LogCat Missing from Android Studio 3.1.3
You need to sync your project and then Logcat will show up
I know it is an old question, but I encountered this problem at least twice so it might help someone.
The problem seems to be the path of the project you're looking at. It should be pointing to the folder containing the 'app' and 'gradle' folders inside your project.
- Go to File > Open
- Select the folder with the 'app' folder inside your project
- Press 'Open'
If you see something like this you can now probably open the Logcat window with alt-6 or View->Tool Windows.
Note that for some reason, it didn't work for me at first until I opened the app folder, run a build and then opened the folder containing the app folder.
Just in case anyone stumbles upon this as I did: If you are developing a react-native app, be sure that you import only the android folder of the project.
If you import the whole project, then among other things, logcat is nowhere to be found!
