cannot find symbol import com.user.userCom

Trying to create native module for react-native. I have all the dependencies needed and I followed the instructions user com mobile sdk installation
in project/android/build.gradle
allprojects {
repositories {
…
maven {
url 'https://android-sdk.user.com'
}
}
}
in project/android/app/build.gradle
dependencies {
implementation 'com.user:android-sdk:1.0.0'
}
then i created file in project/app/src/main/java/com/my_app/UserComModule.java
package com.my_app;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.bridge.ReactContextBaseJavaModule;
import com.facebook.react.bridge.ReactMethod;
import java.util.Map;
import java.util.HashMap;
import com.user.UserCom;
public class UserComModule extends ReactContextBaseJavaModule {
private static ReactApplicationContext reactContext;
#Override
public void onCreate() {
super.onCreate();
new UserCom.Builder(
this,
"api_secret", //your api secret key generated in User.com webpanel details
"https://<your_app_subdomain>.user.com"
)
.trackAllActivities(true) // false by default
.openLinksInChromeCustomTabs(true) // true by default
.setCustomTabsBuilder(getCustomTabsBuilder())
.build();
}
}
When i run i get: cannot find symbol import com.user.UserCom;

You're importing UserCom, and that module is not availabe, as you've mentioned you had created the file UserComModule in that directory, either create UserCom class or delete this line from UserComModule
import com.user.UserCom;

how to pass url in httptarget method while using PACT

while creating pact verification test i am using httpTarget Method. but the problem is my service dont have a port value. how can we run this? please advise.
Service URL=http://services.groupkt.com/country/get/iso3code/IND
below is my verification test.
package se.ff.bsv;
import au.com.dius.pact.provider.junit.PactRunner;
import au.com.dius.pact.provider.junit.Provider;
import au.com.dius.pact.provider.junit.State;
import au.com.dius.pact.provider.junit.loader.PactFolder;
import au.com.dius.pact.provider.junit.loader.PactUrl;
import au.com.dius.pact.provider.junit.target.HttpTarget;
import au.com.dius.pact.provider.junit.target.Target;
import au.com.dius.pact.provider.junit.target.TestTarget;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.ClassRule;
import org.junit.runner.RunWith;
import java.net.URL;
import java.util.Map;
#RunWith(PactRunner.class) // Say JUnit to run tests with custom Runner
#Provider("getCountryService") // Set up name of tested provider
#PactFolder("../pacts") // Point where to find pacts (See also section Pacts source in documentation)
//#PactUrl(urls = {"http://services.groupkt.com/country/get/iso3code/IND"} )
public class getCountryContractTest {
#State("There is a country with alpha2_code as IN having name as India") // Method will be run before testing
// interactions that require "with-data"
// state
public void hammerSmith() {
System.out.println("There is a country with alpha2_code as IN having name as India");
}
#TestTarget // Annotation denotes Target that will be used for tests
//public final Target target = new HttpTarget(8111);// Out-of-the-box implementation of Target (for more information take a look at Test Target section)
public final Target target = new HttpTarget("http", "services.groupkt.com",);
}

You can't say your service don't have a port, but you can say your service uses a default port (for instance). In that case, try to use port 80.

EMR Cluster creation using Java

I am trying to create an EMR Cluster using Java. I have created the jar file and put that into a lambda function. I'm calling the lambda from AWS Step functions. I created the maven package including the AWS JAVA SDK dependencies and also imported all the packages
import java.io.IOException;
import com.amazonaws.auth.*;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.auth.PropertiesCredentials;
import com.amazonaws.services.elasticmapreduce.*;
import com.amazonaws.services.elasticmapreduce.model.AddJobFlowStepsRequest;
import com.amazonaws.services.elasticmapreduce.model.AddJobFlowStepsResult;
import com.amazonaws.services.elasticmapreduce.model.RunJobFlowRequest;
import com.amazonaws.services.elasticmapreduce.model.*;
import com.amazonaws.services.elasticmapreduce.model.HadoopJarStepConfig;
import com.amazonaws.services.elasticmapreduce.model.StepConfig;
import com.amazonaws.services.elasticmapreduce.util.StepFactory;
import com.amazonaws.AmazonServiceException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
public class CreateCluster {
public static void main(String[] args) {
AWSCredentials credentials = new BasicAWSCredentials("access key", "secret key");
// myApp={[Hadoop]};
AmazonElasticMapReduceClient emr = new AmazonElasticMapReduceClient(credentials);
String COMMAND_RUNNER = "command-runner.jar";
String DEBUGGING_COMMAND = "state-pusher-script";
String DEBUGGING_NAME = "Setup Hadoop Debugging";
StepFactory stepFactory = new StepFactory();
StepConfig enabledebugging = new StepConfig()
.withName(DEBUGGING_NAME)
.withActionOnFailure(ActionOnFailure.TERMINATE_CLUSTER)
.withHadoopJarStep(new HadoopJarStepConfig()
.withJar(COMMAND_RUNNER)
.withArgs(DEBUGGING_COMMAND));
RunJobFlowRequest request = new RunJobFlowRequest()
.withName("REMR")
.withReleaseLabel("emr-5.16.0")
.withSteps(enabledebugging)
// .withApplications(myApp)
.withLogUri("s3n://r.base.ihm/emr-log/")
.withServiceRole("service_role")
.withJobFlowRole("jobflow_role")
.withInstances(new JobFlowInstancesConfig()
.withEc2KeyName("emr")
.withEc2SubnetId("subnet-d1fbb8ee")
.withInstanceCount(3)
.withKeepJobFlowAliveWhenNoSteps(false)
.withMasterInstanceType("m4.large")
.withSlaveInstanceType("m4.large"));
RunJobFlowResult result = emr.runJobFlow(request);
}
}
but still I'm getting the error
java.lang.NoClassDefFoundError
{
"errorMessage": "Error loading class com.ihm.base.spark.CreateCluster: com/amazonaws/auth/AWSCredentials",
"errorType": "java.lang.NoClassDefFoundError"
}
Any ideas on what I am missing here?

import com.amazonaws.services.dynamodbv2.document.DynamoDB; the document part of the import cannot be resolved

I tried to update my dynamodb using aws but I am not able to create a dynamodb object or a table object as the import com.amazonaws.services.dynamodbv2.**document**.* does not register document but it reads all the other imports:

I had a similar problem and what I've learned is that the availability of, and/or source repositories for, packages can change over time.Therefore, if an import cannot be resolved, the following procedure may help.
Identify the package that supplies the dependency.
Locate a source for the package.
Configure the source with Gradle or Maven.
For my answer, I verified your desired imports against com.amazonaws:DynamoDBLocal:1.11.477 under Kotlin.
From the artifact page at MVNRepository, I selected View All.
This led me to a repository source with the following URL:
https://repository.mulesoft.org/nexus/content/repositories/public/com/amazonaws/DynamoDBLocal/1.11.477/
Since I was using Kotlin, I added the corresponding repository data to repositories in my build.gradle.kts for Gradle.
// Local DynamoDB.
repositories {
maven(url = "https://repository.mulesoft.org/nexus/content/repositories/public")
}
dependencies {
implementation ("com.amazonaws:DynamoDBLocal:1.11.477")
}
These imports, for the non-local case, can also be satisfied from the package at:
http://central.maven.org/maven2/com/amazonaws/aws-java-sdk-dynamodb/1.11.564/
Therefore, the following entries also work:
// Remote DynamoDB.
repositories {
mavenCentral()
}
dependencies {
implementation("com.amazonaws:aws-java-sdk-dynamodb:1.11.564")
}
After configuring my project for either the local or remote versions, I was able to verify that all of your imports that include "document" were available.

I'm assuming you probably tried this already, but it worked for me so I'm going to mention it anyway: I made sure that the AWS SDK for Java library had been added and then I refreshed the project. Now all is working!
I closed my project down and reopened it many times with no success, but refreshing the project did the trick. Good luck.

Can't run XML parser Jackson on Android

Can't run XML parser Jackson on Android
import android.content.Context;

public static class Channel {
public List<Item> channel;

public static class Item {
#JacksonXmlProperty(localName = "item")

Error is :
java.lang.NoClassDefFoundError: Failed resolution of: Ljavax/xml/stream/XMLInputFactory;
Caused by: java.lang.ClassNotFoundException: Didn't find class "javax.xml.stream.XMLInputFactory" on path: DexPathList

Old question but...
Android doesn't have the javax.xml.stream package, which is required for most libraries involving XML.
To add this yourself, add this dependency to your build.gradle file:
compile group: 'javax.xml.stream', name: 'stax-api', version: '1.0-2'
This is the latest release as of writing this comment. You can check here for updated versions.

You didn't setup Jackson for Android correctly. Look at this page Using jackson-dataformat-xml on android. There are good description how to do it.
