使用事实验证错误我的android应用程序

您好，我正在android studio中开发一个应用程序，使用事实api查找餐厅。主要活动的代码如下（我有钥匙，我现在用xxx替换）

这是清单文件

<?xml version="1.0" encoding="utf-8"?>

当我在我的物理android设备上调试应用程序时，应用程序崩溃，我出现以下错误：

错误行如下所示：

ReadResponse italian = factual.fetch("restaurants-us", query);

在创建

Factual

类的实例时，是否传递了正确的api密钥和api机密？请使用更易于集成的Google Places api。
