哪里有cognito秘密哈希密钥

Question

我试图创建一个简单的android / aws项目，但我收到错误而且我不知道在哪里看。请注意确定是否重要但我尝试将我的应用程序连接到身份池以让用户使用电子邮件地址登录。

public class MainActivity extends AppCompatActivity {

    //AWS Housekeeping
    public static PinpointManager pinpointManager;
    private DynamoDBMapper dynamoDBMapper;
    private final String POOL_ID = "xxxxxxxx";
    private final String USER_POOL = "xxxxxxxxx";

    private AWSCredentialsProvider awsCredentialsProvider;
    private AWSConfiguration awsConfiguration;

    private Button loginBtm;
    private Button createUserBtm;
    private EditText emailField;
    private EditText passwordField;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        createUserBtm = findViewById(R.id.createButton);
        loginBtm = findViewById(R.id.loginButton);
        emailField = findViewById(R.id.usernameField);
        passwordField = findViewById(R.id.passwordField);

        final Intent newUserIntent = new Intent(this, NewUserActivity.class);
        final Intent signInIntent = new Intent(this, HomeActivity.class);


        AWSMobileClient.getInstance().initialize(this, new AWSStartupHandler() {
            @Override
            public void onComplete(AWSStartupResult awsStartupResult) {

                // Obtain the reference to the AWSCredentialsProvider and AWSConfiguration objects
                awsCredentialsProvider = AWSMobileClient.getInstance().getCredentialsProvider();
                awsConfiguration = AWSMobileClient.getInstance().getConfiguration();


                // Use IdentityManager #getUserID to fetch the identity id.
                IdentityManager.getDefaultIdentityManager().getUserID(new IdentityHandler() {
                    @Override

                        Log.d("YourMainActivity", "Identity ID = " + identityId);

                        // Use IdentityManager#getCachedUserID to
                        //  fetch the locally cached identity id.
                        final String cachedIdentityId =
                                IdentityManager.getDefaultIdentityManager().getCachedUserID();
                    }

                    }
                });
            }
        }).execute();





        createUserBtm.setOnClickListener(new View.OnClickListener() {
            @Override

                }
            }
        });
