Application Fundamentals
Android apps are written in the Java programming language. The Android SDK tools compile your code—along with any data and resource files—into an APK: an Android package, which is an archive file with an .apk suffix. One APK file contains all the contents of an Android app and is the file that Android-powered devices use to install the app. Once installed on a device, each Android app lives in its own security sandbox: The Android operating system is a multi-user Linux system in which each app is a different user. By default, the system assigns each app a unique Linux user ID (the ID is used only by the system and is unknown to the app). In this way, the Android system implements the principle of least privilege. However, there are ways for an app to share data with other apps and for an app to access system services: It's possible to arrange for two apps to share the same Linux user ID, in which case they are able to access each other's files.

Upside-Down-TernetHowTo Note: This guide was tested using Ubuntu 8.10. Previous versions may not work. This is a HowTo for setting up Upside-Down-Ternet on Ubuntu. Basically, when a user browses the web, all the images are flipped upside-down. While it's not useful, it's quite a good April Fool's prank. The process uses a transparent proxy, web server, and script to flip the images. Android SDK Development & Programming This example explains how we can convert latitude longitude values to corresponding address. The process is called Reverse geocoding. Algorithm: 1.) Create a new project by File-> New -> Android Project name it Gecoding-example. 2.) You will see some default code into your main.xml and android manifest file. 3.)

Settings Class Overview The Settings provider contains global system-level device preferences. Summary Constants Upside-Down-Ternet My neighbours are stealing my wireless internet access. I could encrypt it or alternately I could have fun. I'm starting here by splitting the network into two parts, the trusted half and the untrusted half. The trusted half has one netblock, the untrusted a different netblock. We use the DHCP server to identify mac addresses to give out the relevant addresses. Android SDK: Working with Google Maps – Application Setup The Google Maps API for Android provides developers with the means to create apps with localization functionality. Version 2 of the Maps API was released at the end of 2012 and it introduced a range of new features including 3D, improved caching, and vector tiles. In this tutorial series, we will create an app that uses Google Maps for Android V2 in conjunction with the Google Places API. The app will present a map to the user, mark their current location and nearby places of interest, and will update when the user moves. This tutorial series about Using Google Maps and Google Places in Android apps will be presented in four parts:
