This document provides instructions for telling time on an analog clock. It explains that the long hand is the minute hand and the short hand is the hour hand. It teaches that the numbers around the clock represent 5-minute intervals and can be used to count by 5s to determine the number of minutes past the hour. Several examples are given of using this method to read times shown on the clock. The document also discusses concepts like quarter hours, half hours, and handling times just before a new hour.
The document provides examples of telling time in hours, minutes and periods of the day (am and pm). It lists times such as "three o'clock", "twenty to one", "ten past ten", and accompanies each with the question "What time is it?". It then prompts the reader to choose the correct clock face for times including "half past five", "a quarter past nine", and "midday".
This document provides instructions on how to tell time on both analogue and digital clocks. It explains that analogue clocks have numbers 1-12 around the face representing hours, and lines representing minutes. It teaches that the small hand points to the hours and big hand points to the minutes. The document breaks down telling time into hours, half hours, quarters of an hour. It also explains how to tell time using A.M. and P.M. on both analogue and digital clocks. An interactive game is provided to match analogue and digital clocks.

The document discusses time management (TM) and how to manage time effectively. It defines TM as allocating the right time to the right activities. TM is needed to save time, reduce stress, function effectively, increase work output, and have more control over responsibilities. Effective TM involves planning, setting goals and deadlines, prioritizing activities, delegating work, and spending the right amount of time on tasks. The process of TM starts with costing your time, making activity logs, setting goals, planning, prioritizing, and scheduling.
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.
This document provides an overview of Android application components and activities. It discusses that an Android app must have at least one component such as an activity, intent, broadcast receiver, service, or content provider. Activities provide the user interface and run in the foreground of an app. Activities have a lifecycle with callback methods that get triggered during state changes like onCreate, onStart, onResume. Intents are used to start activities and services, and can be explicit or implicit. The document also covers how to start an activity using an intent, activity states, and how the Android system resolves implicit intents.
The document discusses activities, intents, and event listeners in Android. It defines an activity as a single focused thing the user can interact with and explains the activity lifecycle including methods like onCreate, onStart, onResume, etc. It describes intents as messages that allow communication between app components and how they are used to start activities. It also defines event listeners as a way to handle user interactions and collect data on events like button presses. It provides examples of registering different types of event listeners including anonymous inner classes and having the activity implement listener interfaces.

This document discusses the core application components in Android:
1) Activities represent single screens and are independent of each other. The activity lifecycle callbacks like onCreate(), onStart(), onResume(), onPause(), onStop(), and onDestroy() are explained.
2) Services run in the background to perform long-running tasks without a user interface.
3) Content providers allow data sharing between applications by hiding database details.
4) Broadcast receivers respond to broadcast messages from other apps or the system to perform tasks when apps are not active. The document provides examples of how to implement each component.

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.
Intent, Service and BroadcastReciver (2).pptBirukMarkos
This document discusses intents, services, and broadcast receivers in Android mobile application development. It defines intents as asynchronous messages that allow application components to request functionality from other Android components. It describes the main components of an intent like the action, data, category, extras, and flags. It also explains the differences between explicit and implicit intents and provides examples of common intent actions. Finally, it provides an overview of services and their life cycle as well as broadcasts in Android.
Intents allow communication between components in Android. They can be explicit, naming a specific component, or implicit, specifying an action for Android to resolve. Intents can share data between components via extras. Components declare intent filters to specify the intents they can handle. Developers can define intents to reuse functionality from other apps or expose functionality to other apps. Intents are a core part of Android that enable reuse and interoperability.
There are four main types of application components in Android: activities which represent a single screen in the app, services which run in the background, broadcast receivers which allow the app to respond to system-wide events, and content providers which manage shared app data. The manifest file declares these components and their permissions. The activity lifecycle handles navigating between activities, saving and restoring state, and sending data between components within and between processes.
The document discusses intents and intent filters in Android. It explains that intents are messages used to start activities, services, and broadcast receivers. Intents contain action, data, category and other fields. Components specify intent filters to describe the intents they can handle. The Android system uses intent resolution to match implicit intents to components based on comparing the intent fields to the filter specifications. Key concepts covered include explicit vs implicit intents, intent filter structure and matching, and special cases for MAIN and LAUNCHER filters.

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.
This document discusses key concepts for mobile application development on Android including activities, layouts, menus, dialogs, intents, notifications, and services. It describes how to create an activity by extending the Activity class and setting the user interface. It also explains the different types of layouts, menus, and dialogs available in Android and how to implement them.
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

2. Intents
• An intent is an abstract description of an operation to be performed.
• Late runtime binding between the code in different applications is
performed by the use of Intents.
• Its most significant use is in the launching of activities.
3. Switching between Activities
• Any Android application will comprise of many activities.
• How do they Interact with one another.
Intent intent = new Intent(CallingActivity.this, NewActivity.class);
startActivity(intent);
4. Passing Data-Using Intent Extras
• Any Android application will comprise of many activities.
• Data needs to be send from one activity to another.
Intent intent = new Intent(CallingActivity.this, NewActivity.class);
Use intent.putExtra(“key", val);
startActivity(intent);
5. Bundle
• Bundle is generally used for passing data between Activities. It can hold all
types of values and can pass them to the new activity.
• You can receive data in another Activity like this:
Bundle extras = intent.getExtras();
String dataReceived = extras.getString(“key");
6. Shared Preferences
• Provides a way to capture user preferences on the settings of
a specific application or an activity
• Preferences are typically name value pairs
9. What is Activity Result?
• Most application consists of multiple activities.
• There comes a need for getting some result form the called
activity
• Could be the list item selected on any activity etc.
10. Usage
• Call the StartactivityForResult() from the calling Activity with a
unique request code.
• Create the overridden method OnActivityResult() in the calling
Activity.
• Set the result to RESULT_OK with the selection stored in the
intent.
14. NotificationManager
• To show notifications we use NotificationManager Class
– NotificationManager notificationManager = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE);
• We use a PendingIntent to specify the action which should be
performed once the user select the notification.
• You can Receive the activity via PendingIntent.getActivity()
15. Notification Extras
• Notification.Builder allows to define actions to the
notification.
• A PendingIntent itself is simply a reference to a token
maintained by the system.
• This means that, even if its owning application's process
is killed, the PendingIntent itself will remain usable from
other processes.
18. Android Media Player
• MediaPlayer is the easier way, if you just want to play an
audio file in the background, somewhere in an application
• MediaPlayer class can be used to control playback of
audio/video files and streams
Java compilers convert your code from human readable Java source files to something called “bytecode” in the Java world. “Bytecode” is interpreted by a JVM, which operates much like a physical CPU might operate on machine code, to actually execute the compiled code. Performance - Java performance in generally second only to C/C++ in common language performance comparisons. In the Java programming language and environment, a just-in-time (JIT) compiler is a program that turns Java bytecode (a program that contains instructions that must be interpreted) into instructions that can be sent directly to the processor.The just-in-time compiler comes with the virtual machine and is used optionally. It compiles the bytecode into platform-specific executable code that is immediately executed
such as development toolkits for other programming languages, and can write and contribute their own plug-in modules.
A PendingIntent itself is simply a reference to a token maintained by the system describing the original data used to retrieve it. This means that, even if its owning application's process is killed, the PendingIntent itself will remain usable from other processes that have been given it. If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it.
