问题
I upgraded from Worklight 6.1.0.1 to 6.2 and since then, my app stopped loading JSONStore successfully.
It says it can't find the class StoragePlugin, although the class is actually there in the worklight-android.jar
It is also declared in the config.xml file:
<feature name="StoragePlugin">
<param name="android-package" value="com.worklight.androidgap.plugin.storage.StoragePlugin"/>
</feature>
That's the logcat output when I run it on a android device:

Any hint about what may be causing this?
回答1:
We just verified that this is an actual defect, we will be fixing it. The quick fix is to change com.worklight.androidgap.plugin.storage.StoragePlugin to com.worklight.androidgap.plugin.StoragePlugin (remove the ".storage." part) and it will work again.
