Obtaining the Measurement Results

After the upload of your scanned frames is completed (that is, the TireTreadScanView's callback method onUploadCompleted was invoked), your measurement results may still take a few seconds to become available. To fetch the results, call the function getTreadDepthReportResult(measurementUuid):

class MeasurementResultActivity(
    private val backgroundDispatcher: CoroutineDispatcher = Dispatchers.IO
) : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {

        var measurementUuid: String = ""

        val bundle = intent.extras
        bundle?.also {
            measurementUuid = it.getString("measurement_uuid") ?: ""

        // Display some "loading" information

        // Run the fetchResults in a background thread
        lifecycleScope.launch(backgroundDispatcher) {

    private fun fetchResults(measurementUuid: String) {
        Log.d("MY_APP", "Checking for results for UUID - $measurementUuid - ...")

            onGetTreadDepthReportResultSucceeded = { result: TreadDepthResult ->
                Log.d("MY_APP", "$measurementUuid result is available")
                runOnUiThread {
            onGetTreadDepthReportResultFailed = { measurementError: MeasurementError ->
                // Handle failure
                Log.e("MY_APP", "$measurementUuid failed")
                Log.e("MY_APP", "Error Code: ${measurementError.errorCode}")
                Log.e("MY_APP", "Error Message: ${measurementError.errorMessage}")
                runOnUiThread {

Once the result is available, the onGetTreadDepthReportResultSucceeded callback will be called with the TreadDepthResult object containing it.

In case of any failure, the onGetTreadDepthReportResultFailed will be called containing the MeasurementError object, where you can find the error code and message.

A timeoutSeconds parameter can also be passed to the function, limitting for how long the result fetching can run before being interrupted (in case of bad network connection, etc.).

PDF Report

To retrieve the PDF report of a measurement, you can poll the function getTreadDepthReportPdf(uuid) from the AnylineTireTreadSdk class every 3 seconds, until the PDF is available and returned as a byte array. The return value can then be saved and displayed as best fitting your application’s workflow, e.g.:

try {
    AnylineTireTreadSdk.getTreadDepthReportPdf(uuid, { pdfData ->
        // Create a temporary file
        val tmpPdfFile = File.createTempFile("ttr_report-", ".pdf")

        // Write the PDF data into it
        val fos = FileOutputStream(tmpPdfFile)

        // Prepare to show
        val browserIntent = Intent(Intent.ACTION_VIEW)
        val uri = FileProvider.getUriForFile(
        browserIntent.setDataAndType(uri, "application/pdf")

        val chooser = Intent.createChooser(browserIntent, "Open with")
        chooser.flags = Intent.FLAG_ACTIVITY_NEW_TASK

    }, { exception ->
        Log.e("Showcase", "Exception raised while loading the PDF", exception)
            this, "The detailed report cannot be displayed at the moment.", Toast.LENGTH_SHORT
} catch (e: Exception) {
    Log.e("MY_APP", "PDF Report issue: ", e)

Remember to try/catch the getTreadDepthReportPdf() function, as the PDF report may not yet be available.

The PDF report will only be available if the TreadDepthResult was previously available, so the best workflow is to first check for results, and only then try to obtain the PDF report.

User Corrected Values and Comments

User Comments

To send a comment on a measurement, use the sendCommentFeedback function of the AnylineTireTreadSdk.

As usual with the TireTreadSDK, the UUID for the scan must be passed as a parameter. The comment is passed as a string, e.g.:

AnylineTireTreadSdk.sendCommentFeedback(measurementUuid, commentText,
        onSendCommentSucceed =  {
                resources.getString("Send comment: Success"),
        onSendCommentFailed = { _, e ->
                resources.getString("Send comment: Failure"),

User Corrected Region Values

To send user corrected region values, use the sendTreadDepthResultFeedback function from the AnylineTireTreadSdk. The result feedback should be provided as a list of TreadResultRegion, ordered from left to right.

You can only provide feedback for the regions returned by the SDK in the TreadDepthResult object.

The values of all regions need be added to the list before sending the feedback.

The TreadResultRegion objects can be initialized with Millimeters or Inches, e.g.:

val regionMm = TreadResultRegion.initMm(true, 1.2)
val regionInch = TreadResultRegion.initInch(true, 0.047)

val myCorrectedResults: List<TreadResultRegion> = listOf(regionMm, regionInch)

AnylineTireTreadSdk.sendTreadDepthResultFeedback(measurementUuid, myCorrectedResults,
            { Log.i("SHOWCASE", "Send result success.") },
            { _, e -> Log.e("SHOWCASE", "Send result failed.", e) })
