- InApp Purchase:-
Ans:- Used to purchase or Subscribe a product or Service from google play store.
Main 3 Callback important in InApp-Purchase
1) PurChaseFinish Listener = Call when finish purchase process.
2) QueryInventory Listener- Call every time InApp Activity Call. Gives Desription about Product weather it is Purchased or not in past, it's price, trancation id, date (if Purchased) or any other details
3) ConsumeFinishListener - There are 2 types of Product Consumable and non-consumable. Consumable Product are Consume by code. And It's successfully give response after consume in this callback Listener.

- Intent
Ans:- Explicit intents specify the component to start by name (the fully-qualified class name). You'll typically use an explicit intent to start a component in your own app, because you know the class name of the activity or service you want to start. For example, you can start a new activity in response to a user action or start a service to download a file in the background.
Implicit intents do not name a specific component, but instead declare a general action to perform, which allows a component from another app to handle it. For example, if you want to show the user a location on a map, you can use an implicit intent to request that another capable app show a specified location on a map.

- Adapter used with RecyclerView
Ans:- RecyclerView.Adapter<ViewHolder>
- Difference between RelativeLayout and FrameLayout
Ans:-
FrameLayout - designed to display a stack of child View controls. Multiple view controls can be added to this layout. This can be used to show multiple controls within the same screen space.
RelativeLayout - designed to display child View controls in relation to each other. For instance, you can set a control to be positioned “above” or “below” or “to the left of” or “to the right of” another control, referred to by its unique identifier. You can also align child View controls relative to the parent edges.

============================ New Layouts =======================================================================================================================================================================================================================================================================================================
- AppBarLayout
Like whatsapp, on scrolling of listview, automatically toolbar gets hidden. This can be achieved using the Android AppBarLayout, Use this layout to hide the actionbar or appbar when the sibling view is scrolled.
- NestedScrollView
NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
- CoordinatorLayout
The CoordinatorLayout is a super-powered FrameLayout (according to the official documentation). Child views can also interact with one another.
By default, if you add multiple children to a FrameLayout, they would overlap each other. A FrameLayout should be used most often to hold a single child view. The main appeal of the CoordinatorLayout is its ability to coordinate the animations and transitions of the views within it. Using xml only, you can describe a layout where a FAB moves out of the way of an incoming Snackbar, for example, or have a FAB (or any other View really) that is apparently attached to another widget, and moves on screen with the widget.
================Collection In Java=========================================
- Collection in Java
Ans:- http://beginnersbook.com/java-collections-tutorials/
ArrayList:-
Arraylist maintains the insertion order.
Elements gets sorted in the same sequence in which they have been added to the Arraylist.
Searching abject is very easy. get and set process of object is also easy.
LinkedList:-
LinkedList almost same as ArrayList.
Search Process is slow than Arrtaylist.
Deletation process of object is very fast compare to Arraylist.
Insertion process fast compare to ArrayList.
Vector:-
Vector gives poor permance of searching, adding, delete and update of its elements.
Maintain Insertion order like ArrayList.
HashMap:-
HashMap maintains key and value pairs.
It is not an ordered collection which means it does not return the keys and values in the same order in which they have been inserted into the HashMap.
It neither does any kind of sorting to the stored keys and Values.
TreeMap:-
TreeMap maintains key and value pairs.
TreeMap is sorted according to the natural ordering of its keys.
LinkedHashMap:-
TreeMap maintains key and value pairs.
LinkedHashMap maintains the insertion order.
HashSet:-
HashSet doesn’t maintain any kind of order of its elements.
HashSet doesn’t allow duplicates.
If you try to add a duplicate element in HashSet, the old value would be overwritten.
TreeSet:-
TreeSet sorts the elements in ascending order.
TreeSet is similar to HashSet except that it sorts the elements in the ascending order while HashSet doesn’t maintain any order
LinkedHashSet:-
LinkedHashSet maintains the insertion order.
Elements gets sorted in the same sequence in which they have been added to the Set Like Arraylist
