This is a port of the official Node.js SDK to Kotlin. This can also be used from Java and any JVM language.
Quick Facts
- Port of the actions-on-google SDK to Kotlin. Kotlin and Java developers can quickly start building Actions for Google Assistant.
- Closely matches Node.js Client Library API
- Closely matches implementation of Node.js sdk so code can be maintained easily as features are added
- All tests ported from nodejs SDK (using Spek framework) & 100% passing
- Api.Ai and Actions SDK support
- Conversation Components & Transaction Sample ported
- Supports v2 of Actions on Google API (if v1 is needed, make an issue please)
This library is available on jCenter and Maven Central. If your using gradle simply add the dependency as follows:
Gradle:
repositories {
jCenter()
}
}
dependencies {
compile 'com.tmsdurham.actions:actions-on-google:1.2.1'
}
Maven:
<dependency>
<groupId>com.tmsdurham.actions</groupId>
<artifactId>actions-on-google</artifactId>
<version>1.2.1</version>
<type>pom</type>
</dependency>
The above artifact should fit the needs of most developers, however, if you are not using java.servlet.http.HttpServlet, or do not want to use Gson for deserialization, you can use the actions-on-google-core lib. For example how to use the core library, reading through the sdk-gson-servlet module.
Gradle:
compile 'com.tmsdurham.actions:actions-on-google-core:1.2.1'. //only if not using Servlets
Maven:
<dependency>
<groupId>com.tmsdurham.actions</groupId>
<artifactId>actions-on-google-core</artifactId> //only if not using Servlets
<version>1.2.1</version>
<type>pom</type>
</dependency>
