So, as I recall, you need to use an SVirtualKeyboardEntry widget instead of SEditableTextBox. But there’s a bigger problem which is that we actually haven’t implemented the bits on Android yet (an oversight, we’ve never actually needed virtual keyboard yet!)
I will add a task for this to be done soon, but if you want to have a go, check out FIOSPlatformTextField, that is what needs to be done for Android.
