Backward compatibility Material Design - android

As Google says in this page, Material Theme is only available on Android L Developer Preview.
But how can these apps work on previous version of Android L?

There are other apps.
Do they use some components similar to material design?
Don't they use the "android:Theme.Material"?
Or is there a way to use Material Theme on previous versions (and I am the only one who doesn't know how to do this)?

I think they are using the components not the theme itself. If you try to give this theme as your overall theme in studio without the minSDK =21 it gives you an error. They are trying to emulate the material design.
For example if you want the floating action bar you can use this project. https://github.com/FaizMalkani/FloatingActionButton
I guess he uses frame layout to emulate that button on the lower right corner. Have a look!!

What is the difference between Android Material Design UI and Android UI without material design?

I am working on an android application. I am going to design User Interface and i have to use material design in it. I want to know what is the difference between Android Material Design UI and Android UI without material design ?
How should i use material design in my application.
You simply have to provide UI which fits the suggestions and rules from https://material.io/guidelines/
That resource does describe, for example, minimum sizes for UI elements, padding, margin, etc.
For the newest SDK versions of android most of these rules are already applied into default ui elements in Android Studio.
Material design is a comprehensive guide for visual, motion, and interaction design across platforms and devices. See The documentation
Material Design can be used in API Level 21 (Android 5.0) and newer or via the v7 appcompat library, which is used on virtually all Android devices.
In Material Design lot of new things were introduced like Material Theme, new widgets, custom shadows, vector drawables and custom animations

There are lot of UI libraries available which you can use in your application.Find out here

Material Design in Android SDK 6.0

This is my first time using Android Studio as my IDE in developing Android apps.
I see that my Android Studio's SDK is already version 6.0 (Marshmallow). My question is, by using SDK 6.0, does it already promote Material Design? As in through the SDK, it already has Material Design concepts that were introduced back in 5.0 (Lollipop). I'm planning to design my app using Material Design.
Thank you very much!
Kind of. When you create a new project in Android Studio then you will get the Material Theme by default in which your status bar will have the PrimaryColorDark and Toolbar will have the PrimaryColorLight. You can choose and modify your own themes and colors in styles.xml and colors.xml
Also if you crate a new Activity, you will have 2 options in Android Studio - Blank Activity or Empty Activity. If you choose a Blank Activity then you will get the Material design Floating Button already incorporated in your Activity's layout.
So Android Studio does try to help the developer by introducing little Material Design stuff beforehand. But as you go further you'll have to put things yourself. You might have to import the design library like this in your gradle to use some other widgets -
compile 'com.android.support:design:22.2.0'
See this link to see how to use other Material Design elements in your app.

Use the support library. It contains special themes and view components that will allow you to achieve a Material Design look in older platform versions.
Add "compile 'com.android.support:appcompat-v7:22.0.0'" to your gradle dependencies
Whenever you are using Button, Textview use v7 view elements.

Android lollipop UI in KitKat

I am developing an android app and I would like to have android l ui on it even for KitKat. I have seen apps like inbox and pushbullet to use this such as the rotation of the circle button and the status bar recolor. How do they do this?
Make use of the Android Support Library to maintain backwards compatibility.
According to the documentation:
The v7 Support Libraries r21 and above includes the following material
design features:
Material design styles for some system widgets when you apply one of
the Theme.AppCompat themes.
Color palette theme attributes in the Theme.AppCompat themes.

How to create blue horizontal line in EditText Android

As in my question title, is it a default theme in Android or I need to do it manually? I want to have it from Froyo devices and above. Any guideline or hint to achieve it?
Are you asking for the Holo theme for older Android versions than 3.0? If you do, then take look at the library HoloEverywhere: https://github.com/ChristopheVersieux/HoloEverywhere
Many developers use it and it does exactly what you expect.
