This document discusses different types of notifications in Android - Toast notifications and Status bar notifications.
Toast notifications are short-lived pop-up messages that appear on the screen without interrupting the user's workflow. Status bar notifications add an icon and optional text to the status bar and allow displaying expanded notification details. When clicked, a status bar notification can launch an activity via an intent. The document provides code examples to create and configure both types of notifications.
This chapter looks at Intents — probably the most unique and important concept in Android development. Using implicit Intents, it is possible to request an action be performed on a piece of data, enabling Android to determine which application components can best service that request. Broadcast Intents are used to announce events system wide.

Android App Development - 02 Activity and intentDiego Grancini
1. An Intent is used to communicate between components in Android and can be explicit or implicit. It contains an action, data, and optional extras.
2. An Activity provides a visual user interface and is started using an Intent. Each Activity has a lifecycle that must be managed by the developer.
3. The system uses Intent filters declared in the manifest to match Activities to Intents and start the correct Activity.
Android intents allow communication between application components and are represented as Intent objects. There are two main types of intents - explicit intents explicitly define which component should handle the intent, while implicit intents specify an action and optional data to match with registered intent filters. Intent filters define the intents a component can respond to and contain action, data, category and other elements. Actions define what the component will do, common actions include viewing data, making phone calls. Data provides content for the action using URIs or MIME types. Categories provide metadata on the intent's behavior. Flags provide instructions on how the intent should be handled. Together, intents and filters allow sharing of tasks between components and applications on Android.
This document summarizes key concepts about graphical elements, intents, and activities in Android app development:
I. Views and ViewGroups are the basic graphical elements in Android. Views occupy screen space while ViewGroups are invisible containers that define element placement. Layouts like LinearLayout are ViewGroups that organize widgets.
II. An example app interface is created with buttons, text views, and inputs. Buttons can define click behavior via listeners, methods, or implementing interfaces. Text fields read and modify content.
III. Intents pass actions and data between app components. ExplicitIntents specify started components while ImplicitIntents declare actions. Data is passed via extras. Activities can start each other and return results via

An activity represents a single screen in an Android application that allows users to interact with the app. There can be multiple activities in an app, with the main activity starting first. Key activity methods include onCreate() to initialize the activity and onPause() to handle leaving the activity. An intent is a message that allows activities and other app components to request actions from each other. Intents can be explicit, specifying the exact component, or implicit, allowing the system to choose the best match. Implicit intents are matched to apps using intent filters declared in the manifest.
Data Transfer between Activities & DatabasesMuhammad Sajid
Data Transfer between Activities & Databases, icon: This is displayed as icon for activity. You can check or save png image of name icon in drawable folder. android:icon="@drawable/icon"
• label: The label / title that appears at top in Toolbar of that particular Activity. You can check or edit label name by opening String XML file present inside Values folder
android:label = "@string/label“ or android:label = "New Activity“
Just like icon attribute, if you have not declared any label for your activity then it will be same as your parent activity
Intent allows Android components to request functionality from other components. There are explicit intents that define the specific component to call and implicit intents that specify an action without a specific component. Data can be passed between components using intents. Components declare intent filters to register the types of intents they can handle. The share intent allows sharing data with other apps like Facebook or Gmail.
Mobile Application Development -Lecture 09 & 10.pdfAbdullahMunir32
This document discusses several key concepts in mobile application development for Android, including:
- Intents allow communication between application components and activities. They can start new activities explicitly by class or implicitly by requested action.
- Adapters bind data like arrays or cursors to views in a list. The ArrayAdapter and SimpleCursorAdapter are common choices.
- Dialogs present transient messages and allow user input. They can be created from Dialog classes, with a dialog theme, or as Toasts.
- Internet access requires the INTERNET permission. URLs can be opened to get input streams for processing web resources.
The document discusses intents, broadcast receivers, and intent filters in Android. It provides examples of explicit intents that specify a component directly and implicit intents that declare an action without specifying a component. Implicit intents can be received by components that declare intent filters supporting the action, MIME type, and category. The document also discusses using intent filters in the app manifest to advertise which implicit intents an app's activities, services, and broadcast receivers can receive.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
The largest use of Asphalt is for making asphalt concrete for road surfaces. It is widely used in airports around the
world due to the sturdiness and ability to be repaired quickly, it is widely used for runways dedicated to aircraft
landing and taking off. Asphalt is normally stored and transported at 150’C or 300’F temperature

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
4. Toast Notification
• Atoast notification is a message that
popsupon the surface of the window.
• It only fills the amountof space
required for the messageandthe
user's current activity remains visible
and interactive.
• Thenotification automatically
fades in and out, anddoesnot
accept interaction events.
• Because atoast canbe created
from a backgroundService, it
appears evenif the application isn't
visible.
7. Status BarNotification
• Astatus bar notification adds anicon to the
system's status bar (with anoptional ticker- text
message) andan expandedmessage (notification
detail) in the "Notifications" window.
• Whenthe user selects the expanded message,
Android fires anIntent that is defined by the
notification (usually to launch anActivity).
• You can also configure the notification to alert the
user with a sound, a vibration, and flashing lights on
the device.
11. Code that DisplaysExpanded
Message (Notification Detail)
// Define the Notification's expandedmessage(notification detail)
// andIntent.Thenotification detail messageis the onethat gets
// displayed whena user drags the notification downward.
CharSequencecontentTitle ="Notification Details.";
CharSequencecontentText ="Goto JavaPassion.com byclicking me";
....
...
// Sets the contentView field to be a view with the standard "Latest Event"
// layout. "mPendingIntent" is anintent to launch whenthe user clicks
// the expandednotification
mNotification.setLatestEventInfo(getApplicationContext(),
contentTitle,
contentText,
mPendingIntent);
13. Code that Starts an Activitywhen
Notification Detail isclicked
// TheIntent is to define an action that gets executed when a
// user clicks the notification detail.
intent notifyIntent =new Intent(
android.content.Intent.ACTION_VIEW, Uri
.parse("http://www.javapassion.com"));
// ThePendingIntentcanbe handedto other applications so that they can
// perform the action you described on your behalf at a later time.
// Bygiving a PendingIntent to another application, you are granting it the
// right to perform the operation you have specified as if the other application
// was yourself (with the samepermissions and identity).
PendingIntent mPendingIntent = PendingIntent.getActivity(
StatusBarNotification.this, 0, notifyIntent,
android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
// Sets the contentView field to bea view with the standard "Latest Event"
// layout. "mPendingIntent" is anintent to launch when the user clicks
// the expandednotification
mNotification.setLatestEventInfo(getApplicationContext(),
contentTitle,
contentText,
14. PendingIntent
• PendingIntent is basically an object that wraps another Intent object. Then it
can be passed to a foreign application where you’re granting that app the right
to perform the operation, i.e., execute the intent as if it were executed from
your own app’s process (same permission and identity). For security reasons
you should always pass explicit intents to a PendingIntent rather than being
implicit.
• Instances of this class are created with getActivity(Context, int, Intent,
int), getBroadcast(Context, int, Intent, int), and getService(Context, int, Intent,
int); the returned object can be handed to other applications so that they can
perform the action you described on your behalf at a later time.
16. Agenda
What is Intent?
Why Intent?
Types of Intents?
How Intents are received?
How Intents are resolved?
17. What is an
Intent?
➢ It is a message passing framework that is used to carry out
interaction between Activities(and also other android
building blocks such as services and broadcast Receivers)
➢ Intent contains an action carrying some information.
➢ Intent is used to communicate between android
components.
○ To start an activity
○ To start a service
○ To deliver a broadcast.
18. • There are separate mechanisms for delivering intents to each type of component − activities,
services, and broadcast receivers.
• 1.Context.startActivity()
• The Intent object is passed to this method to launch a new activity or get an existing activity to
do something new.
• 2.Context.startService()
• The Intent object is passed to this method to initiate a service or deliver new instructions to an
ongoing service.
• 3.Context.sendBroadcast()
• The Intent object is passed to this method to deliver the message to all interested broadcast
receivers.
19. Why
Intent?
➢ Intent is used to communicate, share data
between components.
➢ Intent contains the following things.
○ Component Name
○ Action
○ Data
○ Extras
○ Category
○ Flags
20. Intent Objects
• An Intent object is a bundle of information which is used by the component that receives the
intent as well as information used by the Android system.
• An Intent object can contain the following components
• Action
• This is mandatory part of the Intent object and is a string naming the action to be performed —
or, in the case of broadcast intents, the action that took place and is being reported. The action
largely determines how the rest of the intent object is structured . The Intent class defines a
number of action constants corresponding to different intents.
• Eg: ACTION_WEB_SEARCH
• Perform a web search.
• ACTION_SEND
• Deliver some data to someone else.
• ACTION_SEARCH
• Perform a search.
• The action in an Intent object can be set by the setAction() method and read by getAction().
21. Data
• Adds a data specification to an intent filter. The specification can be just a data type (the
mimeType attribute), just a URI, or both a data type and a URI. The setData() method specifies
data only as a URI, setType() specifies it only as a MIME type, and setDataAndType() specifies it
as both a URI and a MIME type. The URI is read by getData() and the type by getType().
• Category
• The category is an optional part of Intent object and it's a string containing additional information about the
kind of component that should handle the intent. The addCategory() method places a category in an Intent
object, removeCategory() deletes a category previously added, and getCategories() gets the set of all
categories currently in the object.eg
• CATEGORY_APP_MESSAGING
• Used with ACTION_MAIN to launch the messaging application
• CATEGORY_APP_MUSIC
• Used with ACTION_MAIN to launch the music application.
• CATEGORY_DEFAULT
• Set if the activity should be an option for the default action to perform on a piece of data.
• To receive implicit intents, you must include the CATEGORY_DEFAULT category in the intent
filter. The methods startActivity() treat all intents as if they declared the CATEGORY_DEFAULT
category. If you do not declare this category in your intent filter, no implicit intents will resolve
to your activity.
22. • Extras
• This will be in key-value pairs for additional information that should be
delivered to the component handling the intent. The extras can be set and
read using the putExtras() and getExtras() methods respectively.
23. • Flags
• These flags are optional part of Intent object and instruct the Android system how to launch an activity, and
how to treat it after it's launched etc.
• FLAG_ACTIVITY_CLEAR_TASK
• If set in an Intent passed to Context.startActivity(), this flag will cause any existing task that would be
associated with the activity to be cleared before the activity is started. That is, the activity becomes the new
root of an otherwise empty task, and any old activities are finished. This can only be used in conjunction
with FLAG_ACTIVITY_NEW_TASK.
• FLAG_ACTIVITY_NEW_TASK
• This flag is generally used by activities that want to present a "launcher" style behavior: they give the user a
list of separate things that can be done, which otherwise run completely independently of the activity
launching them.
• FLAG_ACTIVITY_CLEAR_TOP
• If set, and the activity being launched is already running in the current task, then instead of launching a new
instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered
to the (now on top) old activity as a new Intent.
24. • Component Name
• This optional field is an android ComponentName object
representing either Activity, Service or BroadcastReceiver
class. If it is set, the Intent object is delivered to an instance
of the designated class otherwise Android uses other
information in the Intent object to locate a suitable target.
• The component name is set by setComponent(), setClass(),
or setClassName() and read by getComponent().
26. Explicit
Intents
➢ Used to launch a specific component like
activity or a service.
➢ In this case, android system directly
forwards this intent to that specific
component.
➢ It is faster.
➢ Always use explicit intents if you know the
specific activity or service .
27. Interaction among activities
• To navigate to an activity from another activity ,we
make use of an intent.
1. Create an intent Object with two parameter. The first
parameter is context and second parameter is the
second activity to navigate.
• Context is an object provided by Android runtime
environment to the app.It contains the global
information about the environment in which application
is running.
• 2. Pass this Intent object to startActivity() method.
28. Implicit
Intent
➢ Specifies an action that can invoke an app
on the device that can perform the action.
➢ Useful when your app can not perform the
action but other apps do and you let user to
pick up the app.
➢ Its possible that there may not be any app
that handles the implicit intent.
29. How Intents are
received?
➢ Till now we have seen how intents are used
to invoke some other components. Now lets
explore how these components receive
these intents.
➢ Receiving Implicit Intents
➢ Receiving Explicit Intents
○ Explicit Intents are directly delivered to target as
intent has the target component class specified in it.
30. Receiving Implicit
Intents
➢ Your app should advertise what intents it can
handle using <intent-filter> tag in the
manifest file under <activity> or <service> or
<receiver> tags.
➢ You can mention one or more of these three
elements under <intent-filter>
○ action
○ data
○ category
32. How Intents are
resolved?
➢ When the system receives an implicit intent,
it searches the component by comparing the
intent to intent filter based on these aspects.
○ The Intent action(Action Test)
■ Ex: ACTION_SEND
○ The Intent Category(Category Test)
■ Ex: CATEGORY_HOME
○ The Data(Data Test)
■ Ex: android:mimetype=”video/mpeg”
33. Intent Filters
• We have seen how an Intent has been used to call an another
activity. Android OS uses filters to pinpoint the set of Activities,
Services, and Broadcast receivers that can handle the Intent with
help of specified set of action, categories, data scheme associated
with an Intent.
• We will use <intent-filter> element in the manifest file to list down
actions, categories and data types associated with any activity,
service, or broadcast receiver.
