3 Steps of Installation 0. Preparation: Enabling Intel VT-x of BIOS and/or Installing Intel HAXM 1. Installing Java Development Kit (JDK) Installing Android Studio 3. Adding SDK Packages 4. Creating Your First Application - Tools -> SDK Manager - Tools -> AVD Manager 5. Running in AVD (Android Virtual Device) * Modify the Hello Message * Import an Android Code Sample 3

4 0a. Enabling Intel HAXM (VT-x) of BIOS Hardware Accelerated Execution Manager === Logging started: 2015/3/12 23:10:54 === This computer meets the requirements for HAXM, but Intel Virtualization Technology (VT-x) is not turned on. HAXM cannot be installed until VT-x is enabled. Please refer to the Intel HAXM documentation for more information. === Logging stopped: 2015/3/12 23:11:33 === Intel HAXM: a hardware-assisted virtualization engine (hypervisor) using Intel Virtualization Technology (Intel-VT) to speed up Android app emulation Go to BIOS to turn on this support 4
