To integrate reCAPTCHA Enterprise, please follow the instructions for iOS and Android.
A critical security vulnerability was discovered in reCAPTCHA Enterprise for Mobile. The vulnerability has been patched in the latest SDK release. Customers will need to update their Android application with the reCAPTCHA Enterprise for Mobile SDK, version 18.4.0 or above. We strongly recommend you update to the latest version as soon as possible.
WARNING: Due to a bug described in Issue 52, some users may experience unrecoverable errors if you have used a version of the SDK < 18.2.0 and then upgrade to 18.2.0. Instead please upgrade directly to 18.2.1.
The basic example applications demonstrate how to implement the reCAPTCHA Enterprise score-based challenges in mobile applications. These implementations demonstrate best practices with init started at app startup, retries, and waiting for network connectivity.
The visual example applications demonstrate how to incorporate visual challenges into a mobile application using a webview.
