我对AWS非常陌生。我终于得到它的工作。我用它作为我的主要代码：
package elthran.testingaws;
import android.app.Activity;
import android.os.Bundle;
import com.amazonaws.auth.CognitoCachingCredentialsProvider;
import com.amazonaws.mobile.auth.ui.SignInUI;
import com.amazonaws.mobile.client.AWSMobileClient;
import com.amazonaws.mobile.client.AWSStartupHandler;
import com.amazonaws.mobile.client.AWSStartupResult;
import com.amazonaws.regions.Regions;
public class AuthenticatorActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_authenticator);
// Add a call to initialize AWSMobileClient
AWSMobileClient.getInstance().initialize(this, new AWSStartupHandler() {
@Override
public void onComplete(AWSStartupResult awsStartupResult) {
SignInUI signin = (SignInUI) AWSMobileClient.getInstance().getClient(
AuthenticatorActivity.this,
SignInUI.class);
signin.login(
AuthenticatorActivity.this,
MainActivity.class).execute();
}
}).execute();
}
}
它打开了一个基本的登录窗口，让我创建一个帐户。它已在AWS联合身份中注册。然后，我尝试使用新帐户登录到该应用程序，但不断出现此错误。谁能帮忙解释原因？

除了麻烦我什么都没有。我希望登录重定向到我的MainActivity，这是一个简单的“ hello world”文本页面，只是为了确保我有一个正常的创建用户和登录页面。似乎有很多可能的问题，对于初学者来说，阅读这些错误日志非常困难。任何帮助将不胜感激。
