Hi,

i'm new to visa, and trying to integrate Visa SDK for android, the sample can successfully run at my android studio. But when I copy the function to my current Payment Class, this error appear when i click visa payment button.

Here is the complete message :

We have been working on the error that you have highlighted . To take this further , need a few more details

  • What version of Visa Checkout SDK are you using?
  • What is the version of the device OS?
  • Is the device a rooted phone?
  • Snippet of vInit configuration? (Hint: probably didn’t add the merchant api key)
  • app Activity or Fragment code snippet where you are trying to initialize the SDK?

    • Hi,

    1. Visa 3.5

    2. Device OS is vary from jellybean to marshamallow

    3. Also vary, have rooted and non-rooted too. Tested on both.

    4.

    I still use code from sample :

    I copy the whole sample into my app, and the sample code can run.

    But when integrating into my activity, got that error.

    Below is the code :

    Spoiler

    Thank you for the inputs. We are working on this question and looking for a couple of more details

  • Need code snippet used for SDK initialization
  • Version of Android VCO SDK version
  • Gradle version and build tool version used
  • Manifest file configuration

    • Hi,

    1. Need code snippet used for SDK initialization 

        private void initializeVisaCheckoutSdk() {
        VisaEnvironmentConfig visaEnvironmentConfig = VISA_CHECKOUT_ENVIRONMENT_CONFIG;
        /** Optional: a non-empty profile name obtained during enrollment can be included here. */
        visaEnvironmentConfig.setMerchantProfileName(VISA_CHECKOUT_PROFILE_NAME);
        /** Required. Merchant API key obtained after enrollment. */
        visaEnvironmentConfig.setMerchantApiKey(VISA_CHECKOUT_API_KEY);
        /** Required for EXOButton integration only. Optional for VisaPaymentButton and CustomView integration.
         *  RequestCode to start SDK activity with, may be used in onActivityResult() as indicator that result came from the SDK. */
        visaEnvironmentConfig.setVisaCheckoutRequestCode(VISA_CHECKOUT_REQUEST_CODE);
        /** getLibrary should be invoked when the activity/application is created. getLibrary initializes the SDK
         in the background and makes the launch faster when user clicks the checkout button/view.  */
        visaMcomLibrary = VisaMcomLibrary.getLibrary(this, visaEnvironmentConfig);
    }

    2. Version of Android VCO SDK version -> version 3.7 (the latest)

    3.Gradle version and build tool version used -> gradle 2.0.0 & 

    buildToolsVersion = "21.1.2"

    4.Manifest file configuration

        <!-- Activities responsible for gathering payment info via card.io -->

                  android:configChanges="keyboardHidden|orientation"
                  android:screenOrientation="portrait"
                  android:hardwareAccelerated="true" />
        <activity android:name="io.card.payment.DataEntryActivity"
                  android:screenOrientation="portrait" />
    </application>
</manifest>

    After going through the details and comparing the scenario across different use cases, the potential reasons for the behavior could be that the values that are mandatory for SDK initialisation not present (need to pass all mandatory files in VisaPayment and MerchantInfo Object)

    We would recommend the following and revert

  • Check if sample app works with all the configuration ( API key, supported cards, billing address and shipping address configuration etc., )
  • Compare the Developer app with sample app to make sure SDK in initialized correctly
