Vpn presentation
Virtual private networks (VPNs) allow employees to securely access a company's intranet from remote locations over the public Internet. VPNs use encryption and tunneling protocols to create a private network across a public network like the Internet. This allows employees to access the company network from anywhere while also saving costs compared to traditional private networks by reducing equipment and maintenance expenses. VPNs authenticate users, control access, ensure confidentiality of data during transmission, and verify data integrity using encryption, digital signatures, and tunneling protocols like IPsec, L2TP, and PPTP. While VPNs provide cost savings and mobility, they also require careful deployment and management to address security issues arising from the use of public networks.
Event handling
Event handling involves responding to user actions like clicking buttons or typing text. Events are generated by sources like buttons or keyboards and handled by listeners that implement specific event listener interfaces. The listener is registered with the source to receive notifications when events occur, then processes the event by implementing callback methods defined in the listener interface. Common types of events include action events, item events, and mouse events.

Ai and using ml in mobile apps
I gave a talk on the basics of Artificial Intelligence and Machine Learning in Android Developers Meetup in Gurgaon, India.
In this session I explained the basics of AI/ML, how ML is different from AI and also give brief introduction to Deep learning. I explained how ML works and what are basic types of ML - Supervised Learning, unsupervised learning and Reinforcement learning. What are the applications and most recent prominent examples of ML. And then I moved on to introduce the major frameworks for developers in this field. I gave brief introduction to Google Cloud vision, OpenCV, Pytorch, AWS Rekognition and finally ML Kit from Google. I explained ML kit in detail and how developers can use it. I also gave a demo on ML kit.
AI in image recognition
The document discusses image recognition capabilities of Google Vision and Amazon Rekognition and how they can be used in a mobile app called Fastra. Google Vision can understand image content, detect objects, faces, logos and texts. It can also search image content online, detect inappropriate content, facial expressions and landmarks. Amazon Rekognition also allows video analysis, facial analysis, celebrity recognition and text detection in images. Some ideas mentioned are automatic tagging, emotion-based suggestions, landmark-based categories, filters, celebrity recognition and linking to trends for the Fastra app.

Android Starting App Development
The document provides an overview of Android architecture and app development. It discusses that Android is built on a Linux kernel and consists of libraries, runtime, and core applications. It also covers creating layouts with UI components like ImageView, EditText, Button. Additionally, it summarizes running and debugging apps, activity navigation, and the activity lifecycle.
Android one, why it is important for Android developers in India
Android One aims to bring affordable smartphones running stock Android to developing markets, expanding the potential audience for developers. By addressing issues with hardware, software, and connectivity in rural areas, Android One phones target the "Next 5 Billion" users and provide developers access to a larger, more diverse customer base, including those in small towns who are increasing using their phones for social networking and mobile commerce in local languages on the latest Android versions.
Clean code, Better coding practices
Why is there so much emphasis on reading the code rather than writing?
Because:
Ratio of time spent reading vs. writing code is well over 10:1
So if we are spending 1 hour writing code, on an average we have to spend 10 hours reading some code. Each time we change in logic of some code, add or remove some feature, resolve some bug, understand the context of what is going on, or just use a third party API, what we do? We READ code.
At HomeShop18, we strive for clean code.
Android enterprise application development
This document discusses how Android fits into the enterprise workplace by providing security features and APIs for managing devices. It describes how IT departments demand data security, device management and controlled application deployment from employee phones. The Device Administration API allows "security aware" apps to enforce policies like password requirements, remote wiping of devices and disabling of features. Key aspects of the API include DeviceAdminReceiver for handling events, DevicePolicyManager for managing policies, and metadata for defining allowed usage policies.
Near field communication
NFC is a short-range wireless technology that allows data exchange when devices are touched or brought within close proximity of each other. It can be used for tasks like sharing contacts, photos, and files between devices; making payments; and accessing information from tags. NFC is supported by many Android devices and Google is promoting its use in applications like Android Beam and Google Wallet for tasks like sharing content easily between devices, and making mobile payments at stores by tapping phones. The technology is expected to see significantly increased adoption in the coming years.

Android Connecting to Internet
- 2. Today’s agenda Why Connect to Internet? How to Connect to Internet? Getting Data from Server.
- 3. Why Connect to Internet? Two modes of apps: ● Standalone apps - Reminder/notes app, Photo editing app, Contacts app, Music Player app. ● Connected apps - Chatting app, Food ordering app, News app, Banking apps, Maps app. Standalone apps More Power
- 4. Standalone Apps Sync with server. Access from anywhere. Share with friends. Save in your account. Upload on server as backup. Access from anywhere. Search for online music, search for song lyrics. Save preferences online. Contacts app Music Player App Reminder/notes app Photo Editing app Ads Analytics Crash reports Push Notifications
- 5. Connecting to Network Wi-fi: Low cost or free, high speed, large volume of data available. 3g/4g/LTE: Very Expensive, Speed may be high or low, low data volume. Local Area Network: Connectivity to web may not be available, high speed, free.
- 6. Connecting to Internet Permissions: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
- 7. Connecting to Internet Checking connection status: ConnectivityManager mgr= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); if (networkInfo != null && networkInfo.isConnected()) { // fetch data } else { // display error } ● Tells about network state ● Also notify about changes in the state
- 8. Getting Data from Server 1. Create URL. 1. Create Connection using “HttpUrlConnection”. 1. Start Connection. 1. Read Data from Connection. URL url = new URL(myurl); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.connect(); InputStream is = conn.getInputStream();
- 9. Code URL url = new URL(myurl); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.connect(); InputStream is = conn.getInputStream();
- 10. URL “A Uniform Resource Locator that identifies the location of an Internet resource.” http://dailynews.com:8080/directory/file?search Protocol http Host Daiynews.com Port 8080 Path /directory/File Query search String myurl = “http://facebook.com” URL url = new URL(myurl);
- 11. HttpUrlConnection “It is used to send and receive data over the web.” “Data may be of any length.” “Can be used to GET and POST data.” HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
- 12. Get Data URL url = new URL(myurl); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setRequestMethod("GET"); conn.connect(); int responseCode = conn.getResponseCode(); // check if responseCode is 200 InputStream is = conn.getInputStream(); String responseData = readResponse(is); // Convert the InputStream into a string return responseData;
- 13. Next.. Why it is important to run network operations on separate thread? How to show network response in UI? Parsing different data formats: Json, Images. Handling common issues.
