Configuring Your DevelopmentEnvironment Android SDK compatible with Windows,Macintosh, or Linux systemsInstallation requirements for using this book:– Java Development Kit (JDK), Version 7 loads/index.html– Android Studio (includes the Android SDK) http://d.android.com/sdk/index.html

Included with Android Studio Android Studio– SDK tools– Platform tools– The latest Android platform– The latest Android system image for theemulator

Alternative Compatible Java IDE IntelliJ IDEA– Community Edition– Ultimate Edition

Alternative Configurations(Cont’d) When using other IDEs:– Command-line tools e.html– Debugging ects-cmdline.html– Testing http://d.android.com/tools/testing/testing otheride.html

Basic Installation Process1.2.3.4.5.6.Download and install the appropriate JDK.Download and install or unzip the appropriateAndroid Studio package for your OperatingSystem.Launch Android Studio and use the Android SDKManager to download and install specific Androidplatform versions and other components.Install appropriate USB drivers for devicedebugging, if necessary.Configure your device(s) for debugging.Start developing.

Basic Installation Process

Configuring Your OperatingSystem for Device Debugging To install and debug on real devices:– Configure OS to access device via USB– Mac OS May work without any configuration– Windows Requires appropriate USB driver http://d.android.com/sdk/win-usb.html– Linux Requires additional steps http://d.android.com/tools/device.html

Configuring Your OS for DeviceDebugging (Cont’d)

Configuring Android Hardware forDebugging Devices with Android 4.2 have debuggingdisabled by default.– This requires enabling Developer Options.1. From the Home screen, choose All Apps Settings About Phone (or AboutTablet).2. Scroll down to Build Number.3. Press Build Number seven times to unlockDeveloper Options.

Configuring Android Hardware forDebugging (Cont’d) To install our own applications, configure ourdevice to install from Unknown sources.1. From Home All Apps Settings Security.2. Enable (check) Unknown sources.–Skipping this step prevents us from installingour apps to our own device.
