What should I do to make my app run smoother?

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);

How to load one image at a time?

I have a form with 10 images which need to be downloaded from my server. The problem I have is that when the form is displayed, the library I'm using will start downloading all 10 images at the same time causing some of the image download requests to time out. (I don't know why it does)
So I think I could fix this by changing my code to download one image at a time.
Is my understanding correct in that I should treat each of the image download request as an Async task and chain them together so that only one image download request will be processed at a time?
Any libraries I should look into to save time in implementing this? Or any other techniques I should be aware of?

This answer is from the comments I had to this question.
You can use an AsyncTask.
You can update the ui when each has finished in the functions:
onPostExecute()
onPreExecute()
onProgressUpdate()

you can try Image loading lib Glide. You can set priorities for image loading so this can be achieved using Glide.

android slideshow from url

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.

How to load images faster, smoother, and without OutOfMenory error?

i am trying to write a media player application. In this i have to load album art(s) from a network to GridView of android. With my initial implementation, it's working fine, but it's not fast, not smooth. Loading images(.jpeg) taking more time. I have resize the images to low resolution, even now not working. In my observation, Saavn(android application) loading album arts very fastly.
How can i load my album arts with that speed in more efficient way.
I have gone through http://www.coderzheaven.com/tag/faster-loading-images-in-gridviews-or-listviews-in-android-using-menory-caching/
but not helpful. Any other ideas?

Have you thought to use Image loading libraries?
Try to use Universal Image loader library, its good.

Try this image loading library.
Picasso
Sample code is availabe Here
Easy to integrate.

Image loading with JSON service

I have an app where people can set pictures as wallpaper but its really slow because pictures are very big. This app load pictures and then when i want to see it again it has to load again.
What to do to make it faster? I use Json service. My pictures are from server. i am using universal image loader.

Theres 2 types of cache in android, the memory cache and the disk cache. You should use picasso its a library that implement both and is very easy to use (1 line of code).
