debugging - Android studio 2.3 "Debug shows Connected and Disconnected lines but nothing in between"

Question

I'm testing my app in a physical device

On debug run

    Console 

$ adb push C:UsersarjunAndroidStudioProjectsScolappuildoutputsapkapp-debug.apk /data/local/tmp/com.example.arjun.scol
$ adb shell pm install -r "/data/local/tmp/com.example.arjun.scol"
    pkg: /data/local/tmp/com.example.arjun.scol

Success


$ adb shell am start -n "com.example.arjun.scol/com.example.arjun.scol.login.Login" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER -D

Waiting for application to come online: com.example.arjun.scol | com.example.arjun.scol.test
Waiting for application to come online: com.example.arjun.scol | com.example.arjun.scol.test

Connecting to com.example.arjun.scol
Connected to the target VM, address: 'localhost:8600', transport: 'socket'
Disconnected from the target VM, address: 'localhost:8600', transport: 'socket'

My app crashes due to error, but nothing is displayed in the debug console... this happened after updating android studio to 2.3..

But when I scroll through Android Monitor,I found the error messages

I had edited the run configuration too...but that didn't help...

Should i downgrade android studio?

Answer 1

Go to Run -> Edit Configurations

Second tab "Miscellaneous"

Check item "Show logcat automatically"

it's better to check item "Clear log before launch", too.

and see logs and crashes in Android Monitor logcat
