I am using Worklight 6.0.0.2 for JSONStore-related fixes in Android 4.4 "KitKit".
It works fine except for one issue: after a Direct Update the application restarts but then the JSONStore initialization fails; if we then quit the application and relaunch then it works well.
Steps for reproduction the issue in android 4.4. "KitKat":
Allow application to launch it self after updating
Then you see in LogCat:
05-13 16:28:57.010: E/jsonstore-core(16691): Error validating schema 05-13 16:28:57.010: E/jsonstore-core(16691): java.lang.Throwable: node with name "_id" already exists in schema 05-13 16:28:57.010: E/jsonstore-core(16691): at com.worklight.androidgap.jsonstore.database.DatabaseSchema.addNode(DatabaseSchema.java:124)
Inside initoptions.js
var wlInitOptions = {

pretty : false,

Inside JS file:
function wlCommonInit(){
collections["Videos"] = {
searchFields:{"BrandID":"string","VideoType":"string","CategoryID":"string","CourseID":"string","ISDeleted":"string","IsDownload":"string","VideoID":"string"}
};
var options = {"username":"*","password":"*","localKeyGen":false,"clear":false};
WL.JSONStore.init(collections, options)
.then(function (resp) {

connectToServer();
// initializeAnalytics(2000,131);
var query={"IsDownload":"2"};
WL.JSONStore.get('Videos').find(query, {exact:true})
.then(function (result2) {
if(result2.length > 0){
for(var i=0; i<result2.length; i++){
result2[i].json.IsDownload = 0;
Videos.replace(result2[i], {})
.then(function (numberOfDocumentsReplaced) {
WL.Logger.info("The number of document replaced are:--->"+numberOfDocumentsReplaced);
})
.fail(function (errorObject) {
WL.Logger.error("Error in document:---->"+errorObject);
});
}
}
errorvideodownloading();
})
.fail(function (errorObject) {
WL.Logger.debug('error' +errorObject.toString());
});
})
.fail(function (errorObject) {
WL.Logger.error("init notification error:----->"+errorObject);
if(errorObject.err === -2){
WL.Logger.error("In the errorObject so destroying JSON store and recreating it.");
WL.JSONStore.destroy();
JsonStoreinit();
localStorage.clear();
connectToServer();
}
else if(errorObject.err === 16)
{
hideSplashScreenPlatForm();
}
});
}
else{
WL.Logger.debug('[JSONStore] Check your dependencies.');
}
}catch(e){
WL.Logger.error("Exception is:--->"+e);
}
}
Am not sure about your init Code. But you will get error like
java.lang.Throwable: node with name "_id" already exists in schema
when you are using the collection until a successful callback.
