I am running my app in debug mode. But it is not showing the Logcat.
The logcat is working and prints lots of rubbish. At the top next to the device connected it says. No Debuggable Application. how came ?

I finally found a solution by: @nick-unuchek - Than you
Android Studio doesn't display logs by package name
Logs wasn't display because my app doesn't display in process.
So finally I got it working, by: Click on
enter image description here
Checking 'Show all processes' checkbox!
BUT as you see in the question, checkbox was on at the beginning, so there were multiple issues.
To summarize, these are other actions to be done:
Kill all adb processes (use ps -x | grep adb and kill -9 ****) adb start-server in terminal Reconnect device adb device (to make sure device is connected successfully) Make sure Android DDMS Devices | logcat shows your app and only one device is listed. Check Show all processes checkbox

Go to your build.gradle and set debuggable true on the build type you want. That should fix it
