Blank image (no image) is shown after couple days.

Thanks for this awesome library.
I have used it in one of the product for my client and initially it works fine, I preload the images and they are shown even offline.

But after a few days (some random time I guess), it shows blank image. Please see this video:

Let me know if this is a known issue or if this can be fixed.

Could you try/answer the following:

is the library writing any logs?

which caching period did you set?

did you try it on an actual phone? Sometimes the Simulator makes issues due to switching internal app ids.

did you reinstall the app?

Thanks for checking into this.

I did not set any caching period, so I believe the default should be 3 days. Also after 3 days if cache is deleted, the image should download the image back from server which it does not even when internet is available. Also when this condition happens not even fallback image is shown.

The video I sent is from the real device, it happened in iPhone and Android both, also I couldn't get the chance to get the logs.

Also when we re-install the app and installs again, the problem is gone because the app content is deleted and refetched from the server.

Can you check if the problem still exists in V0.1.9?

Thank you!

I have encountered this problem before, and i did this:

1. don't call restore continuously, just call it once in app init.
2. If the app is offline, the expired image will still be deleted. I added a parameter to prevent this from happening. (iamiota@7f5334a)

Hi @BHesseldieck,

We are facing the same problem on iOS devices. Do you have any idea, the way we can fix it ? or next release date ? :)

It's central for us as we develop a picture based communication app for people with disabilities...
