In my Android application I want to have a Floating Action Button to display a success state. I would like to have something like in the picture below:
But I have no idea how to animate the cross to the mark. Can someone please explain to me how I can do that? Is there maybe a library or something like that? Atm I'm using the default FAB from the design library.
This question got me interested in checking out AnimatedVectorDrawable, so I went ahead and made a small sample app that will achieve a similar animation, on github here.
Bad quality gif here.
Couple things to note: minimum SDK is set to 23 to make use of AnimationCallbacks for starting the 2nd animation, but you can achieve the same result using a Handler.postDelayed() with your animation durations to handle the drawable change and animation start. Since AnimatedDrawableCompat does not support path morphing, I needed two drawables to get the two different images.
Should be compatible with the Support Library AnimatedVectorDrawableCompat if you choose to use it as well.

I am investigating if there is a 15+ API to implement sidebar icon transitions as displayed on the video by google:

If I use the classic ObjectAnimator.fromFloat() the code will be huge and cumbersome.
Is there a way to reposition the items with a reasonable length of code?
Use the following library with sample.

You will get the perfect result as you want
All across the internet and several Stack Overflow pages, there are detailed instructions for the implementation of Floating Action Buttons, but nobody explains where I might be able to acquire the icon myself. Is everyone creating his own action buttons for his UI, or is there a downloadable library somewhere I have yet to discover?
Please link and explain!
Google doesn't provide any code for it, but it should be pretty basic to build yourself.
If you'd prefer to use a library for it, I use this one by shamanland: floating-action-button. You can change the color and icon displayed, and have it auto-hide when the user is scrolling.
There's another popular library by futuresimple here: android-floating-action-button. It includes support for sub-actions with text labels, and two button sizes, but won't give you auto-hiding on scrolling. I think I started with this one and switched to shamanland's, but I don't remember why.
I am creating Floating Action Button and shadow with .xml files as explained here and using icons from icons8.com, it has Android Lollipop specific icons.
I'm updating an app to have a more material design look and feel. I have a refresh icon in my toolbar, and I'm wondering if this icon should change. Looking at google's new icons here https://github.com/google/material-design-icons/blob/master/navigation/drawable-hdpi/ic_refresh_grey600_36dp.png , it looks like it has changed.
But on their downloads page it has a different icon https://developer.android.com/design/downloads/index.html. This is the one I have been using and it has two arrows. The new one just has one arrow.
Does anyone know if the one with one arrow is indeed the one google is switching to with material design?
you are downloading the wrong resources, you are still downloading the HOLO resources. You want the material resources found here

I was wondering about the exact same thing some few days back. I couldn't find a definite answer anywhere, but from what I could gather, the one that is posted here, this is the latest one. If you see the latest Gmail android app, the refresh icon that comes up when you pull down, is the one with a single arrow. (and not 2 arrows)
Path is a social networking application that allows you to create a small social group to be intimate with rather than a large one like Facebook.
Something that really impresses me about this app is the UI. They have a signature menu button, which is a circle that spins releasing smaller circles as menu options.
I love the way it look and want to know how to do menu/UI animations in general. Could anyone direct me to sucha tutorial/article?
Thanks.
Here is the Path app: Path
Here is some app that just has the menu animation (no source, unfortunately): Path UI anim demo

Looks like they are just using a some custom made drawables for their button backgrounds and tweened position and rotation animations. Please see this resource for information on Android UI animations:
Android UI Animations
I'm starting out with Android development, and I'm kind of stuck. Basically, I have a layout with dynamically added ImageViews, and I want to have the ImageViews change their image every once in a while. However, I'd like to add some sort of transition or changing animation, like a flip or a flash.
I don't really know where to even start to look for an answer to this question. Any help is greatly appreciated.
The android framework has this totally covered:
http://developer.android.com/guide/topics/graphics/view-animation.html
Basically, you are looking to define "tween" animations between your drawables (imageviews). After you define your animations you can even define a set of drawables to show one after the other using frame-animation.
Check out the following for all the gory details:
