The ColdFusion Builder supports creating platform-specific builds for Android and iOS platforms. In order to package the mobile applications for these platforms, you need to configure the ColdFusion Builder to sign the applications with an appropriate developer/self-signed certificate. In the case of Android, providing the certificate details is optional as you can create an Android Application Package (APK) file for testing on your devices without signing it. However, testing the mobile application on iOS devices require you to have a developer certificate and a provisioning profile file.
