Share localStorage via webView and CordovaWebView android
I am trying to communicate in activity between webView and CordovaWebView. The CordovaWebView is of course using a webView and therefore I don't understand why the data stored in localStorage in my phoneGap app is not visible in a simple web browser that loads the html page from the same location as the main app. I already researched that the data stored in the CordovaWebView is stored in the file / app_webview / Local Storage / file__0.localstorage , and the data stored in the created webView instance is stored in the file / app_webview / Local Storage / __ 0.localstorage , so I can't access data. I am loading script storage data in localStorage in webView like this:
webView.loadUrl("file:///android_asset/www/script.html");
The master page in the CordovaWebView is loaded in the same way:
void loadUrlNow(String url) {
if (LOG.isLoggable(LOG.DEBUG) && !url.startsWith("javascript:")) {
LOG.d(TAG, ">>> loadUrlNow()");
}
if (url.startsWith("file://") || url.startsWith("javascript:") || Config.isUrlWhiteListed(url)) {
super.loadUrl(url);
}
}
where url
file:///android_asset/www/index.html
So why in CordovaWebView localStorage is stored in file
/app_webview/Local Storage/file__0.localstorage
And in webview in file
/app_webview/Local Storage/__0.localstorage

Unfortunately, the strange behavior of localStorage on Android is intentional. You can fix the problem on the native side using a library like this (haven't tried it myself):
Or you can use JavaScript to populate localStorage using the executeScript parameter when you open the InAppBrowser and read localStorage when you close it.
This works well for small amounts of data. It can be quite frustrating to debug large amounts.
