Answer 3

Answer to your question #2 You can inspect Android app directly from your real Android device.

You need to:

• Connect Android device to your computer/laptop
• Go to Android device Settings -> Enable Developer Options and Android debbuging

Please see here:

• Start the app you wish to inspect in your Android device

• Open up the Chrome browser on your computer/laptop and do a right click -> More Tools -> Inspect devices -> Click on your device -> (Click on Android device OK to authorize) -> Click Inspect

Please see here:

That's it. Hope it helps!

Answer 4

1) stop appium Server

2) open an emulator device

3) go into settings > developer options > Enable view attribute inspection

4) developer options in invisible? Go into settings > Tap on About device/phone > Scroll down till the last option(Build number) > Continuously Tap on "Build number" for 7 times > you should get an Toast message "You're a developer" > come back from that screen > Go back into settings > Now you should see developer options Tap on it > Enable view attribute inspection

5) You should no more get this error message

Answer 5

What worked for me:

stop appium
open an emulator device (tested with Android 7.1.1)
go into settings > developer options > Enable view attribute inspection
open a shell on the computer, cmd or terminal depending on your OS
enter the following commands:
adb shell
su
cd /data
cd /local
chmod 777 tmp

start uiautomatorviewer
take an xml screenshot

"su chmod 777 /data/local/tmp" didnt work for me so I drilled down and it worked.
I assume that you have to do this in an emulator and not a physical device unless the device is rooted. ¯ \ _ (ツ)_/¯

Lotsa Luck!

Answer 6

Check whether you have enabled these under "developer options" in the phone.

1. Verify apps via USB
2. View attribute inspection
3. USB debugging
