AWS IoT 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.

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.

Mac-Only TLS Behavior

Please note that on Mac, once a private key is used with a certificate, that certificate-key pair is imported into the Mac Keychain. All subsequent uses of that certificate will use the stored private key and ignore anything passed in programmatically. When a stored private key from the Keychain is used, the following will be logged at the "info" log level:

static: certificate has an existing certificate-key pair that was previously imported into the Keychain.  Using key from Keychain instead of the one provided.

Installation

Minimum Requirements

• Java 8 or above

** Set JAVA_HOME first

Requirements to build the AWS CRT locally

• CMake 3.1+
• Clang 3.9+ or GCC 4.4+ or MSVC 2015+

Build IoT Device SDK from source

git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
# update the version of the CRT being used
mvn versions:use-latest-versions -Dincludes="software.amazon.awssdk.crt*"
mvn clean install

Build CRT from source

# NOTE: use the latest version of the CRT here

git clone --branch v0.4.20 https://github.com/awslabs/aws-crt-java.git

git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
cd aws-crt-java
mvn install -Dmaven.test.skip=true
cd ../aws-iot-device-sdk-java-v2
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.

git clone --recursive --branch v0.6.2 https://github.com/awslabs/aws-crt-java.git
git clone https://github.com/awslabs/aws-iot-device-sdk-java-v2.git
cd aws-crt-java/android
./gradlew connectedCheck # optional, will run the unit tests on any connected devices/emulators
./gradlew publishToMavenLocal
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:0.6.2'
}
