Use case

Android system -- although very rarely -- sometimes kills the MainActivity after the image_picker finishes. When this happens, we lost the data selected from the image_picker. You can use retrieveLostData to retrieve the lost data in this situation.

In the current version, only one image can be saved to the local cache. But after multi-image support is merged we need to save a list of images to the local cache to retrieve them when it is necessary.

Proposal

We can deprecate the old cache and implement a new cache to save a list of images all the time.
