Import the following classes in your Activity/Fragment

Code Block

language	kotlin

import com.sondeservices.passive.enrollment.EnrollmentCallback
import com.sondeservices.sonde_passive.enrollment.EnrollmentHandler
import com.sondeservices.passive.enrollment.IEnrollmentapplication_api.init.SondePassiveSdk

Before starting the Enrollment, add the next check to make sure that the RECORD_AUDIO permission is enabled in your app:
Declare the following code.

...

Then add the following check,

Code Block

language	kotlin

if (ContextCompat.checkSelfPermission(
        requireContext(),
        android.Manifest.permission.RECORD_AUDIO
    ) != PackageManager.PERMISSION_GRANTED
) {
    val permissions = arrayOf(android.Manifest.permission.RECORD_AUDIO)
    ActivityCompat.requestPermissions(
        requireActivity(),
        permissions,
        REQUEST_CODE_RECORD_AUDIO
    )
}

...

Code Block

override fun onRequestPermissionsResult(
  requestCode: Int,
  permissions: Array<String>,
  grantResults: IntArray
) {
  super.onRequestPermissionsResult(requestCode, permissions, grantResults)

  if (requestCode == REQUEST_CODE_RECORD_AUDIO && grantResults.isNotEmpty()
      && grantResults[0] != PackageManager.PERMISSION_GRANTED) {
    throw RuntimeException("Record Audio permission is required to start recording.")
  }
}

Declare IEnrollment in the declaration section of Activity/Fragment,

private var enrollmentHandler: IEnrollment? = null

...

Create enrollmentHandler and call the beginEnrollment() function to start Enrollment.

enrollmentHandler = EnrollmentHandler.createEnrollment

Code Block

language	kotlin

SondePassiveSdk.createEnrollmentHandler(requireContext())

enrollmentHandler?SondePassiveSdk.beginEnrollment(
      object : EnrollmentCallback {
          override fun finishEnrollment() {
            //Get
callback
here when Enrollment gets finished.           }

          override fun onEnrollmentSuccess() {
              Log.d(TAG, "onEnrollmentSuccess==>")
              Snackbar.make(requireView(), "Enrollment Successful", Snackbar.LENGTH_LONG)
                  .setAction("Action", null).show()      
          }

          override fun onSecondCaptured(seconds: Int) {
              //Get the callback to show user how much seconds of active voice enrolled out of 10 seconds.
              Log.d(TAG, "onSecondCaptured==>$seconds")
          }
          override fun onMessage(message: String) {
              //Get callback when there is any message like background noise in enrollment.
          }
          
          override fun finishEnrollment() {
            //Get callback here when Enrollment gets finished.
          }
          
          override fun onError(throwable: Throwable) {
              //Get callback for all type of errors
              throwable.printStackTrace()
          }
      }
  )

During enrollment, the following messages may be generated based on the enrollment audio analysis:

Background noise - The message will be generated if there is background noise in the first 10 20 seconds of the audio. The user must be informed, “High background noise detected; please move to a quieter location.”
