Integrating the EMV Core SDK into an Android environment allows for pre-certified EMV payment processing within a Kiosk or POS application. This guide covers the system requirements and the step-by-step installation process for the version.

​
System Requirements and SDK Files

Before beginning, ensure the host hardware meets the following criteria:
  • Android OS: Version 7 or above.
  • Network: Stable internet communication with TLS v1.2 or above.
  • Permissions: The application must have permission to read /sys/class.
  • SDK Package Components:
    1. com.nayax.emvCore-release-v.v-bbb.apk: The mandatory EMV-Core service package.
    2. com.nayax.emv_core_android_test-release-v.v-bbb.apk: The sample application used for testing.
    3. emv-core-test-v.v-bbb.zip: An Android Studio project containing a library and sample source code in Java.

​
Installation Steps

Follow these steps to install the SDK on Android:
  1. Deploy APKs: Install the EMV-Core Service package followed by the Test application on the target Android device.
  2. Hardware Connection: Connect the UNO reader to the Android device.
  3. System Prompts:
    • When the system prompts you to “Allow EmvCore Service to access Saturn 8700,” check the “Always open…” box and press OK to whitelist the reader.
    • Select Allow on the “Stop optimizing battery usage” prompt to keep the service running in the background.
  4. Restarting: If communication issues occur between the reader and the application, restart the service.

​
Verification

Once the applications are running and the reader is connected, the status line at the top of the test application screen should display “Ready”. You can then navigate to the ‘Maintenance’ page and press ‘Get Data’ to retrieve software versions and hardware status.
