Question

我正在学习教程here

我只是想尝试一下Android开发和AWS集成。我在this guide之后设置了基本的helloworld Android应用。然后继续在第一个链接中添加AWS组件。

当我进入“ Monitor Analytics”部分时，我的项目将构建，但在运行时会引发异常。

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 android.content.res.Resources.openRawResource(Resources.java:1241)
    at com.amazonaws.mobile.config.AWSConfiguration.readInputJson(AWSConfiguration.java:88)

该行：

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

在第一个链接中指向教程中的“ 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();

我不确定这里发生了什么，我尝试打开文件权限，并将其放置在几个不同的目录中，但无济于事。任何帮助将不胜感激。

该错误是由于缺少awsconfiguration.json文件。

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

您可以确保将awsconfiguration.json文件放置在res/raw目录中并且具有有效的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。

带有AWS Analytic Integration的Android应用无法读取awsconfiguration.json
