client.openProcStat(serial[, callback]) Android 7

[anaraquelazevedo]

I´m having a problem accessing the data in some mobiles models, with android 7 (for instance, nexus 6). With android 7 i cannot access the system files, proc/stat for example, and since adbkit´s method client.openProcStat(serial[, callback]) tries to read that data. I can´t garantee an appropriate error handling while acessing that data and i get this error:

Unhandled rejection FailError: Failure: open failed: Permission denied'

Can anyone shoot any ideas? or new aproaches to this problem!? Thanx in advance!

Run adb shell cat /proc/stat. If that gives you permission denied, then there isn't anything we can do about it. You could possibly use dumpsys with .shell() to access similar information.

with adb shell cat /proc/stat i have permission to access file!
How can I make this method (OpenProcStat) for all phones with adb shell?

Hmmm that's weird... what's the model? Run adb devices -l and paste the line here (you can remove the serial number though if you like).

Hi,
got the same problem that openProcStat fails with permission denied, while I can access proc/stat without any problems.
