Next generation AWS IoT Client SDK for Java using the AWS Common Runtime

AWS IoT Device SDK for Java v2

This document provides information about the AWS IoT device SDK for Java V2.

If you have any issues or feature requests, please file an issue or pull request.

API documentation: https://aws.github.io/aws-iot-device-sdk-java-v2/

This SDK is built on the AWS Common Runtime, a collection of libraries (aws-c-common, aws-c-io, aws-c-mqtt, aws-c-http, aws-c-cal, aws-c-auth, s2n...) written in C to be cross-platform, high-performance, secure, and reliable. The libraries are bound to Java by the aws-crt-java package.

What's New

The SDK now supports MQTT5. See the MQTT5 User Guide or the API Documentation for more information. There is also a MQTT5 sample here.

Installation

Minimum Requirements

• Java 8+ (Download and Install Java)
• Java JDK 8+ (Download and Install JDK)
  • Set JAVA_HOME

Step-by-step instructions

Requirements to build the AWS CRT locally

• C++ 11 or higher
  • Clang 3.9+ or GCC 4.4+ or MSVC 2015+
• CMake 3.1+

Step-by-step instructions

Consuming IoT Device SDK from Maven in your application

Consuming this SDK via Maven is the preferred method of consuming it and using it within your application. To consume the Java V2 SDK in your application, add the following to your pom.xml dependencies:

<dependency>
  <groupId>software.amazon.awssdk.iotdevicesdk</groupId>
  <artifactId>aws-iot-device-sdk</artifactId>
  <version>1.13.0</version>
</dependency>

Replace 1.13.0 in <version>1.13.0</version> with the latest release version for the SDK. Look up the latest SDK version here: https://github.com/aws/aws-iot-device-sdk-java-v2/releases

Build IoT Device SDK from source

Install Maven and Set PATH

# Create a workspace directory to hold all the SDK files
mkdir sdk-workspace
cd sdk-workspace
# Clone the repository
git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
cd aws-iot-device-sdk-java-v2
# Compile and install
mvn clean install

If you wish to use the latest CRT release, rather than the latest tested with the IoT SDK, you can run the following before running mvn clean install:

# Update the version of the CRT being used
mvn versions:use-latest-versions -Dincludes="software.amazon.awssdk.crt*"

Build IoT Device SDK and CRT from source

# Create a workspace directory to hold all the SDK files
mkdir sdk-workspace
cd sdk-workspace
# Clone the CRT repository
#     (Use the latest version of the CRT here instead of "v0.21.14")
git clone --branch v0.21.14 --recurse-submodules https://github.com/awslabs/aws-crt-java.git
cd aws-crt-java
# Compile and install the CRT
mvn install -Dmaven.test.skip=true
# Clone the SDK repository
git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
cd ../aws-iot-device-sdk-java-v2
# Compile and install
mvn clean install

Android

Supports API 26 or newer. NOTE: The shadow sample does not currently complete on android due to its dependence on stdin keyboard input.

# Create a workspace directory to hold all the SDK files
mkdir sdk-workspace
cd sdk-workspace
# Clone the CRT repository
#     (Use the latest version of the CRT here instead of "v0.21.14")
git clone --branch v0.21.14 --recurse-submodules https://github.com/awslabs/aws-crt-java.git
# Compile and install the CRT for Android
cd aws-crt-java/android
./gradlew connectedCheck # optional, will run the unit tests on any connected devices/emulators
./gradlew publishToMavenLocal
# Clone the SDK repository
cd ../..
git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
# Compile and install
cd aws-iot-device-sdk-java-v2/android
./gradlew publishToMavenLocal
./gradlew installDebug # optional, will install the IoTSamples app to any connected devices/emulators

Add the following to your project's build.gradle:

repositories {
    mavenCentral()
    maven {
        url System.getenv('HOME') + "/.m2/repository"
    }
}

dependencies {
    implementation 'software.amazon.awssdk.crt:android:0.21.14'
}

Replace 0.21.14 in software.amazon.awssdk.crt:android:0.21.14 with the latest version of the CRT. Look up the latest CRT version here: https://github.com/awslabs/aws-crt-java/releases

Caution

You will need to override and provide a ROOT_CERTIFICATE manually from one of the following certificates. For overriding default trust store you can use following method. It's a known problem.
