android replace drawable image programmatically

Question

I have 10 images in drawable directory in my android project and I'm using those images in a gallery. I want to replace those 10 images programatically upon user request to download new images from the web.

Is this possible to replace the images in drawable of my App with downloaded images?

Thanks in advance

You can keep the files in the internal storage eg:- `files folder` if you want images to be replaced. — Lalit Poptani, Sep 06 '12 at 04:44

This is not possible. You will have to download and store it on disk. Either in internal memory or External memory.

No, this is impossible act. You cant manipulate any resource of APK(read-only).

You can store your image either in your Phone memory(Internal or External) or You can just create a Drawable(cache) at Runtime and flushed it.

You having directory called /data/data/package_name this folder will gets delete once you uninstall your Application and for other directory you have to delete manually.

You can not change resources of your App programmatically(as @hotveryspicy says),but you can create specific directory for your App(either private directory for your App or public) and download images to it.When your App wants to show images it has to check if there exists images in that directoy,display images from it,else display images from it's resources.
