Designing For Android Emulator The Android SDK includes a mobile device emulator — a virtual mobile device that runs on your computer. The emulator lets you develop and test Android applications without using a physical device. This document is a reference to the available command line options and the keyboard mapping to device keys. For a complete guide to using the Android Emulator, see Using the Android Emulator. Keyboard Commands Table 1 summarizes the mappings between the emulator keys and the keys of your keyboard. Table 1. Command Line Parameters The emulator supports a variety of options that you can specify when launching the emulator, to control its appearance or behavior. emulator -avd <avd_name> [-<option> [<value>]] ...

android - getSize() giving me errors Samsung Galaxy Tab Características[editar] Rendimiento[editar] En cuanto hablamos de rendimiento, hay que recordar que este tablet fue el primero en plantar cara y mejorar el iPad de Apple; a diferencia de éste, Samsung opto por mejorar ligeramente las características del Galaxy S para luego implantarlas en un dispositivo de 7", del potente procesador de 1 GHz del Galaxy S, el Galaxy Tab cuenta con uno con la misma arquitectura ARM Cortex y el mismo Soc Hummingbird pero con 1,2 GHz; también hay que hablar de la tarjeta gráfica, aunque ésta apenas haya sido mejorada de los 200 MHz PowerVGR-540 del Galaxy S a los 220 MHz del mismo tipo de procesamiento gráfico del Galaxy Tab Sistema operativo[editar] El sistema operativo original de este dispositivo es Android 2.2.1, actualizado de forma automática a 2.3.5. Muchos usuarios han podido actualizarla mediante Samsung Kies pocos meses después de que se pudiera comprar en tiendas.

<uses-sdk> Google Play Filtering Google Play uses the <uses-sdk> attributes declared in your app manifest to filter your app from devices that do not meet it's platform version requirements. Before setting these attributes, make sure that you understand Google Play filters. syntax: contained in: description: Lets you express an application's compatibility with one or more versions of the Android platform, by means of an API Level integer. Despite its name, this element is used to specify the API Level, not the version number of the SDK (software development kit) or Android platform. Also read the document about Versioning Your Applications. attributes: android:minSdkVersion An integer designating the minimum API Level required for the application to run. Caution: If you do not declare this attribute, the system assumes a default value of "1", which indicates that your application is compatible with all versions of Android. android:targetSdkVersion Introduced in: API Level 4 android:maxSdkVersion API Level 1
Android UI Design Kit PSD 4.2 [Free Download] | Android User Interface | User Experience In August 2012, Android ICS/JB Photoshop GUI Design Kit 3.0 was published with some new Jelly Bean UI elements, and until today, the Design Kit has been downloaded over 21,000 times since the very first version back in December 2011 – not a huge number, but it is putting a smile on my face. It’s really nice to see there are many designers interested in Android Design and used the Design Kit to kick-start their design work in Android app. A big thank you to everyone that is using the design kit and I really hope it helps in your Android app design workflow in some way. And today, I have finally updated the Android UI Design Kit PSD to version 4.2, with the size of Nexus 4 screen resolution (768×1280), as requested by many supporters. Besides the resolution update, I have also added a few new UI elements into the Design Kit: Cards (Google Now)CroutonDrawer MenuQuick ReturnUndo BarGestures Android UI Design Kit 4.3 for Photoshop and GIMP is here!

Design - Metrics and Grids Devices vary not only in physical size, but also in screen density (DPI). To simplify the way you design for multiple screens, think of each device as falling into a particular size bucket and density bucket: The size buckets are handset (smaller than 600dp) and tablet (larger than or equal 600dp). Optimize your application's UI by designing alternative layouts for some of the different size buckets, and provide alternative bitmap images for different density buckets. Because it's important that you design and implement your layouts for multiple densities, the guidelines below and throught the documentation refer to layout dimensions with dp measurements instead of pixels. Space considerations Devices vary in the amount of density-independent pixels (dp) they can display. To see more, visit the Screen Sizes and Densities Device Dashboard. 48dp Rhythm Touchable UI components are generally laid out along 48dp units. Why 48dp? Mind the gaps Spacing between each UI element is 8dp. Examples
xamarin/monodroid-samples android - Create a fixed menu bar Android UI Design Patterns: Tablet UI Patterns Android Action Bar is a well established UI pattern on Android phone UI design. It is the single most powerful visual tool to make an app look like an Android app. In their tablet version of the Android OS Google decided to support the pattern on API level. In Honeycomb implementing a standard looking Action Bar is easier than ever before. Most important app functionality should always be easily accessible by users. Apps on a single platform should be internally consistent how they approach main level navigation and important actions. Action bar is a branded top bar of the application that provides easy access to relevant actions on the screen and a shortcut to application's home screen. Very easy and fast access to relevant action on current screen.Easy access to application's home screen by clicking the application logo at left.

Hello, Multiscreen Applications In this article we’ll look at how to create multi-screen applications using Xamarin.Android and walk through the creation of a simple multi-screen app. We’ll introduce Intents and show how they can be used to load additional Activities. However, before we dive into creating the application, let’s examine the constituent pieces of an Android application. Android applications are very different from traditional client applications found on platforms such as Windows, Mac OS X and even mobile platforms such as iOS. These platforms have a single entry point into the application in the form of a static main function, which creates an instance of an application that then launches, loads and manages its screens, etc. The following diagram illustrates the components of a basic Android application: This loosely coupled architecture presents an interesting problem for multi-screen applications. Let’s explore Activities and Intents a little more. Activities Context Activity Lifecycle Overview Intents
Iconography An icon is a graphic that takes up a small portion of screen real estate and provides a quick, intuitive representation of an action, a status, or an app. When you design icons for your app, it's important to keep in mind that your app may be installed on a variety of devices that offer a range of pixel densities, as mentioned in Devices and Displays. But you can make your icons look great on all devices by providing each icon in multiple sizes. When your app runs, Android checks the characteristics of the device screen and loads the appropriate density-specific assets for your app. Because you will deliver each icon in multiple sizes to support different densities, the design guidelines below refer to the icon dimensions in dp units, which are based on the pixel dimensions of a medium-density (MDPI) screen. Launcher The launcher icon is the visual representation of your app on the Home or All Apps screen. Sizes & scale Launcher icons on a mobile device must be 48x48 dp. Proportions Style
Hello, Android In this article we’ll look at how to create, deploy, and run a Xamarin.Android application. First, we’ll demonstrate how to use the default application template in the deployment process. Next, we’ll examine some of the basic parts of the android application that are created with the template. To get started, we are going to walk through the steps you need to take to create a Xamarin.Android application. Creating a New Application Let’s begin by creating a new Xamarin.Android solution. Android Library Project – A reusable .NET library project for Android. We’re going to use the Android Application template for this walkthrough.
