Using adb logcat with a real phone (and not the emulator)
when I'm using the Android emulator I can do "adb logcat" to see output messages (log / system.out.println) originated from my code. It also shows the stack trace of exceptions which happen during execution.
But, when I'm using a real phone, "adb logcat" does not do / show anything.
I also tried "adb -d logcat" which also does not display anything.
Is there any way to get it working with the real phone?
Thanks.
UPDATE:
I just tried "adb -s ? logcat" ('?' is the serial number of the device) and also got no results.
I tried another "adb" command to see if anything was working: "adb -s ? bugreport". This printed a lot of stuff. Example: "Memory Info", "CPU Info" and some Java specific things. So it seams that some stuff is working.
Answer
Enable USB debugging in your device.
Connect device to computer
Use this commands
--> $adb devices (will give the "device id" that is connected) output ex. 82990AB830201D device
--> $adb -s "device id" logcat (you will be able to see your device logcat)
ex $adb -s 82990AB830201D logcat
I follow this steps and it works good.
