Android: Accessing images from assets/drawable folders
android, assets, drawable, image
Solution
I don't think so there is bit difference in performance of using these two folders, I think using drawable folder you can get easily images (All will be indexed in the R file, which makes it much faster (and much easier!) to load them.), and If you want to use it from asset then you have to use `AssetManager` then using `AssetFileDescriptor` you have to get those images.
`Assets` can also be organized into a folder hierarchy, which is not supported by resources. It's a different way of managing data. Although resources cover most of the cases, assets have their occasional use.
In the `res/drawable` directory each file is given a pre-compiled ID which can be accessed easily through R.id.[res id]. This is useful to quickly and easily access images, sounds, icons...
Problem
The app I am currently working on has hundreds of images. At the moment I store them in the 'Drawable' folder. I was thinking about moving all of them to Assets folder. My question is: Is there any difference in performance when using both approaches?
