NetWorkImageView or Volley not updating shown Image
I'm trying to get the refreshed Image from my Web-Server after I uploaded a new Image to it. I set the cache-control in the header to must-revalidate and max-age=0. However, the Image remains the same Image until I close and open my app again.
The Image is served via a Node.js Server with Expressed on a url that always remains the same, but the ETag changes when a new Image is found and the Cache-Control policy is set to "max-age=0, Must-revalidate". In the App I call NetworkImageView.setImageUrl() again, but the Image remains the old apparently cached one.
Im updating the Image like this.
NetworkImageView niv = fragmentManager.findFragmentByTag("currentFragment").getView().findViewById(R.id.niv_pic);
niv.setErrorImageResId(R.drawable.ic_launcher_foreground);
niv.setImageUrl(Constants.API_URL + "/user/getImage/" + user.getId(), NetworkSingleton.getInstance(this).getImageLoader());
In addition i tried invalidating the cache:
NetworkSingleton.getInstance(context).invalidateImageCache(Constants.API_URL + "/user/getImage/" + UserSingleton.getInstance().getUser().getId());
all this does is basically call
cache.remove(url);
on an androidx.collection.LruCache
What I would expect is for the NetworkImageView to update the shown Image when I call the setImageUrl, but it really does nothing at all. Only when I quit the app and open it again the picture updates. I'm really out of hope here, but I hope you guys know a solution for this.
