Step 1: Open project file

  1. Open the Android Studio.

  2. Click on the Open an existing Android Studio project option. If mastercard-sharehome-android project is already open, jump to 5.

  3. If some other project is already open, click File -> Open.

  4. Open the mastercard-sharehome-android project.

    • For Windows workstation: C:\{APP_DIRECTORY}\ShareHome\mastercard-sharehome-android

    • For Linux workstation: ./{APP_DIRECTORY}/ShareHome/mastercard-sharehome-android

  5. Wait a couple of minutes until the whole project is loaded.

Step 2: Code implementation

  1. Initiate requests for scopes when user clicks Continue with ID button.

    • Analyze the application flow and find in source code the place to put the corresponding code fragment

    • Use RPClaimRequestBuilder class to create request with proper scopeType

    • Test if there is a proper result redirecting to Samsung Pass application


    override fun onCreate(savedInstanceState: Bundle?) {
            .setOnClickListener(View.OnClickListener {
            RPClaimRequestBuilder().requestForScopes(this, ScopeType.NameAddressDoB)

  2. Handle the response with requested scope from Samsung Pass application.

    • Find usage of method handlerScopeResponse

    • Fill callback, so that requested scopes are combined as single String separated with \n

    • Forward result to PaymentActivity class. Use intent.putExtra with key "ReturnedScope"

    • Check if PaymentActivity shows requested data


    override fun onCreate(savedInstanceState: Bundle?) {
        if (intent.action == Intent.ACTION_VIEW) {
            ( as? Uri)?.let {
                RPClaimResponseParser().handlerScopeResponse(this, it, { scopes ->
                    val scopeDetails = { scope -> scope.value }.joinToString { "\n" + it }
                    var intent = Intent(this,
                    intent.putExtra("ReturnedScope", scopeDetails)
        } else {
            Handler().postDelayed(Runnable {
                val intent = Intent(this,
            }, 1000)

Step 3: Deployment

  1. In the top menu bar click: Build -> Make project.

  2. Connect the Samsung Galaxy device to the workstation via USB. Click Allow if you see a pop-up on the Galaxy device.

  3. Run the project.

  4. Select the Galaxy device as a deployment target. Do not deploy the project on any emulator. Click the OK button.

  5. The project has been deployed on the Galaxy device.

  6. Close the mastercard-sharehome-android project: File -> Close Project.
