  HOW TO ACCESSALL THESE FUNCTIONS
• 12.
  ANDROID STUDIO • AndroidStudio is the official integrated development environment (IDE) for Android application development. • It is based on the IntelliJ IDEA, a Java integrated development environment for software, and incorporates its code editing and developer tools.
• 13.
  FEATURES ANDROID STUDIO • Code writtenin Java and Kotlin. • Having intelligent code editor for code completion • It provide tools to write our code and lay out of the app on screen. • Provides real time Preview as we create an app. • Gives error correction and suggestion for code. • The created app is tested on real device or Android Studio Emulator for simulation.
• 14.
  Android Emulator • TheAndroid 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. AVD Manager • The AVD Manager provides a graphical user interface in which you can create and manage Android Virtual Devices (AVDs), which are required by the Android Emulator. Optional Installation - Genymotion • It is a fast third-party Android emulator for app testing and presentation on Windows that can be used instead of the default Android emulator. In some cases, it's as good as or better than developing on actual devices! IMPORTANT TOOLS

  INSTALLATION • Java 1. Visithttp://www.oracle.com/technetwork/java/javase/downloads/index.html 2. Install it. • Android Studio 3. Visit http://developer.android.com/sdk/index.html 4. click the button Download Android Studio. 5. Accept terms, and click Download. 6. Run executable file of setup. 7. Follow the setup wizard to install Android Studio and any necessary SDK tools. 8. On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location. 9. Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:Program FilesJavajdk1.7.0_45

  10. The individualtools and other SDK packages are saved outside the Android Studio application directory. If you need to access the tools directly, use a terminal to navigate to the location where they are installed. For example: 11. Users<user>sdk 12. Android Studio is now ready and loaded with the Android developer tools, but there are still a couple packages you should add to make your Android SDK complete. • Run 1. Run Android Studio as Administrator. 2. Before you create new project, click Configure from splash screen. Click SDK Manager. 3. Don’t select all. In bottom, in Extra section, select Intel x86 Emulator Accelerator. 4. Click Install button. INSTALLATION CONT:

  ANDROID APP FILES •Java: Java class files containing app logic • Res: Different resource files • Anim: Animation resource files • Drawable: Images • Drawable-Xdpi: Images depending on screen density • Layout: App layout files • Menu: Layout menu files • Values: Value files (strings, colors, arrays, etc) • Values-vX: Value files depending on API level • Values-Xdp: Value files depending on screen density • XML: XML files (duh) • AndroidManifest.xml: App metadata file • build.gradle: Build related settings
• 22.
  DEPLOYING THE APP • Twochoices for deployment: • Real Android device • Android virtual device • Plug in your real device; otherwise, create an Android virtual device • Emulator is slow. Try Intel accelerated version, or perhaps http://www.genymotion.com/ • Run the app: press “Run” button in toolbar
