An Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map.
Each activity is given a window in which to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows.
An application usually consists of multiple activities that are loosely bound to each other. Typically, one activity in an application is specified as the "main" activity, which is presented to the user when launching the application for the first time. Each activity can then start another activity in order to perform different actions.
Each time a new activity starts, the previous activity is stopped, but the system preserves the activity in a stack .
When a new activity starts, it is pushed onto the back stack and takes user focus.

The presentation deals with the problem of persistence when writing Android applications. After a general discussion on the capabilities of SQLite, the repository pattern (which allows the centralization all persistence concerns) is introduced. Then, the lifecycle of the SQLiteOpenHelper class is discussed, including how to correctly account for changes in the database schema between application updates. Finally, the concept of object-relational mapping (ORM) is introduced, together with a discussion and how the repository pattern helps isolating such a concern from the business logic code.
In a world where users have ever higher expectations from the apps they use, having data always available, even when the device is offline has become increasingly important.
In this talk we will go through different ways of saving data on the phone and introduce Realm as a replacement for SQLite and ORM's.
Through an example app it will be demonstrated that thinking "Offline first" not only affects your apps architecture for the better, but also results in happier users.

Json stands for Java script Object Notation and Gson is like json which is developed bye Google. Jackson is also one type of Json which works similar to json. in this slide i am showing The performance comparison between Json, Gson and Jackson.
Databases are the prime technique used to develop any information system used in modern business. There are many different types of database available used for different purposes.
This set of slides introduces the reader to the concepts of Android Activities and Views. After presenting these two concepts in general terms, it continues with a detailed description of the activity lifecycle. It follows a discussion on how to structure the user interface in terms of View and ViewGroup objects. Finally, the presentation shows how to frame Android application development within the dictates of the Model-View-Controller (MVC) pattern.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
5. Activity Lifecycle Overview
An application consists of one or more
components that are defined in the
application's manifest file. A component can
be one of the following:
1. An Activity
2. A Service
3. A broadcast receiver
4. A content provider
5/30/2015 5
6. Activity Lifecycle Overview
• An activity usually presents a single visual user
interface from which a number of actions could be
performed.
• Although activities work together to form a cohesive
user interface, each activity is independent of the
others.
• Typically, one of the activities is marked as the first one
that should be presented to the user when the
application is launched.
• Moving from one activity to another is accomplished
by having the current activity start the next one
through so called intents.
5/30/2015 6
7. Activity Lifecycle Overview(Service)
• A service doesn't have a visual user interface,
but rather runs in the background for an
indefinite period of time.
5/30/2015 7
8. Activity Lifecycle Overview(Broadcast receiver)
A broadcast receiver is a component that does
nothing but receive and react to broadcast
announcements.
Broadcast receivers do not display a user
interface. However, they may start an activity
in response to the information they receive, or
‐ as services do ‐ they may use the notification
manager to alert the user.
5/30/2015 8
9. Android Applications
• Every Android application runs in its own
process(with its own instance of the Dalvik virtual
machine)
Whenever there's a request that should be
handled by a particular component
Android makes sure that the application process
of the component is running,
starting it if necessary, and
that an appropriate instance of the component is
available, creating the instance if necessary.

10. Activity Stack
• Activities in the system are managed as an activity
stack.
• When a new activity is started, it is placed on the
top of the stack and becomes the running activity
‐‐ the previous activity always remains below it in
the stack, and will not come to the foreground
again until the new activity exits.
• If the user presses the Back Button the next
activity on the stack moves up and becomes
active.
5/30/2015 10
14. Life Cycle States
1. It is active or running when it is in the
foreground of the screen(at the top of the
activity stack for the current task).This is the
activity that is the focus for the user's actions.
5/30/2015 14
15. Life Cycle States
2. It is paused if it has lost focus but is still
visible to the user. That is, another activity lies
on top of it and that new activity either is
transparent or doesn't cover the full screen.
But can be killed by the system in extreme low
memory situations.
5/30/2015 15
16. Life Cycle States
3. It is stopped if it is completely obscured by
another activity. It still retains all state and
member information. However, it is no longer
visible to the user so its window is hidden and
it will often be killed by the system when
memory is needed elsewhere.
5/30/2015 16
17. Life Cycle Methods
Method: onCreate()
• Called when the activity is first created.
• This is where you should do all of your normal
static set up —create views, bind data to lists, and
so on.
• This method is passed a Bundle object containing
the activity's previous state, if that state was
captured.
• Always followed by onStart()
5/30/2015 17
18. Life Cycle Methods
Method: onStart()
Called just before the activity becomes visible
to the user.
Followed by onResume() if the activity comes
to the foreground,or onStop() if it becomes
hidden.
5/30/2015 18
19. Life Cycle Methods
Method: onRestart()
• Called after the activity has been stopped, just
prior to it being started again.
• Always followed by onStart()
5/30/2015 19
20. Life Cycle Methods
Method: onResume()
1. Called just before the activity starts
interacting with the user.
2. At this point the activity is at the top of the
activity stack, with user input going to it.
3. Always followed by onPause().
5/30/2015 20
21. Life Cycle Methods
Method: onStop()
1. Called when the activity is no longer visible to the
user.
2. This may happen because it is being destroyed,
or because another activity (either an existing
one or a new one) has been resumed and is
covering it.
3. Followed either by onRestart() if the activity is
coming back to interact with the user, or by
onDestroy() if this activity is going away.
4. The activity in this state is killable by the system.
5/30/2015 21
22. Life Cycle Methods
Method: onDestroy()
1. Called before the activity is destroyed.
2. This is the final call that the activity will receive.
3. It could be called either because the activity is
finishing (someone called finish() on it), or
because the system is temporarily destroying this
instance of the activity to save space.
4. You can distinguish between these two scenarios
with the isFinishing() method.
5. The activity in this state is killable by the system.
