I have created image app in android studio. There are almost 75 images in drawable resources in android studio.
But as the image size is big, the app crashes or images scroll very slow.
To loading the image in application use Glide Image loading library
Glide
It will load image asynchronously and efficient way
After if problem persist review ur code and check in android profiler
This sample way how to load images in image view and for example on Glide search in google
GlideApp.with(this).load("url").into(imageView);

I want to make a simple gallery app on Android (like Google Photo or any standard gallery app). I've read that the best way to load images is use Glide library (Google recommends to use it). But how can I load multiple images (from sdcard) using Glide? I can use Glide.with(ctx).load(File file)... for loading single image, but I dont know how to load multiple. And what library does Google Photo uses (it works really great both with local and with cloud images)?
So, the only one way to load images with Glide is to load them one by one using Glide.with(ctx).load(File file)...
But it's not a problem to use it even if we have a lot of images - it works perfectly. And it seems that Google Photo app for Android uses Glide, that's why Google recommend using it.
I need to make a horizontal slideshow of images from a URL. I've been searching about and have only found examples with ViewPager showing images from the drawable directory.
There are so many image-load libraries that I don't know what is appropriate for my project, if Picasso or universal image loader or volley...
I tried a universal image loader but seemed very slow actually loading images.
What I need is to get exactly what this application does, which includes a counter images.
Here is the link.
You can try picasso. I used it on this app that I published a couple of days ago.
https://play.google.com/store/apps/details?id=com.jattcode.mikimedia. Is this what you meant. There's an image slider activity if an ad has more than 1 image.
For example, when I created an app in android.
I included a image file in the app. When I added the image, the app's
file size increased exactly as image size.
But my question is, many apps in google play apps includes so much images but
why do they have so small amount of file size?
Is it that they don't use picture format and using drawing api like canvas?
Because there these images are not being stored in app memory, In runtime they are downloading the images and displaying in the application. So There application size is not that much big.
But in your application you are storing images in drawable folder that is why your app size is getting increased upto as much image size is.
Most of them create a hidden file in storage... And then load their images from their... Some developers also load image only in run-time. Suppose you have a webview behind a Layout. That WebView is only for loading a image. If you set OnClickListener on this Layout then it behaves like a image button. its a silly example :P
The best practice is to use Glide or Picasso to load image from server to your imageview.

In my Android application I have to fetch some images from the server and show them.Same image is shown in some of the pages.Now I am downloading the same image in each page and getting out of memory error.How can I reuse the one that I have downloaded earlier in each page
Use Android Query, and then Image Loading in particular. It's really easy and performs well.
I am trying to load images from the server and want to know how can i convert the images into the thumbnails so that they get uploaded fast and how can i get the larger images from the thumbnails fast . I have tried many things.
Thanks in advance
At the server you need to keep 2 copies of an image. First is the thumbnail and the other one is the image.
First you need to download the thumbnail asynchronously. And if the user wishes to see it then download the original image asynchronously. While downloading original image you can show the scaled thumbnail image as the placeholder image. So when the downloading is completed show the downloaded image.
Make sure to download the images asynchronously otherwise you will block the main thread and UI will get stuck.
This is how google images work.
In iOS there is a very nice API SWPhotoBrowser which handles the downloading and caching of photos from the web seamlessly. I am sure there must be some API for Android as well.
If you need any help I can help with the code as well.
For Android you can use ImageLoader to download and display image - it can use cache and save memory while loading scaled images.
