i have problem, when load image, image is die. How check image is die.
thank
If you are trying to load images from the internet and place them inside a view, but they are crashing you could use Picasso. Picasso will let you load images from the internet, and if no image is present you can use a placeholder image instead. Picasso wont crash if you have a placeholder and a null image from the internet.

I need to display a list of images in my application, and i get those images from an API call as an URL. Now I'm using Glide to show them, but i don't like the loading effect it makes (blank space while loading, and the the image). Is there any way to instant show those images, without any loading time and possibly without downloading them?
Since the images are stored on a remote server there is no way to bypass the downloading process, however Glide makes sure to only download the image from remote server when necessary, as the docs state
By default, Glide checks multiple layers of caches before starting a
new request for an image:
Active resources - Is this image displayed in another View right now?
Memory cache - Was this image recently loaded and still in memory?
Resource - Has this image been decoded, transformed, and written to
the disk cache before? Data - Was the data this image was obtained
from written to the disk cache before? The first two steps check to
see if the resource is in memory and if so, return the image
immediately. The second two steps check to see if the image is on disk
and return quickly, but asynchronously.
If all four steps fail to find the image, then Glide will go back to
the original source to retrieve the data (the original File, Uri, Url
etc).
To resolve this,
but i don't like the loading effect it makes (blank space while
loading, and the the image)
You can instead add a default placeholder on the ImageView until the real image is downloaded. This will display a default image while your actual image is downloading and then after download completion will replace it with the actual one.
Glide
.with(context)
.load(url)
.placeholder(R.drawable.ic_placeholder) //your default placeholder resource
.into(imageView)
you can display images from url by two ways:
Without any third party library:
URL url = new URL("URL of image here");
Bitmap bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
imageView.setImageBitmap(bitmap);
Second way is by using Picasso
I am working on an application that has this image gallery activity where images are loaded from disk using Glide. These images are downloaded separately through DownloadManager. The problem is that these images might not have been downloaded by the time the user opens the gallery. I guess one way would be to load these images dynamically once each file gets downloaded by going through a BroadcastReceiver but I am wondering if there is an easier solution? Some of the images only shows parts of itself while others don't show at all, and in order to view the full images I have to navigate back into the gallery so that Glide can redo the loading. I would instead like the images to be displayed once they are able to load. I also tried using a placeholder but it will never be replaced by the image (I would also like to avoid using a placeholder image since I don't have any). The images are displayed in a GridView and loaded in getView method of a BaseAdapter. (Currently I also have to avoid storing the images in cache otherwise the incomplete images will be shown the next time as well). Code:
val file = File(urls[position].toString())
Glide.with(context)
.asBitmap()
.load(file)
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.fitCenter()
.apply(RequestOptions())
.into(imageView)
I am new in android app developing and got stuck in this problem. To understand my problem -
Let, I am a developer and I have an app. The app has a imageview. In that imageview, the image will be loaded using glide load(url) method from my(developer) website. Now I(developer) want to change the image that will be shown in the app same imageview. But if I change the image the image url will be changed and glide load(url) method will not be able to download new image? How can I solve this problem or what topic should learn to handle this issue or what is the alternative?
Download image
Save to disk (optional)
Modify image (optional)
Show modified image in ImageView.
(You don't need glide here)
How to load images in same image view from web or local android gallery?
I have an image view which has three options for loading images templates from web service,from gallery, from camera.I am using Glide library to load images from web service, Now, if i load image from web by glide and remove that image by remove button which i have for removing a picture after i pick image from gallery it doesn't load the image from gallery instead load the same image from glide which i removed before.
write the code like this for loading image .
Glide.with(mContext).load(imgUrl)
.thumbnail(0.5f)
.crossFade()
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(imageView);
Glide Library Intoduction Go through with this link, hope it will be work
You can use Picasso library. Image loading using Picasso is very easy, you can do it like this way
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
and in their website you can get every details.
and another Library is Glide. You can use Glide too for loading image..
You can also use Glide:
Glide.with(context).load(image).asBitmap().placeholder(R.drawable.placeholder).error(R.drawable.error).into(imageview);
I am parsing a json schema which contains textual info and image urls for my android app. I want to read all the images from the schema and then show them in the gallery view of my android app.
But the problem is, the image urls contain HD pics and it takes a lot of time to load. Is there a way I can reduce the size of those images at run time and then display or can you suggest any improvement tip so that the images could load quickly from the schema?
Thanks
Try using Picasso library, it can resize your images whatever you like and bind it to ImageView. See also my answer here.
But if your images on your server are too big, it all depends on your internet connection, how fast they get to your device.
You can resize your image downloaded from url using picasso library. Also it will allow lazy loading of images and you can also set placeholder and error images in your imageview.
You can read complete documentation here: http://square.github.io/picasso/
Picasso.with(context)
.load(url)
.resize(50, 50)// resizing images
.centerCrop()
.into(imageView)
