I am having problem in rendering data in my react native app.I need help. Actually there is a listing of around 3000 activities which i want to show in my app.The listing includes cards of different sizes depending on the content.I am currently using flatlist to render this dynamic content but the performance is very slow and blanks space appears after some scrolling as i scroll the listing down it gets slower. I have used the Recycler view as well but as my content cards are of dynamic sizes and recyler view limits from dynamic sizes.I really need help from experts and open to any suggestions.Thanks in advance.
I think this article would be a good starting point, it solved a lot of issues for me.

I have a react native application that needs to display the same info from the server almost in real time when there is a change. How I'm doing it now: I created a setInterval() with a fetch inside that runs every 10 seconds. The problem is that sometimes there is no change in the server for hours and the app keep asking the serve for info that its already there creating a lot of unnecessary traffic.
Is there any way to do the other way around? Like, the serve asks the react native app to check for updates? What would be a better solution?

I have to make a website that will render multiple images at once like a shirt which will have multiple parts like a collar, sleeves, etc. I have to combine all these images at once and show the image of the whole shirt.
How could I do this as fast as possible to give the user a better experience?
I recommend you to use a npm module called sharp. By using that, you can resize your image to smaller, which will make your image loaded faster. Besides, you can serve dynamic image based on client device resolution, and that could obviously decrease the time image loaded.
sharp website: https://github.com/lovell/sharp
just you can load images from low quality to high quality using progressive jpeg-https://www.hostinger.in/tutorials/website/improving-website-performance-using-progressive-jpeg-images
if you want load your images faster you can do image optimization:

I was looking at the Soundlcoud Widget docs
http://developers.soundcloud.com/docs/widget#
I noticed there is a parameter for 'download'. I tried it on the HTML5 sharing widget it didn't turn on the download link. Is there a way to show the Download link?
Example
http://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F46911134&auto_play=false&show_artwork=true&color=ff7700&download=true&sharing=false
Thanks
This is actually the intended behaviour. A lot of the time, the widget is displayed in a relatively small frame, and showing all the buttons creates too much visual clutter. A redesign (to use icons, for example) is coming, but I can't give you a date on when that will be ready. In the meantime, the documentation will be updated.

What tricks can I do to make my app feel "snappier"?
For example, when I click on a menu button, which loads a different nib file, there is this 1 second delay before the new view shows up, making it feel like the app isn't responsive.
Thank you,
Tee
You could reduce the nib load time by simplifying the content or making some of it load after the view controller appears on-screen.
You can run Instruments on it to try and get an idea of where the choke point is. If it feels unresponsive, compared to other apps, then maybe you're doing something wrong or computationally expensive.
Check that your images are sized correctly. If they're too big that'll up the load time + memory usage.

In SAP,
can we have a push button on custom container in ALV. Is it possible or is there any other possibilities for that.? Pls help me...
Thanks in advance
Well, I would rather use custom containers for things like tableviews. If you are working with the standard Dynpros you can just add a button in the dynpro designer and implement the behaviour you would like. To give a more detailled answer, I would need to know what you are planning to do. Of course you can also create a ALV grid and modify the buttons which are displayed there. Maybe you elaborate a little bit more what you're planning to do and then I can give you a recommendation.
Yes, this is possible - check out class CL_GUI_TOOLBAR and the associated documentation (like http://help.sap.com/printdocu/core/Print46c/de/data/pdf/BCCITOOLBAR/BCCITOOLBAR.pdf) and sample programs. AFAIR there's a demo program that lets you assemble a toolbar dynamically, I just don't remember the name. You'll usually want to insert some kind of splitter first, then add the toolbar to one side of the container so that you can place other elements like trees or tables next to it.
