Capturing Videos

To start recording, use thestartActivityForResult method:

val intent = OzLivenessSDK.createStartIntent(listOf(OzAction.Smile, OzAction.Blank))
startActivityForResult(intent, REQUEST_CODE)

List<OzAction> actions  = Arrays.asList(OzAction.Smile, OzAction.Scan);
Intent intent = OzLivenessSDK.createStartIntent(actions);
startActivityForResult(intent, REQUEST_CODE);

actions – a list of user actions while recording video.

For Fragment, use the code below. LivenessFragment is the Fragment representation of the Liveness screen UI.

childFragmentManager.beginTransaction()
    .replace(R.id.content, LivenessFragment.create(actions))
    .commit()
// subscribing to the Fragment result
childFragmentManager.setFragmentResultListener(OzLivenessSDK.Extra.REQUEST_CODE, this) { _, result ->
    when (result.getInt(OzLivenessSDK.Extra.EXTRA_RESULT_CODE)) {
        OzLivenessResultCode.SUCCESS -> { /* start analysis */ }
        else -> { /* show error */ }  
    }
}

getSupportFragmentManager().beginTransaction()
        .replace(R.id.content, LivenessFragment.Companion.create(actions, null, null, false))
        .addToBackStack(null)
        .commit();
// subscribing to the Fragment result
getSupportFragmentManager().setFragmentResultListener(OzLivenessSDK.Extra.REQUEST_CODE, this, (requestKey, result) -> {
            switch (result.getInt(OzLivenessSDK.Extra.EXTRA_RESULT_CODE)) {
                case OzLivenessResultCode.SUCCESS: {/* start analysis */}
                default: {/* show error */}
            }
        });

To obtain the captured video, use theonActivityResult method:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
  super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == REQUEST_CODE) {
      sdkMediaResult = OzLivenessSDK.getResultFromIntent(data)
      sdkErrorString = OzLivenessSDK.getErrorFromIntent(data)
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @androidx.annotation.Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE) {
        List<OzAbstractMedia> sdkMediaResult = OzLivenessSDK.INSTANCE.getResultFromIntent(data);
        String sdkErrorString = OzLivenessSDK.INSTANCE.getErrorFromIntent(data);
    }

sdkMediaResult – an object with video capturing results for interactions with Oz API (a list of the OzAbstractMedia objects),
sdkErrorString – description of errors, if any.

If you use our SDK just for capturing videos, omit the Checking Liveness and Face Biometry step.

If a user closes the capturing screen manually, resultCode receives the Activity.RESULT_CANCELED value.

Code example:

when (resultCode) {
    Activity.RESULT_CANCELED -> *USER CLOSED THE SCREEN*
    OzLivenessResultCode.SUCCESS -> {
        val sdkMediaResult = OzLivenessSDK.getResultFromIntent(data)
        *SUCCESS*
    }
    else -> {
        val errorMessage = OzLivenessSDK.getErrorFromIntent(data)
        *FAILURE*
    }
}
