"Could not validate your API Key, see your web dashboard for details"
This error often happens if your device is offline, or your package name does not match that in your dashboard. Check both your internet connection on your device, and the package name.
If neither of these solve the issue, try a fresh install of your app by first deleting and then reinstalling your APK on the device and double check that you're running the most up to date version of the SDK.
If you are still experiencing the issue, please reach out to support.
