Android Firebase Analytics: predefined and custom parameters not working

问题

I have application which use Firebase SDK and used some predefined event and parameters but some parameters are automatically added but not all parameters

For example Add to cart event

Android :

bundle.putString(FirebaseAnalytics.Param.ITEM_CATEGORY, params.get("item_category").toString());
bundle.putString(FirebaseAnalytics.Param.ITEM_NAME, params.get("item_name").toString());
bundle.putString(FirebaseAnalytics.Param.ITEM_LOCATION_ID, params.get("item_location_id").toString());
bundle.putString(FirebaseAnalytics.Param.CURRENCY, params.get("currency").toString());
bundle.putDouble(FirebaseAnalytics.Param.VALUE, ((Number) params.get("value")).doubleValue());
bundle.putString(FirebaseAnalytics.Param.COUPON, params.get("coupon").toString());
bundle.putString(FirebaseAnalytics.Param.ITEM_ID, params.get("item_id").toString());
bundle.putLong(FirebaseAnalytics.Param.QUANTITY, ((Number) params.get("quantity")).longValue());
this.firebaseAnalytics.logEvent(FirebaseAnalytics.Event.ADD_TO_CART, bundle);

IOS

[FIRAnalytics logEventWithName:kFIREventAddToCart parameters:@{
    kFIRParameterItemCategory:[parameters valueForKey:@"item_category"],
    kFIRParameterItemName:[parameters valueForKey:@"item_name"],
    kFIRParameterItemLocationID:[parameters valueForKey:@"item_location_id"],
    kFIRParameterCurrency:[parameters valueForKey:@"currency"],
    kFIRParameterValue:[parameters valueForKey:@"value"],
    kFIRParameterCoupon:[parameters valueForKey:@"coupon"],
    kFIRParameterItemID:[parameters valueForKey:@"item_id"],
    kFIRParameterQuantity:[parameters valueForKey:@"quantity"]
}];

In dashboard, We can see only item_name and value. please help.... thanks in advance

I'm supposing that your params object is a composed array with the similar values

{
    "item_category" : "t-shirts",
    "item_name" : "abc",
    "item_location_id" : "ChIJiyj437sx3YAR9kUWC8QkLzQ",
    "currency" : "USD",
    "value" : 3.99,
    "coupon" : "zz123",
    "item_id" : "p7654",
    "quantity" : 1
}

If that is the case then you are in the right way to create the event. But you are trying to see the event values in the Parameter Reporting section in the Firebase Console. I analysed based on the image you attached.

If you want to see the event values I recommend check the event dashboard report by clicking on the event name instead of the tab Parameter Reporting, follow this link, it shows you an example of how Firebase Events are organized in the Dashboard Console.

I hope this helps you.
