adView.setVisibility(View.GONE); 
     } 

     @Override 
     public void onAdLoaded() { 
      super.onAdLoaded(); 
      adView.clearFocus(); 
      adView.setVisibility(View.VISIBLE); 
     } 
    }); 

    //request TEST ads to avoid being disabled for clicking your own ads 
    AdRequest adRequest = new AdRequest.Builder() 
      .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)// This is for emulators 
      //test mode on DEVICE (this example code must be replaced with your device uniquq ID) 
      .build(); 
    adView.loadAd(adRequest); 

這段代碼我想要版本X和版本Y這個源代碼忽略，如果我構建的APK。我想在一個源代碼中有兩個或更多版本，我將控制構建APK中的哪些源代碼。

您可以配置構建變體DEBUG/RELEASE以根據它執行代碼路徑。另一種選擇是定義多種產品風味，其產品風味變量對於每種風味都不相同。
