Data Storage in Andorid used to store application data in databases, files, or preferences, in internal or removeable storage. Used to add a data backup service to let users store and recover application and system data.
Android provides several options for you to save persistent application data. The solution you choose depends on your specific needs, such as whether the data should be private to your application or accessible to other applications (and the user) and how much space your data requires.

Assets, Files, and Data Parsing
Android offers a few structured ways to store data, notably SharedPreferences and local SQLite databases.
And, of course, you are welcome to store your data “in the cloud” by using an Internet-based service.
Beyond that, though, Android allows you to work with plain old ordinary files, either one baked into your app (“assets”) or ones on so-called internal or external storage.
To make those files work — and to consume data off of the Internet — you will likely need to employ a parser. Android ships with several choices for XML and JSON parsing, in addition to third-party libraries you can attempt to use.
This session focuses on Assets, Raw, and Files.
SQLite Database in Android used to store persistent data. If you want to store some data into local storage then SQLite Database is the most common storage option. It is lightweight database that comes with Android OS.
Video Streaming: from the native Android player to unconventional devicesAlessandro Martellucci
Getting a streaming video in your Android smartphone or tablet is no longer enough.In the latest period, Google shows how to push this concept forward to new appliances. Chromecast and Android TV are two of the most promising gadgets for upsetting the way users enjoy video streaming.
This talk we’ll give you an overview about the streaming in Android. Starting from video streaming on mobile devices, we will guide you into the evolution of the development through Chromecast up to Android TV. Matteo Bonifazi and Alessandro Martellucci will be illustrating this talk with their experiences developing mobile television applications for the main Italian broadcaster providers.

Storing data is a basic and very common need in mobile apps. The Android application framework provides several storage options, one of which is SQLite databases.
In this tutorial you will see a simple Android database example. The example is based on the Android ListView Tutorial and the Android AsyncTask Tutorial, however these tutorials are not mandatory for the purpose of understanding the principles of proper Android database usage.
Almost every Android app has some tasks that need to be executed in the background, such as network operations and CPU intensive operations. Many times these tasks are required by the UI thread, however executing them in the UI the will compromise the responsiveness of the app.
The AsyncTask class is is a convenience generic abstract class for executing relatively short tasks in a background thread and updating the UI thread. AsyncTask has 3 type parameters:
Params - the class of the params array that is passed to the execute() method which is called in the UI thread and received in the doInBackground() method which is called in the background thread.
Progress - the class of the values array that is passed by the publishProgress() method which is called in the background thread and returned by the onProgressUpdate() method which is called in the UI thread.
Result - the class of the result that is passed returned by the execute() method and returned by the onPostExecute() method which is called in the UI thread.
The doInBackground() method is an abstract method that defines the actual background task.
All'interno delle slide vedremo alcune informazioni circa il programma MSP (Microsoft Student Partners), Microsoft Azure, Microsoft Imagine (ex DreamSpark), Sviluppo Mobile, Xamarin e Xamarin Forms. Utilizzeremo questi strumenti per realizzare un'applicazione Cross-Platform che può essere eseguita su Android, Windows Phone 8.1, Windows 8.1 e Windows 10 (UWP).

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Honest Reviews of Tim Han LMA Course Program.pptxtimhan337
Personal development courses are widely available today, with each one promising life-changing outcomes. Tim Han’s Life Mastery Achievers (LMA) Course has drawn a lot of interest. In addition to offering my frank assessment of Success Insider’s LMA Course, this piece examines the course’s effects via a variety of Tim Han LMA course reviews and Success Insider comments.
3. Shared Preferences
• The SharedPreferences class provides a general framework that allows
you to save and retrieve persistent key-value pairs of primitive data types.
• You can save any primitive data: booleans, floats, ints, longs, and strings.
This data will persist across user sessions (even if your application is
killed).
• use one of two methods:
– getSharedPreferences() - Use this if you need multiple preferences files
identified by name.
– getPreferences() - Use this if you need only one preferences.
• Call edit() to get a SharedPreferences.Editor
• Add values with methods such as putBoolean() and putString().
• Commit the new values with commit()
• To read values - getBoolean() and getString()
4. Internal Storage
• You can save files directly on the device's internal storage. By default, files
saved to the internal storage are private to your application and other
applications cannot access them (nor can the user). When the user
uninstalls your application, these files are removed.
• To create and write a private file
– Call openFileOutput() with the name of the file and the operating mode. This
returns a FileOutputStream
– Write to the file with write()
– Close the stream with close()
• To read a file
– Call openFileInput() and pass it the name of the file
– Read bytes from the file with read()
– Then close the stream with close()
• Other useful methods: getFilesDir(), getDir(), deleteFile(), fileList()
5. External Storage
– Checking media availability - Before you do any work with the
external storage, you should always call getExternalStorageState() to
check whether the media is available.
– Accessing files on external storage
• If you're using API Level 8 or greater, use getExternalFilesDir() to open a File
• If you're using API Level 7 or lower, use getExternalStorageDirectory()
– You should then write your data in the following directory:
• /Android/data/<package_name>/files/
• If the user's device is running API Level 8 or greater and they uninstall your
application, this directory and all its contents will be deleted.
– Hiding your files from the Media Scanner
• Include an empty file named .nomedia in your external files directory
6. External Storage
– Saving files that should be shared - These directories lay at the root of
the external storage
• Music/ - Media scanner classifies all media found here as user music.
• Podcasts/ - Media scanner classifies all media found here as a podcast.
• Ringtones/ - Media scanner classifies all media found here as a ringtone.
• Alarms/ - Media scanner classifies all media found here as an alarm sound.
• Notifications/ - Media scanner classifies all media found here as a notification
sound.
• Pictures/ - All photos (excluding those taken with the camera).
• Movies/ - All movies (excluding those taken with the camcorder).
• Download/ - Miscellaneous downloads.
– Getting Shared Files
• In API Level 8 or greater, use getExternalStoragePublicDirectory(), passing it the
type of public directory you want, such as DIRECTORY_MUSIC,
• If you're using API Level 7 or lower, use getExternalStorageDirectory()
7. SQLite Database
– Android provides full support for SQLite databases. Any databases you
create will be accessible by name to any class in the application, but
not outside the application.
– to create a new SQLite database is to create a subclass of
SQLiteOpenHelper and override the onCreate() method. You should
use it to Create Table
– To Upgrade your database use onUpgrade() method. You should use it
to Alter Table

Content Provider 1
Data can be shared over different applications
Content Provider Basics
1. There are no common storage area that all Android application can access.
2. The only way: to share data across applications: Content Provider
3. Content providers store and retrieve data and make it accessible to all
applications.
Content Provider 2
9. Android Content Provider
Content Provider Basics (Contd.)
Android ships with a number of content providers for common data types:
1. Audio
2. Video
3. Images
4. Personal contact information etc
Content Provider provides the way to share the data between multiple applications.
For example, contact data is used by multiple applications (Dialer, Messaging etc.)
and must be stored in Content Provider to have common access.
A content provider is a class that implements a standard set of methods to let other
applications store and retrieve the type of data that is handled by that content provider.

App 2
10. Android Content Provider
Querying Data
Content Provide: URI
1. Each content provider exposes a public URI that uniquely identifies its data set.
2. A content provider that controls multiple data sets (multiple tables) exposes a
separate URI for each one.
3. All URIs for providers begin with the string "content://".
The content: scheme identifies the data as being controlled by a content provider.
URI samples:
<standard_prefix>://<authority>/<data_path>/<id>
For example, to retrieve all the bookmarks stored by our web browsers (in Android):
content://browser/bookmarks
Similarly, to retrieve all the contacts stored by the Contacts application:
content://contacts/people
To retrieve a particular contact, you can specify the URI with a specific ID:
content://contacts/people/3
11. Android Content Provider
Content Provide: URI
So we need three pieces of information to query a content provider:
1. The URI that identifies the provider
2. The names of the data fields you want to receive
3. The data types for those fields
If we are querying a particular record, you also need the ID for that record.
Some more examples:
content://media/internal/images URI return the list of all internal images on the device.
content://contacts/people/ URI return the list of all contact names on the device.
content://contacts/people/45 URI return the single result row, the contact with ID=45.
