AWSサインインの問題-サインイン中にトークンをフェデレーションできませんでしたjava.lang.RuntimeException：トークンのフェデレーション中にエラーが発生しました。-Android
Amplifierconfiguration.jsonでユーザープールIDを変更した後、既存のユーザープールでは正常にサインアップできますが、サインイン中にこのエラーが発生します。
サインインの場合、Amplify.Auth.signIn（ "*** "、 " "、result-> {Log.i（ "AuthQuickstart"、result.isSignInComplete（）？ "サインインに成功しました：" + result.toString（ ）： "サインインが完了していません"）; if（result.isSignInComplete（））{Toast.makeText（SplashActivity.this、 "SignIn"、Toast.LENGTH_LONG）.show（）;}}、エラー-> Log.e（ "AuthQuickstart"、error.toString（）））; このmettod。

アクセストークンを取得するためだけに増幅するためにサインインしている場合は、特定のユーザープールのトークンを取得するもう1つの方法があります。ユーザー名とパスワードを使用してユーザープールを認証してから、次のようにトークンを要求できます。
public class AWSService {
public IdentityManager identityManager ;
public AWSCredentialsProvider credentialsProvider ;
public AWSConfiguration awsConfiguration;
public AWSService(Context context) {
awsConfiguration = new AWSConfiguration(context);
identityManager = new IdentityManager(context, awsConfiguration);
identityManager.addSignInProvider(CognitoUserPoolsSignInProvider.class);
IdentityManager.setDefaultIdentityManager(identityManager);
credentialsProvider = identityManager.getCredentialsProvider();
}}
public static void getAccessToken(Context context, int requestCode, GetUserPoolTokenListener getUserPoolTokenListener) {
AWSService awsService=new AWSService(context);
CognitoUserPool cognitoUserPool=new CognitoUserPool(context,
awsService.awsConfiguration);
AuthenticationDetails authDetails = new AuthenticationDetails(PreferenceUtils.getStringPref(context,Constants.USER_NAME), PreferenceUtils.getStringPref(context,Constants.PASSWORD), null);
final CognitoUser cognitoUser = cognitoUserPool.getUser();
cognitoUser.initiateUserAuthentication(authDetails, new AuthenticationHandler() {
@Override
public void onSuccess(CognitoUserSession userSession, CognitoDevice newDevice) {
Log.e("aws","onSuccess : "+userSession.getIdToken().getExpiration().getTime());
}
@Override
public void getAuthenticationDetails(AuthenticationContinuation authenticationContinuation, String userId) {
Log.e("aws","getAuthenticationDetails : "+authenticationContinuation);
}
@Override
public void getMFACode(MultiFactorAuthenticationContinuation continuation) {
Log.e("aws","getMFACode : "+continuation);
}
@Override
public void authenticationChallenge(ChallengeContinuation continuation) {
Log.e("aws","authenticationChallenge : "+continuation);
}
@Override
public void onFailure(Exception exception) {
Log.e("aws","onFailure : "+exception);
}
}, true).run();
}
