Thanks

@bathejasumeet I also had this problem. I had a GridView displaying 16-30 images (before scrolling down), and they were all 600x600 images. I kept getting the memory issue. I changed the gridview to display images that are 100x100, and that improved things greatly. But, the images dont look crisp anymore.

This might be causing the issue:

In contrast, when using ImageSource or Base64 encoded string, the Bitmap is transferred to Javascript, so it will be released when Javascript object reclaims. Javascript garbage collection happens less frequently than Java garbage collection which might lead to Out Of Memory.

Maybe you could expose garbage collection and call it with gc() whenever it is needed.
I would not know how you should expose javascript garbage collection in ios though.

@hettiger Is this what you're referring to? https://docs.nativescript.org/angular/performance-optimizations/images-optimisations

The optimizations here are all about the <Image> tag which we're not using with this plugin. I was getting out of memory error with 50 images (all same, 65KB each for testing) but even after installing the plugin I'm still getting the error. I thought fresco was supposed to take care of clearing memory and optimization stuff.

@VeeK727 I just wanted to add some information that I've had found in this article and thought it might be related with the issue described here.

Out of Memory Issue - 6000 items

Hi, I need to be able to show in a radlistview 7000 elements with cached images in an optimal way. Currently the url of the image is 400x300 / imagen.jpg. But when you go displaying products in the view it becomes corrupted. Someone could help me?

Thanks!
