Worklight 6.1: JSONStore initialization issue on Android 4.2.2

Question

Environment:

Worklight 6.1

Samsung Tab 3

Android 4.2.2

Code to initialize JSONStore -

var collections = {};
collections["SampleApp"] = {};
collections["SampleApp"].searchFields = {uName: 'string', uPassword: 'string'};

var options = {};
options.username = "offlineUser";
options.password = "psw12345";
options.localKeyGen = true;
options.clear = false;

WL.JSONStore.init(collections, options)
.then(function () {
    WL.Logger.debug("Successfully initialized JSON Store");
})
.fail(function (errorObject) {
    WL.Logger.debug("Error while initialing JSON Store - " + errorObject);
});

I am getting following exception while initializing JSONStore -

Please let me know, if more data required from my side. Any help will be much appreciated.

Answer 1

The exception was occurring because of the missing guava.jar file on the build machine -

/apps/SampleApp/android/native/libs/guava.jar

which got generated after an upgrade from Worklight 6.0 to 6.1.

We have followed the worklight doc - Integrating with source control systems which doesn't mention anything about "libs" folder and hence didn't checked-in the file.

Now build machine takes whatever checked-in and builds the APK file. The generated APK file doesn't contain "guava.jar" file, which contains package "com.google.common.collect.Maps". And hence we were seeing the issue.

Note: We were seeing the issue after adding changes to use JSONStore. So it looks like JSONStore use this package.
