Cordova is a cross-platform product. PSPDFKit SDKs are highly optimized and refined for a specific platform, to offer the best possible user experience. You can support both iOS and Android with your Cordova app as we offer plugins for both of these major mobile platforms. The configuration and setup is similar, but not the same, as each platform works different.
We offer wrappers for both our iOS and Android SDK. The philosophy here is that our wrapper/binding layer is open source and offers the most commonly needed customization options. If your requirements are not met, you can dig in and extend our wrapper, or even send a pull request.
