Android developer tools and android sdk tools to facilitate testing for QA engineers.

1. Android developer options &
Android SDK tools
(for QA)

2. Agenda
1. Overview of the “android developer tools”
2. Overview of the “android sdk tools”
3. Developer tools - top list features
4. Short overview of tools & libs used by Good&Co android developers

3. Developer options - How to install*
1. Go to the settings menu, scroll down to “About phone” and tap it.
2. Scroll down to the bottom again, where you see “Build number”
3. Tap it seven times. After the third tap, you will see a dialog that says: “you’re four
taps away from being a developer”. Keep on tapping until you have got your
special setting appear.
Note: it’s hidden by default starting from android 4. 2

4. Android developer options structure
● Debugging options
● Input options
● Drawing / hardware accelerated rendering options
● Monitoring options
● Apps options

5. Debugging options
1. “USB debugging” - connecting device via usb.
2. “Take bug report / Bug report option” - collection info with logs about device state with
sending e-mail message.
3. “Desktop backup password” - allows to use ADB to backup and restore things like apps and their
associated data to and from your computer
4. “Stay awake / Always stay awake” - screen will never sleep while charging
5. “HDCP checking” - protecting files, which are shared via Wi-Fi, Bluetooth, etc.
6. “Enable Bluetooth HCI snoop log” - logging every transmitted file via bluetooth
7. “Process Stats” - monitoring app usage statistics
8. “Allow Mock Location” - forcing user location using GPS and 3-rd party resources
9. “Select debug app” - setting lets you choose an application to debug.

6. Debugging options
10. “Verify apps via USB” - lets Android scan applications you installed via ADB for malicious behavior.
11. “Enable Wi-Fi verbose logging” - logging more information as usual (slows down device
performance)
12. “Wi-Fi to Cellular handover“- appropriate switching to wi-fi mode in case of slow cellular
connection and back again

7. Input options
13. “Show touches” - displaying finger touches on the display (useful while screen-recording)
14. “Pointer Location” - this setting places an information bar at the top of your screen telling you the
screen coordinates of the last place the screen was touched.

9. Drawing options
15. “Surface update” - makes the edge of a "window" flash when its contents are updated.
16. “Show layout bounds” - marks the edges of all the elements in a dialog so you know where any touch
will activate them.
17. “Force RTL direction” - forces screen orientation for right to left language support.
18. “Window animation scale” - sets the speed for window animation. A lower number is faster.
19. “Simulate secondary displays” - this setting allows us to simulate different screen sizes.

11. Drawing / Hardware accelerated rendering options
20. “Show hardware layers updates” - displaying screen flashes when device updates surface (useful
when developing widgets)
21. “Debug GPU overdraw” - overdraw happens every time the application asks the system to draw
something on top of something else. This setting lets you see when and where this is happening so you know if
it is a problem.

12. Monitoring options
22. “Strict mode enabled” - this setting flashes the screen when an application uses the main thread to
perform long, intensive operations.
23. “Show CPU usage” - places a window in the upper right of your screen with information about the
CPU and how it is being used

13. Apps options
24. “Don’t keep activities” - destroys every activity as the user leaves it (if enabled, going to background
will destroy current app activity, if disabled - app will run in background) - In other words Android will destroy
and activity as soon as it’s stopped. We can simulate the case that Android will kill an activity in the background
due to memory pressure
25. “Background process limit” - limiting number of process which can run in background (may be
useful when testing apps on slow devices)
26. “Show all ANRs” - displays all “application not responding” dialogs while using the device

14. Allow mock location option (How to set)
1. Enable “Allow mock location” option in developer options
2. Install app like “Fake GPS location” or similar
3. In the installed app set desired location
4. Use your mocked location in browser web-site or in app

15. Android SDK tools
- Android Device Monitor:
- DDMS - tool to debug android applications
- Hierarchy Viewer - detailed displaying of app views, layouts
- PixelPerfect - comparing implemented app design with target design
- Retrieving data from device (SQL, SharedPreferences)
- Using AdbRun
- UiAutomatorViewer
- Displaying application view, layouts with resource identifiers
- Android Monkey
- Simple automation tool for light smoke run (useful to increase crash-free users)

19. ADB commands
- adb install C:package.apk – Installs the package located at C:package.apk on your computer on your
device.
- adb uninstall package.name – Uninstalls the package with package.name from your device.
- adb push C:file /sdcard/file – Pushes a file from your computer to your device. For example, the
command here pushes the file located at C:file on your computer to /sdcard/file on your device
- adb pull /sdcard/file C:file – Pulls a file from your device to your computer – works like adb push, but in
reverse.
- adb logcat - views android device logs
- Running scripts

20. Android monkey - basic usage
- adb shell monkey [options] <event-count>
- adb shell monkey -p your.package.name -v 500
- --help - prints a simple usage guide.
- --throttle <milliseconds> - inserts a fixed delay between events. You can use this
option to slow down the Monkey
- -p <allowed-package-name> - if you specify one or more packages this way, the
Monkey will only allow the system to visit activities within those packages.

21. Other interesting tools
- “Spare parts” and it’s possibilities:
- Enable/Disable compatibility mode to allow Apps to work at full screen size on Galaxy Tab and other large screen devices
- Control windows animation speeds or disable them entirely to speed up your device!
- No annoying AdMob adverts

22. Developer options - top list features
● Allow mock locations
● Don’t keep activities
● Show layout bounds
● Show touches

23. Short overview of tools & libs used by Good&Co android developers

2. DDMS
3. Cobertura - tool for Code Coverage
