Firebase 仪表板不显示顶级产品的价格
Firebase dashboard doesn't show price in top products
在 Firebase 仪表板中，查看 add_to_cart 事件时，我可以看到价格参数成功触发：
但是下面 "top products" window，我看不到任何价格：
我正在尝试了解原因。是不是因为我没有发送值参数（我只发送价格和货币）
谢谢
您第一个屏幕截图中的事件摘要显示已发送 price 参数。这可以是一个字符串，一个数字，任何东西。在你的情况下，它是一个数字。
第二个屏幕截图中的产品摘要显示已发送 value 参数。这必须是货币价值，并且是您应该使用的货币价值。
来自the docs：
public static final String VALUE
A context-specific numeric value which is accumulated automatically
for each event type. Value should be specified with putLong(String, long) or putDouble(String, double). This is a general purpose
parameter that is useful for accumulating a key metric that pertains
to an event. Examples include revenue, distance, time, and points.
Notes: Values for pre-defined currency-related events (such as
ADD_TO_CART) should be accompanied by a CURRENCY param. The valid
range of accumulated values is [-9,223,372,036,854.77, 9,223,372,036,854.77]. Supplying a non-numeric value, omitting the
corresponding CURRENCY parameter, or supplying an invalid currency
code for conversion events will cause that conversion to be omitted
from reporting.
Bundle params = new Bundle();
params.putDouble(Param.VALUE, 3.99);
params.putString(Param.CURRENCY, "USD" ); // e.g. .99 USD
