Question

Just started with Android, and I have a question about handling images.

I’m thinking of creating a simple quiz app with images as well for each question. Let say if it is 100 questions, I need to have 100 images, one for each. Where would you add the images, and how would you retrieve them for each question?

Answer 1

There a quite a few things you could do:

1. Add all the images to res/drawable. This will however, depending on the size of the images cause your APK-file to increase in size and it’s not very flexible should you want to add/remove questions at a later point.
2. If you have a webservice at your disposal, from which you could download the images, you could download the images to a specific folder on the device and load them into the app from there. This would also make the app more versatile when removing/adding questions.
3. Same as nr. 2 – but you save the images in a database on the device.

Number 1 is probably the easiest to use – but will require an update of the app whenever you add/remove questions.

Number 2/3 would be preferable in my opinion, but would also require that you have the needed webservice availible for use.
