BECOMING MORE EFFECTIVE WITH THE ANDROID EMULATOR

Transcription

1 AnDevCon San Francisco 2013 PRESENTED BY LUIS DE LA ROSA DIRECTOR OF BECOMING MORE EFFECTIVE WITH THE ANDROID EMULATOR

2 AKA ANDROID EMULATOR MYTHS... BUSTED! 2.1

3 WHAT YOU WILL LEARN THE EMULATOR IS WAY, WAY BETTER THAN YOU EVER THOUGHT Engineers from many companies have been working hard on making it better...but they don t get 1 hour Broadway Launch Events to show it off.

4 WHAT YOU WILL LEARN IN DETAIL - SPEED UP THE EMULATOR - KNOW YOUR OPTIONS - BEND THE EMULATOR TO YOUR WILL

5 LET S DEMYSTIFY THIS Android Virtual Device Manager > New...

6 MYTH #1: NON-NEXUS DEVICES CAN T BE EMULATED

7 EMULATING THE AMAZON KINDLE FIRE Android SDK Manager Tools > Manage Add-On Sites... User-defined Sites, New... addon.xml

8 MYTH #1: NON-NEXUS DEVICES CAN T BE EMULATED BUSTED!

9 MYTH #1: NON-NEXUS DEVICES CAN T BE EMULATED

10 MYTH #1: NON-NEXUS DEVICES CAN T BE EMULATED

11 MYTH #1: NON-NEXUS DEVICES CAN T BE EMULATED

12 NEXUS DEVICES ARE GOOD

13 MYTH #2: EMULATOR IS SLOW STARTUP TIME ON MACBOOK PRO 2.3 GHZ I5 + SSD UPGRADE: 3:40 CONFIRMED?

14 MYTH #2: EMULATOR IS SLOW ON SUBSEQUENT STARTS: 1:10 PLAUSIBLE?

15 MYTH #2: EMULATOR IS SLOW MOST ANDROID DEVICES RUN ARM THE ANDROID EMULATOR TOO BUT ARM EMULATION ON INTEL IS SLOW

16 WHY ARM IMAGE? ACCURATE EMULATION COMPARE TO IOS SIMULATOR TRANSITION TO X86 PRESERVED ACCURACY

17 PROBLEM ARM SYSTEM IMAGE QEMU X86 CHIP

18 SOLUTION X86 SYSTEM IMAGE VIRTUAL MACHINE (HAXM) X86 CHIP WITH VT-X

19 VT-X EXPLAINED ACCELERATES X86-BASED VIRTUAL MACHINES IN HARDWARE MUST BE ENABLED IN BIOS AMD HAS SIMILAR AMD-V

20 MYTH #2: EMULATOR IS SLOW INTEL ATOM X86 SYSTEM IMAGE

21 MYTH #2: EMULATOR IS SLOW INTEL ATOM X86 SYSTEM IMAGE Available for (10), (15), (16), (17) and 4.3 (18); 4.4 is in development

22 MYTH #2: EMULATOR IS SLOW INTEL ATOM X86 SYSTEM IMAGE

23 HAXM EXPLAINED HARDWARE ACCELERATED EXECUTION MANAGER A CUSTOM VIRTUAL MACHINE FOR THE ANDROID EMULATOR

24 MYTH #2: EMULATOR IS SLOW HAXM MAKES EMULATOR RUN CLOSE TO NATIVE SPEED

25 MYTH #2: EMULATOR IS SLOW INSTALLING HAXM STEP 1

26 MYTH #2: EMULATOR IS SLOW INSTALLING HAXM STEP 2 Need to install HAXM in addition to the Android add-in. <sdk>/extras/intel/hardware_accelerated_execution_manager/ IntelHAXM.dmg (or.exe on Windows)

27 MYTH #2: EMULATOR IS SLOW INSTALLING HAXM STEP 3

28 MYTH #2: EMULATOR IS SLOW BEACON MOUNTAIN All-in-one install Includes Android SDK, Eclipse, ADT, HAXM, NDK

29 MYTH #2: EMULATOR IS SLOW ON LINUX, USE KVM INSTEAD OF HAXM emulator -avd <avd_name> -qemu -m 512 -enable-kvm

30 SOLUTION (LINUX) X86 SYSTEM IMAGE QEMU + KVM X86 CHIP WITH VT-X

31 MYTH #2: EMULATOR IS SLOW HAXM MAKES EMULATOR RUN CLOSE TO NATIVE SPEED Look in LogCat for: HAX is working and emulator runs in fast virt mode

32 MYTH #2: EMULATOR IS SLOW STARTUP TIME WITH X86 SYSTEM IMAGE + HAXM ON MACBOOK PRO 2.3 GHZ I5 + SSD UPGRADE: 0:21 BUSTED!

33 MYTH #2: EMULATOR IS SLOW ON SUBSEQUENT STARTS X86 SYSTEM IMAGE + HAXM: 0:17 DOUBLE BUSTED!!

34 MYTH #2: EMULATOR IS SLOW ON SUBSEQUENT STARTS X86 SYSTEM IMAGE + HAXM + LAUNCH FROM SNAPSHOT:

35 MYTH #2: EMULATOR IS SLOW ON SUBSEQUENT STARTS X86 SYSTEM IMAGE + HAXM + LAUNCH FROM SNAPSHOT: 0:06 TRIPLE BUSTED!!!

36 MYTH #3: DEVICES ARE BETTER FOR PROFILING HAXM/KVM LEVERAGES YOUR DESKTOP/LAPTOP CPU Intel x86 vs ARMv7 Different goals: Performance vs battery life Side-effects: Heat

37 MYTH #3: DEVICES ARE BETTER FOR PROFILING EXPERIMENTAL GPU ACCELERATION LEVERAGES YOUR VIDEO CHIPSET Note: does not play well with Snapshot

38 MYTH #3: DEVICES ARE BETTER FOR PROFILING TOO FAST? File I/O can be much slower with SD vs SSD or HDD Profiling should be done on Devices CONFIRMED

39 BRIEF MYTH INTERLUDE

40 KEYBOARD & SKIN

41 NO KEYBOARD

42 NO SKIN WITH CONTROLS

43 MEMORY & STORAGE SIZING

44 TALKING TO YOUR COMPUTER

45 KEYBOARD SHORTCUTS Rotate - Control-F11 Home - Home (Fn-left on Mac) Back - Esc Menu - F2

46 DON T SEE EMULATOR? adb kill-server adb devices (note that adb is restart implicitly)

47 MYTH #4: ANDROID EMULATOR IS LIMITED PLAUSIBLE It takes work to emulate a device and some things have not been built yet: Bluetooth USB

48 MYTH #4: ANDROID EMULATOR IS LIMITED? But it can do things that a device can t easily do. EMULATOR CONSOLE telnet localhost 5554 Note: need to enable telnet in Windows 7/8

49 MYTH #4: ANDROID EMULATOR IS LIMITED? Why 5554? EMULATOR LISTENS TO A PORT > adb devices List of devices attached emulator-5554 device

50 MYTH #4: ANDROID EMULATOR IS LIMITED? INBOUND CALL gsm call

51 MYTH #4: ANDROID EMULATOR IS LIMITED? INBOUND SMS sms send "It's me, Jenny"

52 MYTH #4: ANDROID EMULATOR IS LIMITED? ENABLING POWER CHANGES In <avd_home>/avd/<avd_name>.avd/config.ini: change hw.battery=no to hw.battery=yes Otherwise: crash!

53 MYTH #4: ANDROID EMULATOR IS LIMITED? ENABLING POWER CHANGES

54 MYTH #4: ANDROID EMULATOR IS LIMITED? No support for determining battery charge level and AC charging state. - Android Emulator Documentation BUSTED!

55 MYTH #4: ANDROID EMULATOR IS LIMITED? FULL SPEED AHEAD! power capacity 100 power ac on

56 MYTH #4: ANDROID EMULATOR IS LIMITED? ALMOST EMPTY power ac off power status discharging power capacity 10

57 MYTH #4: ANDROID EMULATOR IS LIMITED? SAY CHEESE!

58 MYTH #4: ANDROID EMULATOR IS LIMITED? EMULATED CHEESE

59 MYTH #4: ANDROID EMULATOR IS LIMITED Experimental tethering support for: Hardware Sensors Multi-Touch

60 MYTH #5: DEVICE IS BETTER FOR DEBUGGING BUSTED Emulator is like a Rooted Device without voiding your warranty

61 MYTH #5: DEVICE IS BETTER FOR DEBUGGING You can t normally browse internal data at /data/data

62 MYTH #5: DEVICE IS BETTER FOR DEBUGGING You can pull a file and verify

63 MYTH #5: DEVICE IS BETTER FOR DEBUGGING Unit Tests run faster on Emulator (due to CPU) Can click with mouse instead of touching Your physical keyboard is easier to use than virtual

64 MYTH #5: DEVICE IS BETTER FOR DEBUGGING Sometimes you don t have a device On the plane Left it at home Presentation The Next Big Thing

65 MYTH #5: DEVICE IS BETTER FOR DEBUGGING The Next Big Thing

66 MYTH #5: DEVICE IS BETTER FOR DEBUGGING The Next Big Thing

67 MYTH #5: DEVICE IS BETTER FOR DEBUGGING The Next Big Thing

68 MYTH #5: DEVICE IS BETTER FOR DEBUGGING The Next Big Thing

69 BREAKING NEWS: GENYMOTION Commercial alternative to existing emulator options Released yesterday (11/13/2013) Built on the open source project AndroVM Runs on both Intel s VT-x and AMD s AMD-V May be the future of Android emulation

70 GENYMOTION: USES VIRTUALBOX Like HAXM, but different. Don t try to use both at the same time.

71 SOLUTION (GENYMOTION) X86 SYSTEM IMAGE VIRTUAL MACHINE (VIRTUALBOX) X86 CHIP WITH VT-X

72 GENYMOTION LETS YOU SKIP THE AVD CONFIGURATION SCREEN

73 GENYMOTION ADDS VISUAL CONTROLS

74 GENYMOTION SHELL: THE ALTERNATIVE TO EMULATOR CONSOLE

75 WHICH TO USE? TRY BOTH HAXM AND GENYMOTION
