问题
When I played with the sample Using_JSONStore, I always tested WL.JSONStore=="undefined" on Android Mobile Browser Simulator or on a Android Virtual Device Emulator, or on my real Android device (Android version 2.3.5). How to enable the WL.JSONStore feature in the Worklight project? Thanks.
回答1:
In Worklight 5.0.6.x, JSONStore is always part of the Android and iOS environments, so it is always present. There is nothing to 'enable'.
What you want to do, is perhaps initialize it, that is - use the init method. Is that what you're after?
Please also consult with the JSONStore documentation.
