Just a quick question as I'm facing an issue here:

What's the best way, in terms of performances and speed, to populate a ViewPager from a list of URL stored on Firebase,using Glide ??

I mean, should I pass an array containing the URLs to the ViewPager Constructor? Get those URL from Firebase directly on the FragmentPagerAdapter class?

Cheers

    Yes. Glide is even recommended by Google. Based on your needs you can switch between Glide and Fresco. Two of the best image loading libraries in my opinion – rohitanand Feb 16 '17 at 06:24

  • in my Android-FirebaseApp I rely on Picasso, http://square.github.io/picasso/ – Khaledonia Feb 16 '17 at 08:08
  • @Alexander I've also used Picasso. But then I discovered Glide. It has better performance because of it's image compression algorithm. You should give it a try – Rosário Pereira Fernandes Feb 16 '17 at 08:35
  • @RosárioPereiraFernandes may I ask how are allowing your users to upload their graphic data? In my application I convert their data to the desired bitmap quality and then upload it. Picasso has been cordial to the users all the way so far. – Khaledonia Feb 16 '17 at 08:38
  • Same thing I do – Rosário Pereira Fernandes Feb 16 '17 at 08:42
  • Thanks guys for the comments. However, my issue is not whether or not using Glide (which I Love and use very often) but it's about when/where loading the Images URLs. What is the best and most efficient/quick way in terms of "architecture" – Andy Strife Feb 16 '17 at 19:05

Ok so after multiple tries and testing, here is what I have found to be the quickest:

Load all the URLs into a String Array and pass it to the ViewPager Constructor.

If you load the URLs on the fly directly from the ViewPager Class, it is slower.

I hope this will help others in the Future

  • Can I get the URLs from knowing just the appsot URL? Because, if I add some images on Firebase, I need not change the Studio code all over again. – Sumukh Bhandarkar Jul 22 '19 at 10:07
