Android (operating system) Free and open-source operating system for mobile devices, developed by Google Android is a mobile operating system developed by Google. It is based on a modified version of the Linux kernel and other open source software, and is designed primarily for touchscreen mobile devices such as smartphones and tablets. In addition, Google has further developed Android TV for televisions, Android Auto for cars, and Wear OS for wrist watches, each with a specialized user interface. Initially developed by Android Inc., which Google bought in 2005, Android was unveiled in 2007, with the first commercial Android device launched in September 2008.

Choosing a Dissertation Topic Choosing the right topic is crucial. The topic you choose will be with you for a while, maybe even for life! Create It; Don't Find It Well, your topic is not going to come to you in the wilderness or in the library. Is It the Right One? The criteria I use to evaluate a topic are: Is it YOU? Autoriser la synchronisation uniquement en WiFi - Android A chaque fois que votre téléphone sous Android synchronise vos comptes : Gmail, Facebook, Twitter, …, il se connecte à Internet pour télécharger des données. Si votre forfait Internet n'est pas illimité ou que vous êtes à l'étranger, la facture peut vite grimper. Si Android vous permet de bloquer la synchronisation automatique, vous devrez alors la lancer manuellement à chaque fois que vous voudrez mettre à jour vos informations. Avec l'application AutoSync, la synchronisation se fait automatiquement lorsque vous êtes connecté à Internet en WiFi.

Android Developers Blog Web Apps Figure 1. You can make your web content available to users in two ways: in a traditional web browser and in an Android application, by including a WebView in the layout. There are essentially two ways to deliver an application on Android: as a client-side application (developed using the Android SDK and installed on user devices in an APK) or as a web application (developed using web standards and accessed through a web browser—there's nothing to install on user devices). If you chose to provide a web-based app for Android-powered devices, you can rest assured that major web browsers for Android (and the WebView framework) allow you to specify viewport and style properties that make your web pages appear at the proper size and scale on all screen configurations. Figure 1 illustrates how you can provide access to your web pages from either a web browser or your your own Android app. To start developing web pages for Android-powered devices, see the following documents:

Install the GNU ARM toolchain under Linux If you are interested in embedded systems development on a widely used microprocessor, the Advanced RISC Machines (ARM) core fits the bill. This article provides a starting point for understanding the software side of embedded systems development by describing one set of commonly used tools: the GNU ARM toolchain. The ARM family Paramount among the concerns of embedded systems developers is how to get the most processing power from the least amount of electricity. The ARM core has gained technology advances through several versions over the last 20 years. The more recent ARM cores support two operational states: ARM state, in which the core executes 32-bit, word-aligned instructions, and THUMB state, which executes 16-bit, halfword-aligned instructions. ARM processors improve performance by taking advantage of a modified Harvard architecture.

Android download categories Best Practices Android is designed to run on many different types of devices, from phones to tablets and televisions. As a developer, the range of devices provides a huge potential audience for your app. In order for your app to be successful on all these devices, it should tolerate some feature variability and provide a flexible user interface that adapts to different screen configurations. To facilitate your effort toward that goal, Android provides a dynamic app framework in which you can provide configuration-specific app resources in static files (such as different XML layouts for different screen sizes). If necessary, however, you can specify your app's feature requirements and control which types of devices can install your app from Google Play Store. What Does "Compatibility" Mean? As you read more about Android development, you'll probably encounter the term "compatibility" in various situations. Controlling Your App's Availability to Devices Device features Platform version Screen configuration
