AWS CloudWatch Log on Android

Question

I'm trying to use AWS CloudWatch Log in an Android app. I have the following config for the aws-client:

val basicAWSCredentials = BasicAWSCredentials(
        “Xxxxxx”,
        “Yyyyyy”
)
val awsLogsClientBuilder = AWSLogsClientBuilder.standard()
awsLogsClientBuilder.region = Regions.EU_WEST_2.name
awsLogsClientBuilder.credentials = AWSStaticCredentialsProvider(basicAWSCredentials)
awsClient = awsLogsClientBuilder.build()

In the build.gradle I have

implementation ("com.amazonaws:aws-java-sdk-logs:1.11.367") {
    exclude module: 'joda-time'
}

The app is crashing at awsLogsClientBuilder.build() with the following exception:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.xxxxxx.xxxxx, PID: 28703 java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; or its superclasses (declaration of 'org.apache.http.conn.ssl.AllowAllHostnameVerifier' appears in /system/framework/framework.jar!classes2.dex)...

I have tried to use the android specific library as well:

androidSdkLogsVersion = "2.6.24"
implementation "com.amazonaws:aws-android-sdk-logs:$androidSdkLogsVersion"

and/or

implementation "com.amazonaws:aws-android-sdk-mobile-client:$androidSdkLogsVersion"

but if I use it along with the java sdk I get an error at compile time:

Program type already present: com.amazonaws.ResponseMetadata

If I do not import the java-sdk then I get an error at compile time because the class AWSLogsClientBuilder is not found anymore.

How should I create the logger on Android?

Answer 1

This is what I did:

In the build.gradle

androidSdkLogsVersion = "2.6.24"
implementation "com.amazonaws:aws-android-sdk-logs:$androidSdkLogsVersion"

and to configure the logger:

val basicAWSCredentials = BasicAWSCredentials("xxxxx","yyyy")
val awsClient = AmazonCloudWatchLogsClient(basicAWSCredentials)
val regions: Regions = Regions.EU_WEST_1
awsClient.setRegion(Region.getRegion(regions.getName()))

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.

In your module-level build.gradle , add dependencies:

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

Now, initialize the CloudWatch client:

val cloudwatch = CloudWatchClient.builder()
    .httpClient(UrlConnectionHttpClient.create())
    .region(Region.US_EAST_1)
    .credentialsProvider(yourCredentialsHere())
    .build()
