ADB Logcat 什么都不显示

Question

I'm having trouble with ADB Logcat.

What I did: (in my android device, I'm using LG G6):

• turned USB debugging on
• connected the device to the computer

(in my computer)

• used windows powershell
• cd AppData\\Local\\Android\\android-sdk\\platform-tools

I did .\\adb devices and the output is List of devices attached LGH870DSe2cfa712 device

I did .\\adb logcat -s Unity ActivityManager PackageManager dalvikvm DEBUG and it showed nothing. It worked normally a few days ago.

when I disconnected the device, the adb automatically stopped the logcat. I tried doing adb when no devices are connected and it showed -waiting for devices- , then I connected the device and nohthing happened.

I then tried another device (Asus Zenfone 3 max) and the powershell showed this:

PS C:\Users\user\AppData\Local\Android\android-sdk\platform-tools> .\adb logcat -s Unity ActivityManager PackageManager
dalvikvm DEBUG

Answer 1

What is you adb version and LG G6 version?

adb 1.0.39 work well with LG G6 (android7) if you need adb logcat .

adb 1.0.40 and 1.0.41 unable work with LG G6 (android7) .

Answer 2

Here is something I noticed.

I have a couple of devices that shows nothing when I run adb logcat , but logcat works if I see the log in Android Studio. When that happens, I run adb shell -t logcat , which seems to work.
