I'm using Picasso in android app loading image from web url, But I see image is not updated when I updated image on web.
Picasso.with(context).load("http://testServer.com/Images/sponsor.png").into(imageView1);
Thanks in advance.
Picasso uses a cache mechanism, so the same image is not re-downloaded twice.
If you need to bypass this cache, you can change memory or network policy to do this.
Picasso has builtin caching so the image cached automaticly. try invalidating.
example:
Picasso.with(getActivity()).invalidate(file);
public void loadImage(ImageView imageView, String image_url,Contextcontext)
{
try
{
Picasso.with(context)
.load(image_url)
.memoryPolicy(MemoryPolicy.NO_CACHE)
.networkPolicy(NetworkPolicy.NO_CACHE)
.placeholder(R.drawable.default_image)
.into(imageView);
}
catch(Exception ex)
{
ex.toString();
}
}
try to download aquery library see here https://code.google.com/p/android-query/wiki/ImageLoading

I am developing A App which requires loading multiple images from their urls. I save all the images in firebase storage. I am currently using a compressor to reduce the size.
newImageFile=new File(uri1.getPath());
try {
compressedImageFile = new Compressor(ProductAdd.this)
.compressToBitmap(newImageFile);
} catch (IOException e) {
e.printStackTrace();
}
baos = new ByteArrayOutputStream();
compressedImageFile.compress(Bitmap.CompressFormat.JPEG, 100, baos);
thumbData1 = baos.toByteArray();
and I using Glide to load the image from the url
Glide.with(context).load(imgUrl).into(holder.cutImg);
I wanted to know if there is any way I could improve to load images much faster. Maybe store them in a specific format.
You can load a thumbnail of the original image into the ImageView before the original image loads.
Glide.with(fragment)
.load(url)
.thumbnail(0.05f)
.into(imageView);
This will load the 5% quality of the original image into the view and when the complete image loads it will be replaced.
And if you're having a separate URL for thumbnail then
Glide.with(fragment)
.load(url)
.thumbnail(
Glide.with(fragment)
.load(thumbnailUrl))
.into(imageView);
Now when image loads it will be immediately loaded into the view, here you can use the transition for a smooth effect.
Glide.with(fragment)
.load(url)
.thumbnail(0.05f)
.transition(DrawableTransitionOptions.withCrossFade())
.into(view);
You can checkout my project in which I'm also first compressing the Image and storing a thumnail image to Firebase Storage and then loading it.
You can also try different DiskCacheStrategies but I would suggest to go with the default one, it works just fine!
Here are various DiskCacheStrategies:
.diskCacheStrategy(DiskCacheStrategy.ALL)
.diskCacheStrategy(DiskCacheStrategy.NONE)
.diskCacheStrategy(DiskCacheStrategy.DATA)
.diskCacheStrategy(DiskCacheStrategy.AUTOMATIC)
.diskCacheStrategy(DiskCacheStrategy.RESOURCE)
You can use the disc strategy which will be used to store the image on the disc. So it may take time for loading at first but later it does not take time at all.
For Glide 4.x
Glide
.with(context)
.load(imgUrl)
.diskCacheStrategy(DiskCacheStrategy.DATA)
.into(holder.cutImg);
For Glide 3.x
Glide
.with(context)
.load(imgUrl)
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(holder.cutImg);
Please note: This will not refresh the image if you just update the image without updating URL. SO if you want to see the updated image you must update URL and Glide will automatically download an image for you.
if you are using firebase storage for host your images : Using FirebaseUI you can quickly and easily download, cache, and display images from Storage with Glide. source
Glide.with(context).load(model.imageUrl).thumbnail(0.05f).into(holder.imageView)
Is it possible to cache image using glide without showing it in the imageView?. If it is then how?.
Right now I'm doing this code:
Glide
.with(getApplicationContext())
.load("imageUrl")
.override(windowWidth(),(int)windowWidth()*0.5))
.diskCacheStrategy(DiskCacheStrategy.ALL);
But this is not working , when app is open glide load image not from cache but from url.
Since glide 4.X:
//to save img
RequestManager rm = Glide.with(context);
rm.load(imgUrl).submit();
//to load img
Glide.with(context)
.applyDefaultRequestOptions(
new RequestOptions().diskCacheStrategy(DiskCacheStrategy.ALL))
.load(imgUrl)
.into(view);
Based on this GitHub topic
i've never used it, but referring the documentation: have you tried the downloadOnly?
Glide's downloadOnly() API allows you to download the bytes of an image into the disk cache so that it will be available to be retrieved later.
https://github.com/bumptech/glide/wiki/Loading-and-Caching-on-Background-Threads#downloadonly
To preload remote images and ensure that the image is only downloaded once:
Glide.with(context)
.load(yourUrl)
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.preload();
Hi i am new beginner in android. I want to insert image in imageView from URL but whenever one time it is loaded from URL in imageView then second time it should be insert without internet means it would be stored in cache as well.
for this you can use picasso Library
You can download it from Picasso Library site simply put this jar file into libs folder. It will manage all property of Image.
http://square.github.io/picasso/
String imgURL = "Your URL";
ivmage = (ImageView) findViewById(R.id.imageView1);
Picasso.with(MainActivity.this).load(imgURL).into(ivmage);
You can use Picasso Library.
By Using Picasso, The Advantages are
Handling ImageView recycling and download cancelation in an adapter.
Complex image transformations with minimal memory use.
Automatic memory and disk caching.
To load Image from Url
Picasso.with(context).load(url).into(imageView);
Refer this link for Api : Picasso
you can use Glide https://github.com/bumptech/glide
Glide.with(this).load("imageURl").into(imageView);
I suggest picasso library for doing this. here is the detailed documentation of picasso library.
ex:
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
or you can make use of volley's ImageLoader. here you can find the documentation for Volley's image loading.
ex :
// Retrieves an image specified by the URL, displays it in the UI.
ImageRequest request = new ImageRequest(url,
new Response.Listener<Bitmap>() {
#Override
public void onResponse(Bitmap bitmap) {
mImageView.setImageBitmap(bitmap);
}
}, 0, 0, null,
new Response.ErrorListener() {
public void onErrorResponse(VolleyError error) {
mImageView.setImageResource(R.drawable.image_load_error);
}
});
// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(request);
if you are using volley. then you have to cache images manually. picasso will cache images by default.
So, I was starting my project and wants to use Picasso in my project because its popular and used by many projects out there.
I included picasso using gradle and tried loading facebook profile url with this. http://graph.facebook.com/rohitiskul/picture.
It worked very well. It loaded image from network without any issues. I restarted the app.(Without actually killing the process). It showed me the same image instantly cached in Memory.
But then, I killed the app (force stop) and restarted. It took almost 10+ seconds to load the image. And that image was loading from the disk when I checked in the debug logs.
My code looks like this -
In MainActivity-
Picasso.with(context)
.load("http://graph.facebook.com/rohitiskul/picture")
.into(imageView);
In application class-
Picasso picasso = new Picasso.Builder(this)
.indicatorsEnabled(true).loggingEnabled(true).build()
Picasso.setSingletonInstance(picasso);
Anyone with the similar problem? Any solution would be helpful.
I tried loading same Url with UniversalImageLoader and it was fast when fetching cached image from disk.
Edit
Earlier while playing with my app, I found out that Picasso wasn't loading the disk cached image when device was offline.
I encounter the same problem,
but find only slow for the first image, later images will be fast.
Probably it needs a warm-up (loading index cache) ?
Okay i got your problem. I have fixed it by doing this
Picasso.with(context)
.load("http://graph.facebook.com/rohitiskul/picture")
.networkPolicy(NetworkPolicy.OFFLINE)
.into(imageView, new Callback() {
#Override
public void onSuccess() { }
#Override
public void onError() {
// Try again online if cache failed
Picasso.with(context)
.load("http://graph.facebook.com/rohitiskul/picture")
.into(imageView);
}
});
Explanation:
Picasso will look for images in cache.
If it failed only then image will be downloaded over network. In your case from facebook.
This issue I had also faced earlier, with this what I understood that Picasso refer the cached image based on image name mentioned in the URL.
In your case you don't have image name in URL like 'image1.jpg'. Due to which Picasso is finding it difficult to read from cache and it downloads the image everytime
You can give a try to image containing the image name in URL and that will work
Picasso doesn't offer disk cache out of the box. Instead, it relies on an Http Cache.
Make sure you add OkHttp to your dependency list.
Add a string identifier with the stableKey method when making the request so Picasso can identify your requests and quickly load it from the cache.
Example:
Picasso.Builder(context).loggingEnabled(true).build()
.load(imageUrl)
.stableKey("myImage")
.into(imageView)
im using picasso library to load images.
However in my application, users can have profile pictures and the link for the image is constant... Picasso has no clue that the image has changed...
I tried using : .skipMemoryCache() but it wasn't an ideal solution...
Is there a way to check if there's a new picture in the same link using picasso? Thanks!
Apparently, there is no API in the current (2.3.2) version of Picasso to achieve this (but it is a work in progress - see this bug).
That aside, if you have control of the server side, you may want to think about your design decision to provide the changing profile picture at a constant URL.
An alternative would be: Include the current profile picture URL in the profile information you retrieve. This way, your cache can use the cached image - and as soon as the profile information provides a new URL, Picasso will fetch it. In all other cases, Picasso can leverage the cache.
I got the answer from this link
change your URL as shown below:
String imageurl = url + "?time=" + System.currentTimeMillis();
Picasso.with(getContext()).load(imageurl).into(imageView);
this worked for me. thanks
Picasso.with(context)
.load(url)
.memoryPolicy(MemoryPolicy.NO_CACHE)
.networkPolicy(NetworkPolicy.NO_CACHE)
.fit()
.placeholder(YOUR PLACE HOLDER RESOURCE)
.centerCrop()
.into(imageView);
One solution is to invalidate the cache like so
Picasso.with(context).invalidate(imagePath);
The other way to force download the image which then is cached for subsequent use as mentioned in the code.
Picasso.with(context)
.load(imagePath)
.networkPolicy(NetworkPolicy.NO_CACHE)
.into(userAvatar);
