Logcat doesn't work in android studio

I use android studio 0.4.2 and logcat does not work (its just empty). USB debugging is enabled, filters are disabled and log level is verbose. Any ideas?

Clear the log before launch

App -> EditConfigurations -> Miscellaneous -> Clear log before launch

In case you make it down here, @Maarten's comment above worked for me. Close Android Studio then adb devices at Ubuntu terminal:

ewan@xxxx:~/AndroidStudioProjects/projectx$ adb devices List of devices attached adb server version (41) doesn't match this client (39); killing... * daemon started successfully FA7Bxxxxxx2 device

Restarted Android Studio and logcat window worked again.

UPDATE: d'oh I found that I was inadvertently using version 39 from the terminal window whereas Android Studio was using 41

In my case, I had two Android phones plugged in for debugging. Switching phones, using the drop down box, didn't do a thing, so I:

-unplugged both

-restarted Android Studio (and the project)

-plugged in the (one) device for which I wanted to see the logs

That did it for me. Logs were back ... now just to fix the code.

On your android monitor:

Restart your LogCat.
Set no filters because Android studio 2.2 has Firebase.
Clear your searching filter.
Select your running device.

If not work clear Android studio caches. File->invalidate caches/restart

When apply all way but still not working then use Android device monitor. Tools -> Android -> Android device monitor.

To add to this thread of solutions,

Check for if you have multiple devices connected. Than select the device that you want logs from (upper left corner on logcat window). Sometimes, different device is selected rather than one you are debugging your app on. Hope this helps.

I had the same problem and solved it in the device developer options by disabling and enabling Usb debugging.

I tried everything. I unintentionally found that empty tags never show. If you are using empty tags, like me, try filling with some letter (blank spaces didn't work for me).

Old question, but the issue seems to occur frequently while running Android Studio 1.1.0. This often happens after I clear all existing log.

When it does, I tap the restart icon (green curved arrow on top of a grey square) and it start working again.

In my case, it usually takes 20 or more seconds for my logcat to display anything. After it does, I see "debugger waiting to settle" messages. This happens every single time.

Try waiting a while to see if it ends up showing up.

Click on the "Debug App" Icon next to the "Run App" Icon or press SHIFT + F9. That seems to do the trick for me.

In logcat, try going to the bottom right corner where there is a ">>" and select that. It restarts it.

Go to "Window -> Preferences"

From the left panel, expand "Android" and select "Logcat". Check if "Show logcat view if message priority is atleast:" is equal to "VERBOSE". If needed, select "VERBOSE" and apply. Now you can see your device events in LogCat.

Try going to developer settings on the phone, and scrolling to the "Monitoring" then "Enable OpenGL Traces" and select LogCat.
