The Trinsic Java / Kotlin SDK

The Trinsic Java / Kotlin SDK makes it easy to interact with the Trinsic API from any Java (or Kotlin) application. The most recent version of the package is found on the Github Release. You can find the SDKs source on Github.


  1. Add the urlFile code shown below to your build.gradle.
  2. Add the implementations as shown below to your build.gradle.
  3. Run gradle build to download the required jar files. This can take some time.


  1. Okapi binaries are now included with the server .jar or the corresponding android .aar file. The gradle include process is essentially similar (see below).
  2. If you install to a different location for debugging, use the environment variable LD_LIBRARY_PATH, even on Windows.
  3. For Android, the okapi binaries must be copied (currently manually) to a specific location with a specific folder structure. The complete sample application is here


If you want to include the two required Trinsic .jar files in your own application (android or other java), be sure to copy the following lines. They allow you to specify a remote file location as a gradle implementation target as shown below:

def urlFile = { url, name ->
    File file = new File("$buildDir/download/${name}")
    if (!file.exists()) {
        new URL(url).withInputStream { downloadStream ->
            file.withOutputStream { fileOut ->
                fileOut << downloadStream
dependencies {
    // other dependencies
    implementation urlFile('', 'trinsic-okapi-1.6.2')
    // android version:
    // implementation urlFile('', 'trinsic-okapi-1.6.1')
    implementation urlFile('', 'trinsic-services-1.8.1')
