How to make an application responsive in kivy ?

[mahmud al hasan]

I am building an application which will run on different devices and have to be responsive. 

Is there any easy way to make this app responsive?

make sure that you are using metrics and not making your widgets inside python.

You can use multiple threads for the app

I have also tried to use threading.

I tried to display a gif image while creating a large number of widgets.

But the gif freezes.

Avoid loading widgets more than once, and think of ways to have as few widgets as possible.

I had a carousel with over 30 items and it took over 5 seconds to load the 30 widgets.

To make it snappy, I made it so the carousel could only have 3 slides and loop infinitely. Every time you swipe the carousel, the left and right slides load with new data. Now it's incredibly fast, even if there are 300 items.

Thanx for your answer!

I 've done somthing similar and there are no annoying hangs. But I'd like my loading gifs to animate properly.

If you want your .gif files to load without freezing then you should extract each picture of the .gif into a folder. You can automate the process using gimp and by adding the gimpfu plugin to export each picture into a folder

Thank you for your answer! 

The gif is loaded quickly, but stops animating, while other widgets are created. When the creation of these widgets is finished, the gif continues to animate.

To prevent this you can load the animation in the mainthread while creating the widget in a different thread this will not interfere with the process of the mainthread making the .gif to load simultaneously with creation of the widgets
