adb error: couldn't create file: Permission denied

AlexandraMoga commented 1 year ago

Original report - https://github.com/mozilla/geckodriver/issues/2092; please check comments there for additional logs

System

geckodriver Version: v0.32.2-win32
Platform: Windows 10
Firefox: Firefox Nightly 112.0a1 (Build #2015933405),
Appium: v2.0.0-beta.56 (Python client)

Testcase

I'm simply traying to launch Firefox on an android device (Pixel 5, Android 11 emulator with Android studio) using the capabilities suggested in this documentation but the session hangs and finally exists with error adb error: couldn't create file: Permission denied. I'm not sure if there is some issue at my side (capabilities are visible in the stacktrace) or if this is a geckodriver issue.

As you can see there the error os coming from geckodriver itself. You could assign the verbosity capability to trace in order to see more detailed geckodriver output and attach the resulting log here

mykola-mokhnach commented 1 year ago

also I can observe this error in the linked issue report:

[debug] [GeckoDriver@03b7 (1d39ac55)] 1677837573945 mozdevice TRACE execute_host_command: >> "shell:su 0 chmod -R 777 /sdcard/Android/data/org.mozilla.fenix/files/test_root/org.mozilla.fenix-geckodriver-profile"

have you tried to run it manually from the terminal? what was the output?

AlexandraMoga commented 1 year ago

So, if I run adb shell "su 0 chmod -R 777 /sdcard/Android/data/org.mozilla.fenix/files/test_root/org.mozilla.fenix-geckodriver-profile" from the terminal I receive a No such file or directory response. If I check the emulator file system, I can see that these files don't exist on the sdcard. Also, given the fact that the emulator is rooted, shouldn't internal storage take precedence when a new file is created? I am a bit confused why the program chooses the external storage.

mykola-mokhnach commented 1 year ago

I don't know. I assume there might be some bug in the geckodriver itself, so it verifies folder existence first or runs mkdir -p before running chmod

You could probably also play with appium:androidStorage capability value
