Error handling

Resolve errors on the mobile Android device.

The Adyen payments platform performs regular checks to make sure that the mobile device that is used in a Mobile solution is secure.

If an issue is found during the security attestation process in an integration with the Android SDK, an error is shown on the mobile device. In many cases end users can resolve the issue themselves. The user needs to resolve the issue before trying to use the device again.

If an issue is found when using the Android Payments app, the error is shown on the mobile device or in the App link. The error usually needs to be fixed in the code.
