Question

Auth.Builder builder = new Auth.Builder().setAppClientId(getString(R.string.cognito_client_id))
            .setAppClientSecret(getString(R.string.cognito_client_secret))
            .setAppCognitoWebDomain(getString(R.string.cognito_web_domain))
            .setApplicationContext(getApplicationContext())
            .setAuthHandler(new callback())
            .setSignInRedirect(getString(R.string.app_redirect))
            .setSignOutRedirect(getString(R.string.app_redirect));
    this.auth = builder.build();
    appRedirect = Uri.parse(getString(R.string.app_redirect));
}

 <!-- TODO: Add your Cognito pool details here -->
<string name="cognito_web_domain">domain</string>
<string name="cognito_client_id">client id</string>
<string name="cognito_client_secret">client secret</string>
<string name="app_redirect">redicrec</string>

例外情况：

Answer 1

首先，您需要打开Cognito控制台。然后选择here选项User Pools并继续。如果您没有任何用户池，则必须创建它。第二，查看左侧菜单，进入“APP客户端”。也为你的应用程序添加一个或使用现有的。如果一切正常，你会看到下面的图片。

接下来，在左侧控制台菜单检查您的域名，并在需要时创建它。如果完成了，返回到项目并找到文件Strings.xml。更改此节：

<!-- Here below need your Domain Name -->
<string name="cognito_web_domain">yourDomainName.amazoncognito.com</string>
<!-- Write below your App Client ID -->
<string name="cognito_client_id">_id</string>
<!-- Write below your App Client Secret -->
<string name="cognito_client_secret">_secret</string>
<!-- This not influences on validate, may leave as is -->
<string name="app_redirect">demoapp://www.loginactivity.com/mainactivity</string>
