Logcat tab missing from debug window in Android Studio
In Android Monitor
window, click the little tiny button on the top right corner.
I think with the release of Android Studio 1.4 the logcat tab has been removed from the Debug view. Now I believe the only place to access it is by opening the Android Monitor
view by pressing Alt+6 on Windows or CMD+6 on Mac.
Release notes of Android Studio 1.4 Beta 3 allude to this:
Logcat view mostly rewritten to address a number of stability and usability bugs
