I am developing an app that will have a very similar interface to this , my question is, all that animation is from material design, but do i have to program all that stuff or android have anitmation libraries for material design that do that?
Some of the design stuff and animations are only available in android 5.0 and above only, like the FAB button and reveal effect.
2 options
Either write the code for animations and layout yourself for pre 5.0 devices
or
Use libraries that do the same thing like fab button and reveal effect etc
There are a lot of open source libraries that you can use in your project for e.g FAB button, arc animation etc.. to support devices before 5.0 Also then you don't forget to read there licence.
So, in short you will get small components from here and there like
reveal effect, arc animation, fab etc use them to achieve the effect.

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'm studying Material Theme and some things don't work in version lower than 21, like ripple effect, change the status bar color and primary text color, view elevation... even I using the v7 library.
For view elevation I tried ViewCompat.setElevation(view, value) and doesn't work. Anyone knows why and how I have to do?
For the ripple effect I tried to put the attribute android:background="?android:attr/selectableItemBackground" in the XML, but even doesn't work. I want a way of do it work in any version with just a code (without have to do separate codes for 21 version and pre 21 version). Is there a way of do this? Anyone knows how?
Thanks
The deal is that Material Design is a design language, a concept used by designers to prepare consistent UI/UX. It's not 100% implemented anywhere.
Android Lollipop has implementation of things which can be helpful in creating Material Design - compilant apps. These include shadows and ripples. Lollipop doesn't have high level Material Design things, like Floating Action Button, Snackbar, floating TextView labels and others. These are available as part of Design Support Library. You can create them by yourself as well.
Both shadows and ripples can be implemented on older Android versions to some extent. For example it's possible to create an animated ripple drawable, use it as a button's background and make it react to touch events. It's not possible to make it work smoothly, because that would require running the animation and rendering in a background thread which is available only on Lollipop and Marshmallow. Another examples are the circular reveal, the elevation system (not shadows, the drawing order) and truly rounded corners of CardView.
Colored/translucent status bar is an example of a thing which is totally reserved for Lollipop and Marshmallow, because it's a part of the system and cannot be backported at all. Another example is the new transition system.
Some things are not supported even on Lollipop. For example a floating EditText's selection toolbar. It's available only on Marshmallow. SVG graphics is not 100% supported on any Android version. Vector graphics on Lollipop and Marshmallow is a kind-of-an-SVG implementation with support for popular tags and settings. If you wish to have good vector graphics in your app, it's better to use a third party SVG reader and renderer.
ViewCompat and AppCompat make things compile. It doesn't mean that these things will work and look like on Lollipop. Design Support Library adds widgets, but most of them doesn't work like they should on Lollipop. For example CardView doesn't really cut corners, shadows are drawn with gradients, states aren't really animated. The two things you mentioned are implemented like this (pseudocode):
ViewCompat.setElevation(view, value){
if(Lollipop)
view.setElevation(value);
else
// do nothing
}
and
selectableItemBackground = Lollipop ? new RippleDrawable() : grayColor
There's a bunch of Material Design implementations scattered over github. Some of them implement only one thing, like RippleDrawable or FAB. Other libraries provide quite complete suport for widgets, shadows, etc.
Google is working on Design Support library adding more and more widgets. It doesn't have ripples or shadows yet though and probably won't have them due to performance and architectural difficulties.
I have my own library as well. I was fascinated by Material Design and frustrated by lack of implementation, so I started working on my own implementation of shadows, ripples, animations, widgets and other things. It's open source, free to use and you can find it here: https://github.com/ZieIony/Carbon
Edit: RippleDrawable
You need a RippleDrawable implementation. That should be easy as the source is open. My implementation is here: https://github.com/ZieIony/Carbon/blob/master/carbon/src/main/java/carbon/drawable/RippleDrawableFroyo.java
Then create an instance with your color and style. Set it as background.
Run RippleDrawable's animation in onTouchEvent of your view.
It's much more complicated to prepare a complete ripple with borderless mode, multiple ripples, layers, drawable states and all the stuff. If you wish, you can find all of those in Carbon (except multiple ripples). It's not only xml, but also overriden methods, extended widgets, layouts, attributes and styles.
There are simple implementations of ripples on github. If it's enough for you, you can just download a library and use it. For example this one: https://github.com/balysv/material-ripple
If you'd like to use ripples inflated from xml, it's possible as well. Check out this library: https://github.com/ozodrukh/RippleDrawable
I need to design a button shown in this image. On click of the green button shown in the image few options should pop up. Can any one help me in doing this in Android application.
Use FloatingActionButton from android design support library:
https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.html
You will need to include this dependency in your apps build.gradle file to reference it:
com.android.support:design:22.2.0
Here's a great reference:
http://antonioleiva.com/floating-action-button/
You could do it without the design support lib - which would be a slightly more difficult approach. I don't like the design lib approach because it adds some unnecessary permissions to Android Manifest via the manifest merger, and adds bunch of code I don't need (and I can change the compile API level to whatever I want).
So, basically - you would need a layout container (i.e. a RelativeLayout), and inside it you would put your main layout (a toolbar, list, buttons, etc). Then, alongside those items, you can put a simple ImageView to the bottom right, but spaced a bit from screen edges. Then you can make a 9-patch with shadow included for its background, AND for API21+ you can create a circle shape drawable, and add some elevation to it (this will generate a shadow).
If you want it to move, fade out, fade in, etc. you will need to do these things manually, which makes it advanced in comparison to the design lib approach.
I read a lot topics on Material design and sawed lot of example on it. Recently I installed a calendar application that called Today Calendar which have a Material design and Requires Android 4.1 and up, also the animations and transitions are all working on 4.1 and later.
The FAB's transition is very nice along with other views. I want to implement it in my application that requires API Level 14+, when the user clicks on the FAB it will transition to buttom with nice animation.
My design looks like this:
How to implement this transition?
I'm wondering about the different types of buttons available in android Lollipop. In Google's material design guidelines for buttons Google described the three different types of buttons available in API 21. The button, the flat button and the floating action button. I can't seem to find the documentation for the buttons (other than the regular). Does anyone know how to make use of the new button APIs?
Thanks,

There's no new API for the buttons. Material Design is a concept and can be realised using any API/framework (Android Gingerbread, HTML, Windows::Forms, etc.).
The flat button is a regular button with its elevation set to 0.
The floating action button is a regular button with its shape set to circle.
If you need a FloatingActionButton class or something like that, you should look for third party libraries.
