Android SDK

The SDK is available for all languages. See individual language for installation instructions.

Android Sample Application

The Trinsic Android sample application makes it easy to interact with the Trinsic API. The sample application is located here

Installation

  1. Clone the sdk-examples repository
  2. Open the folder sdk-examples/android in Android Studio
  3. Run gradle build for the first time, it will take a while, but it should pull down all the required .jar files
  4. You should be able to build and run the android application.
  5. There is an sdk-examples/android-controller application written in Python which allows you to issue credentials/verify proofs outside of the android application for demonstration purposes.

Note

If you want to included 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}")
    file.parentFile.mkdirs()
    if (!file.exists()) {
        new URL(url).withInputStream { downloadStream ->
            file.withOutputStream { fileOut ->
                fileOut << downloadStream
            }
        }
    }
    files(file.absolutePath)
}

dependencies {
    // other dependencies
    implementation urlFile('https://github.com/trinsic-id/sdk/releases/download/v1.13.0/trinsic-services-1.10.0.jar', 'trinsic-services-1.13.0')
    // You can change these versions if needed, but they are dependencies of the above jar file
    implementation("io.grpc:grpc-netty-shaded:1.60.0")
    implementation("io.grpc:grpc-okhttp:1.60.0")
    implementation("io.grpc:grpc-protobuf:1.60.0")
