集成了亚马逊网络服务分析的安卓应用无法读取awsconfiguration.json

Question

我正在学习教程here

我只是想尝试一下Android开发和AWS集成。我按照this guide设置了一个基本的helloworld安卓应用。然后继续在第一个链接中添加AWS组件。

当我到达"Monitor Analytics“部分时，我的项目将构建，但在运行时抛出异常。

例外情况如下：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.xx.xxxx.wearables_data_receiver.app/com.xx.xxxx.wearables_data_receiver.feature.MainActivity}: java.lang.RuntimeException: Failed to read awsconfiguration.json please check that it is correctly formed.

    at com.amazonaws.mobile.config.AWSConfiguration.readInputJson(AWSConfiguration.java:88)

这行代码：

at com.xx.xxxx.wearables_data_receiver.feature.MainActivity.onCreate(MainActivity.java:51)

指向第一个链接中教程中的"AWSMobileClient.getInstance().initialize“调用：

AWSMobileClient.getInstance().initialize(this, new AWSStartupHandler() {
        @Override
        public void onComplete(AWSStartupResult awsStartupResult) {
            System.out.println("AWSMobileClient is instantiated and you are connected to AWS!");
        }
    }).execute();

我不知道这是怎么回事，我试着打开文件权限，并把它放在几个不同的目录中，但都没有用。任何帮助都将不胜感激。

该错误是由于缺少awsconfiguration.json文件造成的。

 Caused by: java.lang.RuntimeException: Failed to read awsconfiguration.json please check that it is correctly formed.

您能确保将awsconfiguration.json文件放在res/raw目录中并具有有效的json吗？如果您使用Amplify CLI进行设置，则应始终使用所需信息自动更新awsconfiguration.json文件。
