View Full Version : How to persist models with an image in Byte[] or Drawable format?

5 Mar 2012, 5:25 AM
Hello everyone,

I would like to persist objects with images in my app. Normally I would use the localStorage, but since this can only save Strings, I got a problem.

My first idea would be, to encode each image into a Base64 String and when I load them from the localStorage I would decode them back to Byte[] format.

What do you think about this solution or do you have any other plan/tip/idea?

Thanks in advance!

Base64 is the way to go if you want to save to localstorage.

Thanks for the fast reply.

But your post makes me curious, which other ways of persisting do I have or would you recommend when working with JSONs?

By the way, one more question which is a bit off-topic:
When I want to use an offline mode in my app (when no internet connection is available, the app should use the localstorage) and you want to just save/persist the username and password in the app, how would you do it? a Store using the localstorage with two strings? (one for username and one for password)

Very big thanks in advance,

Ok, got it, sry for being so blind.

Just one more thing:
Since the localStorage doenst seem to be the best choice for JSON-objects, what about using Phonegap with SQLite?
