Glide not updating image android of same url?

Solution 1:

//Use bellow code, it work for me.Set skip Memory Cache to true. it will load the image every time.

 Glide.with(Activity.this)
.load(theImagePath)
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.into(myImageViewPhoto);

Solution 2:

Glide 4.x

Glide.with(context)
     .load(imageUrl)
     .apply(RequestOptions.skipMemoryCacheOf(true))
     .apply(RequestOptions.diskCacheStrategyOf(DiskCacheStrategy.NONE))
     .into(imageView);

Glide 3.x

Glide.with(context)
     .load(imageUrl)
     .skipMemoryCache(true)
     .diskCacheStrategy(DiskCacheStrategy.NONE)
     .into(imageView);

Solution 3:

TL;DR.

1. you can skip caching by adding the following lines:

   Glide.with(context)
           // ... (your usual stuff)
           // then this
           .diskCacheStrategy(DiskCacheStrategy.NONE)
           .skipMemoryCache(true)
           .signature(new StringSignature(String.valueOf(System.currentTimeMillis())));
   

2. OR : you can workaround caching by adding a dummy random argument to your URL:

   Glide.with(context)
           .load(url + "?rand=" + (new Random().nextInt()))
           .into(imageView);
   

What's happening?

When your picture is loaded the first time, it's stored locally in what's called a cached memory (or simply "a cache"). When you request it for a second time Glide fetches if from the cache as if it was a successful request. This is meant for many good reasons such as: offloading your server, saving your users some data and responding quickly (offering your users a smooth experience).

What to do?

Now, concerning your issue: you need to disable the cache in order to force Glide to fetch your image remotely every time you ask for it. You can do the following:

Glide.with(context)
         .load(url)
         .diskCacheStrategy(DiskCacheStrategy.NONE)
         .skipMemoryCache(true)
         .signature(imageVersion) // supposing that each new image has its own version number
         .into(imageView);

Or, in the case where you can't know when a picture is changes (no imageVersion), use a unique signature for each picture.

Glide.with(context)
         .load(url)
         .signature(new StringSignature(String.valueOf(System.currentTimeMillis())))
         .into(imageView);

Another clean way would be to configure your picture's cache strategy in your server and use .diskCacheStrategy(DiskCacheStrategy.SOURCE).

A hacky trick worth mentioning

If adding a dummy GET paramter to your target URL doesn't break anything, then you could simply workaround caching by passing a random argument each time you fetch the image, this will push Glide to think you're querying a new endpoint, thus, it won't check the cache.

Glide.with(context)
         .load(url + "?rand=" + (new Random().nextInt())) // "&rand=" if your url already has some GET params
         .into(imageView);
