IBM MobileFirst 7.1 with Android Cordova failure w

I am trying to create a 'heloworld' project with IBM Mobilefirst 7.1 integrate cordova using platform android and enable feature JSONStore

Step 1: create mobilefirst cordova project flowing link https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/7.1/hello-world/integrating-mfpf-sdk-in-cordova-applications/#sampleApplication
Note: platform android and add more plugin jsonstore
Step 2: add feature JSONStore in application-descriptor.xml

Step 3: add code in function wlCommonInit

WL.JSONStore.init(collections).then(function (collections) {
    // handle success - collection.people (people's collection)
    console.log('ok')
}).fail(function (error) {
    // handle failure
    console.log('error', error)
});

Step 4: build and run with Android studio with Android Emulator - Nexus_4_API_19, I get error of console.log('error', error)
```
col: "people"
doc: Object
err: -1
msg: "PERSISTENT_STORE_FAILURE"
res: Object
src: "initCollection"
usr: "jsonstore"
```
