Worklight - EncryptedCache open fails with error status 10 - ibm-mobilefirst

Question

I am having some problems with EncryptedCache on my HTC One Android phone.
The same code works on another phone and in the browser simulator but fails on my HTC One android phone with an unusual error code.
I am using: Worklight 6.2
Failing on: HTC one, android 4.4.2 (Cyanogenmod)
Working on: Samsung I9100 Galaxy S II
Working on: browser simulator
WL.EncryptedCache.open fails on my phone and return status 10..
(* WL.EncryptedCache.write fails on my phone and return status 6..)
I have also run the sample app from developerworks as-is on my HTC One phone with the same results and error code.
Sample app link
Logcat log:
Captured from Sample app
1) Destroyed cache
2) Entered a new key
3) Opened cache
4) Got alert error message
Full log can be downloaded from here
My code is:
function wlCommonInit(){
var STORAGE_ID = 'todos';
WL.EncryptedCache.open(STORAGE_ID, true,
function(){ //success
console.log('--> cache opened');
console.log("--> Loading Angular");
angular.element(document).ready(function() {
angular.bootstrap(document, ['todomvc']);
//location.hash = "/";
});
},
function(status){ //fail
console.log("WL.EncryptedCache open error status: " + status);
switch(status){
case WL.EncryptedCache.ERROR_KEY_CREATION_IN_PROGRESS:
alert("ERROR: KEY CREATION IN PROGRESS");
break;
case WL.EncryptedCache.ERROR_LOCAL_STORAGE_NOT_SUPPORTED:
alert("ERROR: LOCAL STORAGE NOT SUPPORTED");
break;
case WL.EncryptedCache.ERROR_NO_EOC:
alert("ERROR: NO EOC");
break;
case WL.EncryptedCache.ERROR_COULD_NOT_GENERATE_KEY:
alert("ERROR: COULD NOT GENERATE KEY");
break;
case WL.EncryptedCache.ERROR_CREDENTIALS_MISMATCH:
alert("ERROR: CREDENTIALS MISMATCH");
break;
default:
alert("AN ERROR HAS OCCURED. STATUS :: " + status);
}
});
}

Answer 1

Sorry to say I cannot currently reproduce this.
Installed Worklight Studio 6.2 from the Eclipse marketplace into a fresh copy of Eclipse and a new workspace
Downloaded the Encrypted Offline Cache sample project > import to Eclipse
Added the Android environment and > Run As > Run on Worklight Development Server
Installed on device (Nexus 5, Android 4.4)
Opened a cache, encrypted some value, closed cache, quit app, re-open, re-open cache, decrypt key, etc etc... all operations seem to pass.
Could you please use Wireshark while you use the app and provide the trace log from there?
In addition, if you could also try the above steps.

I too was getting the same error. My steps were open cache, write, close. Then open again and read.
The issue was close and open again. I kept the cache open for the entire session and it worked fine.
Looks like when you destroy cache, you might have to close it and open again to write a new entry.
Hope it helps.
