App in Google play without the 'delta' directory

[rbahumi]

Regardless of how stupid I feel for getting into this scenario, this is the way things are right now and I need a solution...

I have uploaded a few versions to the Google play store without the 'Delta' directory - which means that upgrading the App does actually nothing, because all files remain at the previous version in localStorage.

The solution I need is creating an update that will clear the localStorage and reload the APP.
Is there any simple way of doing that?

One solution I have tried is using the index.html file. It is never cached ( index.html is included in the HTML manifest ), therefore an inline javascript code can be added to it. I have the following code that clears the local storage on the first time it is being loaded:

if (typeof localStorage.deltafix == 'undefined') {
    localStorage.clear();
    localStorage.deltafix = true;
    window.location.reload();
}

The problem is it asks the user to confirm a different Checksum for app.js and app.css files (snapshots are attached).
Any idea how to prevent that from happening?

I have edited the microloader/development.js file to ignore the confirm message and that prevents the confirm alert...
I am not happy with that solution - but it works (My app doesn't use external JS files - so this solution is safe.) :

if (remoteChecksumBlock !== '/*' + version + '*/') {
  console.log('found a checksum missmatch - ignoring...');
  /* // commented out the confirm alert
  if (confirm("Requested: '" + asset.uri + "' with checksum: " + version +
    " but received: " + remoteChecksumBlock.substring(2, version.length) +
    "instead. Attempt to refresh the application?")) {
    refresh();
  }*/
  refresh(); // call refresh() automatically.
  return;
}

UPDATE:
My previous solution didn't work with IOS because of some external Phonegap plugins that were collapsing...

What make's this a bit harder, is the fact that even the app.json file is cached in localStorage - so I can't set the 'update: full' settings for app.css & app.js files.

I am now trying to remove the app.json file from local storage, and load a new one.
Is there a way of simply? Anyone?

Ok, found a way to go around this issue, and clear app.json, app.js and app.css from local storage of the production build. This is done by modifying the source code of touch/microloader/production.js :


1. Adding a single new line to getManifestStorageKey() function:

function getManifestStorageKey(id) {
  documentUri = documentUri.replace('index.html', ''); // for some reason, the file name in localStorage was index.htmlapp.json, so this fixes that
  return id + '-' + documentUri + manifestFile;
}

2. Adding a single-time procedure to Ext.blink(). The procedure resets all the localStorage entries that contains the ManifestStorageKey string:

Ext.blink = function(manifest) {
  
  /* NEW ADDED CODE */
  var mykey = 'JsonOverriden'; //define some uniqe key
  var JsonOverriden = retrieve(mykey); // retrieve(key) is basically: localStorage.getItem(key);
  var manifestStorageKey = getManifestStorageKey(manifest.id);


  if (!JsonOverriden){
    for (i in localStorage){
      var id = manifest.id;
      if (i.indexOf(id) != -1 )
        localStorage.removeItem(i)
    }


    store(mykey, true); // save a flag (mykey) localStorage, so this procedure runs only once
    documentLocation.reload();
    return;
  }
  /* END OF ADDED CODE */

  var manifestContent = retrieve(manifestStorageKey);


  writeMeta('viewport', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no');
  writeMeta('apple-mobile-web-app-capable', 'yes');
  writeMeta('apple-touch-fullscreen', 'yes');


  if (manifestContent) {
    manifest = new Manifest(manifestContent);
    blinkOnDomReady(manifest);
 } else { 
    requestXhr(manifestFile, function(content) {
      manifest = new Manifest(content);
      manifest.store();
      blinkOnDomReady(manifest);
    });
  }
};
