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>]] ...

Using the Android EmulatorThe Android SDK includes a virtual mobile device emulator that runs on your computer. The emulator lets you prototype, develop and test Android applications without using a physical device. The Android emulator mimics all of the hardware and software features of a typical mobile device, except that it cannot place actual phone calls. To let you model and test your application more easily, the emulator utilizes Android Virtual Device (AVD) configurations. The emulator also includes a variety of debug capabilities, such as a console from which you can log kernel output, simulate application interrupts (such as arriving SMS messages or phone calls), and simulate latency effects and dropouts on the data network. Overview The Android emulator is an application that provides a virtual mobile device on which you can run your Android applications. The Android emulator supports many hardware features likely to be found on mobile devices, including: Android Virtual Devices and the Emulator
JDK 7 Support in the Android SDK? - Google GroupesI am still catching up with the Google I|O conference videos. I just watched the Android Fireside Chat one. The question came up regarding JDK 7 support, and, if I understood correctly, Xav indicated that such support already existed, as of R21 (or R21.0.2 or something like that -- tough to hear that bit when watching the video on a plane...). Did I understand that correctly? If yes, are there any SDK/ADT-specific instructions for getting this to work? Is this something you want people using? Thanks!Java Archive Downloads - Java SE 6Go to the Oracle Java Archive page. Thank you for downloading this release of the JavaTM Platform, Standard Edition Development Kit (JDKTM).

Telnet BBS Guide - Main PageWhat Is Telnet & What Are Its Uses? [MakeUseOf Explains]Telnet is one of those tech terms you may occasionally hear, but not in an ad or a feature laundry list of any product you may buy. That’s because it’s a protocol, or a language used to talk to computers and other machines; not only that, but Telnet is actually ancient in Internet terms, dating back from 1973. So what is Telnet, and what is it good for, anyway? A Concise Definition Wikipedia’s terse definition of Telnet is: Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communications facility using a virtual terminal connection. Wow, that’s a mouthful. Network protocol: That’s basically a language, a way for machines to talk to one another.Bidirectional: That means Telnet is not one-way; it can be used to send and receive information.Interactive: That means Telnet basically expects a live user on one end of the line. Now that we have gone over these, go back and read the Wikipedia definition again.

Creative VisionWe focused the design of Android around three overarching goals, which apply to our core apps as well as the system at large. As you design apps to work with Android, consider these goals: Enchant me, Simplify my life, and Make me amazing Enchant me Beauty is more than skin deep. Simplify my life Android apps make life easier and are easy to understand. Make me amazing It's not enough to make an app that is easy to use.Design PrinciplesThese design principles were developed by and for the Android User Experience Team to keep users' best interests in mind. For Android developers and designers, they continue to underlie the more detailed design guidelines for different types of devices. Consider these principles as you apply your own creativity and design thinking. Deviate with purpose. Enchant Me Delight me in surprising ways A beautiful surface, a carefully-placed animation, or a well-timed sound effect is a joy to experience. Real objects are more fun than buttons and menus Allow people to directly touch and manipulate objects in your app. Let me make it mine People love to add personal touches because it helps them feel at home and in control. Get to know me Learn peoples' preferences over time. Simplify My Life Keep it brief Use short phrases with simple words. Pictures are faster than words Consider using pictures to explain ideas. Decide for me but let me have the final say Only show what I need when I need it
