Currently my android application shows a black screen with a loading wheel as it processes the user's request i:e as it gets content from the server. I would like to modify this screen to include an icon (image) that fades in and out continuously instead of the loading wheel. Is there any possible way to do it?
Yes, you'll use an Alpha Animation
See here
and here
and lastly here for a good tutorial on Animations with some nice code.
In order to "chain" your animations so that one starts after the other you'll use an Animation listener and start the other one from the onAnimationEnd method callback. Don't forget to put an if statement in there that checks to see if your stuff is done loading otherwise you'll end up with infinite recursion of your fade in and fade out.

How do I add some simple sliding down animation to card view every time the fragment is opened/accessed? I only get to see animations when interacted but not those automatic animations...
do I only need to like copy paste codes of those scripts that trigger animation when a certain interaction is executed to my fragments?(sorry for the English... this might also be the answer on my question but I still want to listen to those who know how..)
So im making a android app in Unity an im trying to make a specific timer so the timer starts as soon as you go the the scene and also I want the numbers to scroll down then stop for a second then scroll again it would look something like this
5
6
00:14:57
8
9
and it would scroll down to the next number ten stop then the next number then stop
how to make a timer in unity with this behavior and look ?
There are plenity of ways to make a timer, I'm going to assume that that's not the trouble, what you are asking for is an animation that looks nice and works with the data of your timer.
You can have a FSM in the animator to make an animation between three text components so each second them will scroll up, once the upper text is outside the view, ui mask, you put them at the end and then change his text value to the next second and so on in a loop.
Another way to do this is the same I just wrote but using scripting and coroutines instead of the animator, I prefer this approaching since I have full control of what are appearing to the user and what are occurring behind in the code.
The main activity is a login page. I have included a splash screen as well. What I want is to apply animation to the splash screen. For that, I am trying to put it in a separate fragment. How can I do this?
I have created a theme and everything that is needed to implement a basic splash screen.
Most of the apps(youtube, facebook etc) don't have an animated splash screen because, all the code initialization drops a lot of frames in your app. These frame drops will be clearly visible if you try to animate the screen.
For your animations to be smooth, a frame has to be drawn every 16ms. Even if one frame is not drawn, users can see the change... what this means is, if you are jumping a ball on ur splash screens.. the easing function you apply to the animation will not work as expected.
Solution:
In your launcher activity, just have a simple ui. As minimal as possible. This will give the user a feeling that app launched quickly. Once your initializations are over, you can attach your fragment which can have the same UI as activity and then make any transition.
In practice:
Launch activity A(launcher) -> UI can be a simple white screen with your logo in the center of the screen.
Once your initialization(all the libraries that load in your Application class like firebase, ORM, analytics tools ect) is over, attach your fragment with a screen containing the same white screen and logo.
This way the user will not know transition from activity to ur fragment as the UI is same. Now you can do any kind of animation in your screen. The initialization time varies from application to application and phone to phone.
Sometimes you see in android applications that the move the button from one side of the screen to another (cosmetic stuffs) and it looks nice. Kind of like powerpoint presentation when you slide in text.
I was wondering, are these done typically using Animations in android classes or is it moved using coordinates/draw function in a loop. I am not sure which way is typically this done.
Thank you
I am not sure what exactly you mean (maybe you can give a specific example/app), but usually you use the Animation class to create an animation. There are some specific animations (subclasses) that can be used, but you can also create your own (by subclassing or via xml).
The one you describe sounds like the TranslateAnimation, that just translates the coordinates of a view at the beginning of an animation to coordinates at the end of the animation.
Also take a look here, for further reference.

What I want to achieve is a flip animation when going from activity to activity.
I've seen a recommendation somewhere on SO, that I should use appropriate layout animation in one activity, switch to next one without any animation whatsoever and then execute the second half of the animation in the second activity.
I guess it could work, not tried it yet. But what bothers me is more general aspect - I believe it should be possible to achieve the same effect with activity transition animation, but...
Somewhere (I guess it was SO, but I can't find it now) I've read that during the activity transition animation the background should always be fully covered by the animated activities. I'm not sure why - I can see the background is always black on all my devices, and making it visible during the animation appears to be harmless.
But perhaps it is not guaranteed? Can someone confirm that requirement? Is it officially stated anywhere?
