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.

Human + Machine Learning : Oredev Human Centered Machine LearningMike Wolfson
Key takeaways
You will learn how to identify and plan for bias in Machine Learning applications
You will learn about how to implement a series of specific steps in any software projects to understand how the data in your systems.
As we use Machine Learning in our software - we need to understand the impact on what we build. The Design team at Google has created a framework named Human-Centered Machine Learning (HCML) to help us focus and guide that understanding. I will introduce this concept and show how you can use it in your development process. I will show how HCML can be used to answer important questions like: Is ML right for this problem? What unique solution does ML provide? Are we using the right information to train our system? What is the impact of wrong results? Just like with the web and mobile revolutions, ML will force us to consider new possibilities for every experience we build. We must stay grounded in human needs while solving them in unique ways. HCML provides techniques to help us accomplish this.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Open: - Android does not differentiate between the phone's core applications and third-party applications ; Developers have full access to the same framework APIs used by the core applications. The application architecture is designed to simplify the reuse of components; any application can publish its capabilities and any other application may then make use of those capabilities (subject to security constraints enforced by the framework). This same mechanism allows components to be replaced by the user. -Independent developers are also allowed to create applications that replace core phone functionality (like dialer, browser, contacts list, home screen, etc). Low Barrier to entry Easy to develop -Programming model is based on Java. Applications are written in Java, and just call new APIs. Tools used are based on existing most used tools (Eclipse). Also allows development without using Eclipse (if you would prefer command line – can use adb, etc). -Can run development tools on Windows, Linux, and OSX. Open Market -Very minimal oversight over what can be sold (mostly regarding security, or explicit material). You can publish replacements for any of the core applications (including the keyboard, or browser). -All applications are equal Feature Rich Platform -Multitasking -Access to native phone events (SMS, Phone ringing, etc) -3 rd Party APIs -UI Customization -Interpreted language support allowed (Python, JS, Ruby, etc) -Flash

Other Tools: android To create/update Android projects and to create/move/delete AVDs. Android Emulator To run your Android applications on an emulated Android platform. Android Debug Bridge To interface with your emulator or connected device (install apps, shell the device, issue commands, etc.).
Android (android.bat) – command line tool to allow developer to manage SDK and AVDs Emulator (Mobile device emulator) -- a virtual mobile device that runs on your computer. The emulator lets you prototype, develop, and test Android applications without using a physical device. Each AVD is made up of: A hardware profile. You can set options to define the hardware features of the virtual device. For example, you can define whether the device has a camera, whether it uses a physical QWERTY keyboard or a dialing pad, how much memory it has, and so on. A mapping to a system image. You can define what version of the Android platform will run on the virtual device. You can choose a version of the standard Android platform or the system image packaged with an SDK add-on. Other options. You can specify the emulator skin you want to use with the AVD, which lets you control the screen dimensions, appearance , and so on. You can also specify the emulated SD card to use with the AVD. A dedicated storage area on your development machine, in which is stored the device's user data (installed applications, settings, and so on) and emulated SD card. ADB: Android Debug Bridge (adb) is a versatile tool lets you manage the state of an emulator instance or Android-powered device. It is a client-server program that includes three components: A client, which runs on your development machine. You can invoke a client from a shell by issuing an adb command. Other Android tools such as the ADT plugin and DDMS also create adb clients. A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device. A daemon, which runs as a background process on each emulator or device instance. DDMS: Includes: file explorer; Memory/Thread inspector (dumpsys, dumpstate); tools to execute Garbage Collection; Screen capture;
http://developer.android.com/resources/tutorials/hello-world.html Steps to create a new project. Once you complete the New Project Wizard, ADT creates the following folders and files in your new project: src/ Includes your stub Activity Java file. All other Java files for your application go here. <Android Version> / (e.g., Android 1.1/) Includes the android.jar file that your application will build against. This is determined by the build target that you have chosen in the New Project Wizard . gen/ This contains the Java files generated by ADT, such as your R.java file and interfaces created from AIDL files. assets/ This is empty. You can use it to store raw asset files. See Resources and Assets . res/ A folder for your application resources, such as drawable files, layout files, string values, etc. See Resources and Assets . AndroidManifest.xml The Android Manifest for your project. See The AndroidManifest.xml File . default.properties This file contains project settings, such as the build target. This files is integral to the project, as such, it should be maintained in a Source Revision Control system. It should never be edited manually — to edit project properties, right-click the project folder and select &quot;Properties&quot;.
Activity – (Noun) A single screen, your application is made up of one or more of these Intent – (Verb) code to perform an action – used to call an activity, service or broadcast receiver; this is the wiring between activities; Intent messaging is a facility for late run-time binding between components in the same or different applications Resource – text, pictures, sound, etc; These things are all abstracted from the code, and compiled into a class called R.class Manifest File – always named AndroidManifest.xml – bundled into .apk file (that contains the applications code, files, and resources), declares the components of an application, describes security permissions required by the app, and lists required library dependancies. Widget – miniature application views that can be embedded in other applications (such as the home screen), and receive periodic updates Service – a task that can be running, but is not visible (background apps FTW!) Broadcast Receiver – a component that does nothing but receive and react to broadcast announcements. These don’t contain a UI, but could be used to start an activity when an event triggers it. Ex. Listed for timezone, or low battery warnings. Security and Permissions - A central design point of the Android security architecture is that no application, by default, has permission to perform any operations that would adversely impact other applications, the operating system, or the user. Android is a multi-process system, in which each application (and parts of the system) runs in its own process. Most security between applications and the system is enforced at the process level through standard Linux facilities, such as user and group IDs that are assigned to applications. Additional finer-grained security features are provided through a &quot;permission&quot; mechanism that enforces restrictions on the specific operations that a particular process can perform, and per-URI permissions for granting ad-hoc access to specific pieces of data. A basic Android application has no permissions associated with it, meaning it can not do anything that would adversely impact the user experience or any data on the device. To make use of protected features of the device, you must include in your AndroidManifest.xml one or more <uses-permission> tags declaring the permissions that your application needs. Content Provider – Functionality designed to allow data to be shared across applications. It is data and an API that any app can access; Android uses this feature to provide contact info; they can be accessed through the android.provider package (some require permissions to access)
LinearLayout – arranges children in a single row/column. FrameLayout – arranges children so they show up at the top left. Commonly used for Activities with a single element, or tabbed views RelativeLayout – elements are arranges in relation to each other. (Element X is above Y). TableLayout – elements arranged in cells (like HTML tables)
Activity – (Noun) A single screen, your application is made up of one or more of these
