cordova - Is local storage for a Phonegap app on an Android device separate from the built in browser?

Question

My question is essentially a follow up or clarification to this question.

I have an Android app built using Javascript and Adobe's Phonegap Build service, and I'm using "local storage" to store data on the device.

From that other question, I learned that data stored in local storage is essentially "permanent", in that it will stay on the device indefinitely, unless the user acts on it by manually clearing the cache for the app or deletes the app (and maybe other unusual circumstances that I'm willing to live with).

However, part of the accepted answer was confusing to me in that it started to blur the lines between talking about the phone's browser and talking about a Phonegap app.

What is unclear to me is if an app on Android using Phonegap uses the same cache as the phone's built in browser. Is Phonegap essentially an extension of the existing browser facility, or is it it's own separate stand-alone and self contained browser?

Critically, if a user clears the cache in their browser, will that impact an installed app based on Phonegap?

Answer 1

Since Phonegap uses Webiview to render your app : WebView and Phonegap.

And For security reason each app that uses WebView has its own cache and history. "No User or OS wants such data to be accessed by 3rd party applications". So in a nutshell, your app will keep its own history and data in its cache folder and will be deleted in one of the following cases:

• User manually deleted them.
• User used app setting screen and deleted them.
• App uninstalled.
