AWS SQS connection problem

Answer 1

I suggest to use the AWS Java SDK V2 . It will allow you to use an alternate HTTP runtime, and avoid some of the mess with the Apache client, when working on Android.

GitHub Issue #1180 in the AWS Java SDK V2 repo addresses this topic.

Specifically, in your module-level build.gradle , add dependencies:

dependencies {
    implementation 'software.amazon.awssdk:sqs:2.13.49'
    implementation 'software.amazon.awssdk:url-connection-client:2.13.49'
}

Now, initialize the SQS client:

val sqs = SqsClient.builder()
    .httpClient(UrlConnectionHttpClient.create())
    .region(Region.US_EAST_1)
    .credentialsProvider(yourCredentialsHere())
    .build()

Answer 2

its working.

     ProfileCredentialsProvider credentialsProvider = new ProfileCredentialsProvider();

    try {

        credentialsProvider.getCredentials();
    } catch (Exception e) {
        throw new AmazonClientException(
                "Cannot load the credentials from the credential profiles file. " +
                        "Please make sure that your credentials file is at the correct " +
                        "location (~/.aws/credentials), and is in valid format.",
                e);

    }
    AmazonSQS sqs = AmazonSQSClientBuilder.standard()
            .withCredentials(credentialsProvider)
            .withRegion(Regions.US_WEST_2)
            .build();
