Android is an open source software stack for mobile devices. It was founded in 2003 by Android Inc which was later acquired by Google in 2005. It includes an operating system, middleware and key applications. Some key points about Android include:
- It uses an open source Linux kernel but is not Linux itself as it does not have all typical Linux utilities.
- Applications are written in Java and compiled into Android packages that run on the Dalvik virtual machine.
- The Android SDK provides tools for application development using Java and resources for graphics, layouts etc.
- It has features like telephony, Bluetooth, WiFi, camera, GPS support and integrated browser based on WebKit.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Answer from Google , my addition – opensourceAdvantage of open source : better understanding , better code , more & better reuse - I extended an AsyncTask Class to make it a Async HTTP Class which handled all the network interactionmajority of the Android software is licensed with Apache 2.0. there may be exceptions which will be handled on a case-by-case basis. For example, the Linux kernel patches are under the GPLv2 license with system exceptions, which can be found on kernel.org.The Apache License requires preservation of the copyright notice and disclaimer, but it is not a copyleft license — it allows use of the source code for the development of proprietary software as well as free and open source software. The GPL is the first copyleft license for general use, which means that derived works can only be distributed under the same license terms.Repo is a tool that Google built on top of Git. Repo helps us manage the many Git repositories
Answer from Google
SQLite is an ACID-compliant embedded relational database management system contained in a relatively small (~275 kB)[4] C programming library. The source code for SQLite is in the public domain[1][5] and implements most of the SQL standard. In contrast to other databases, SQLite is not a separate process that is accessed from the client application, but an integral part of it.SQLite uses a dynamically and weakly typed SQL syntax that does not guarantee the domain integrity. SQLite is a multitasking database concerning reads. Writes can be done only one-at-a-time. It is a popular choice for local/client storage on web browsers. It has many bindings to programming languages. It is arguably the most widely used database engine, as it is used today by several widespread browsers, operating systems, embedded systems among others.[6]
Android will ship with a set of core applications including an email client, SMS program, calendar, maps, browser, contacts, and others. All applications are written using the Java programming language.:::Application Framework:::By providing an open development platform, Android offers developers the ability to build extremely rich and innovative applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more. 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.Underlying all applications is a set of services and systems, including:A rich and extensible set of Views that can be used to build an application, including lists, grids, text boxes, buttons, and even an embeddable web browserContent Providers that enable applications to access data from other applications (such as Contacts), or to share their own dataA Resource Manager, providing access to non-code resources such as localized strings, graphics, and layout filesA Notification Manager that enables all applications to display custom alerts in the status barAn Activity Manager that manages the lifecycle of applications and provides a common navigation backstack:::Libraries:::Android includes a set of C/C++ libraries used by various components of the Android system. These capabilities are exposed to developers through the Android application framework. Some of the core libraries are listed below:System C library - a BSD-derived implementation of the standard C system library (libc), tuned for embedded Linux-based devicesMedia Libraries - based on PacketVideo'sOpenCORE; the libraries support playback and recording of many popular audio and video formats, as well as static image files, including MPEG4, H.264, MP3, AAC, AMR, JPG, and PNGSurface Manager - manages access to the display subsystem and seamlessly composites 2D and 3D graphic layers from multiple applicationsLibWebCore - a modern web browser engine which powers both the Android browser and an embeddable web viewSGL - the underlying 2D graphics engine3D libraries - an implementation based on OpenGL ES 1.0 APIs; the libraries use either hardware 3D acceleration (where available) or the included, highly optimized 3D software rasterizerFreeType - bitmap and vector font renderingSQLite - a powerful and lightweight relational database engine available to all applications:::Runtime:::Android includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language.::Linux kernel:::Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack. Why Linux kernel? : Great memory and process management , permission based security model ( each android app has its own userID) , Already open source
Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently. The Dalvik VM executes files in the Dalvik Executable (.dex) format which is optimized for minimal memory footprint. The VM is register-based, and runs classes compiled by a Java language compiler that have been transformed into the .dex format by the included "dx" tool.Own instance = added security , sandboxingThe Dalvik VM relies on the Linux kernel for underlying functionality such as threading and low-level memory management.
That is, each application, by default, has access only to the components that it requires to do its work and no more. This creates a very secure environment in which an application cannot access parts of the system for which it is not given permission.

On the Java platform, a manifest file is a specific file contained within a JAR archive[1]. It is used to define extension and package related data. It is a metadata file that contains name-value pairs organized in different sections. If a JAR file is intended to be used as an executable file, the manifest file specifies the main class of the application. The manifest file is named MANIFEST.MF.
