Eclipse LogCat - Not Working

Question

This is the most frustrating thing ever, LogCat keeps deactivating/disconnecting. After running eclipse, LogCat logs for first run and after that, it goes Blank. I have to restart Eclipse to get it running again, and then same thing happens again. What is matter with it? It used to work fine. I can't recall changes I've made to undo what I (might) have done.

EDIT - Screen of Eclipse as requested.

How many processes are your running ? Are you running your application project in emulator or device ? — Rahul Gupta, Dec 29 '13 at 17:49
have you tried with other devices ? sometimes it's the device that runs crazy — TootsieRockNRoll, Dec 29 '13 at 17:49
I've checked my Device, the Developer options seems all normal. I have also restarted the device, but still same problem. — KickAss, Dec 29 '13 at 17:50

If the LogCat is empty, the emulator doesn't have the focus. Go to the DDMS perspective and try clicking on the 'emulator' entry in the Devices panel (top-left screen).

Same thing with a device. You just have to click on the entry representing that device and the log messages comes.

Under Devices in the DDMS perspective, I only see my Phone Device, no emulator – KickAss Dec 29 '13 at 17:54
So check the phone device. In the logcat, you can see your phone too and maybe you have selected a filter that is why your logcat is empty. – Rahul Gupta Dec 29 '13 at 17:55
LogCat filter is fine too, Even the "All Messages" is empty. – KickAss Dec 29 '13 at 17:56

Also after hitting "Clear Log", when I run the app again, LogCat stays blank. – KickAss Dec 29 '13 at 18:00
Please post a screenshot of your eclipse screen – Rahul Gupta Dec 29 '13 at 18:03
See main post above. Added screen of Eclipse. – KickAss Dec 29 '13 at 18:07
What i can say is that you should update your ADT and logcat, then try again. Maybe you are using an older version of logcat because i have never encountered such an issue – Rahul Gupta Dec 29 '13 at 18:23
Is it possible I am missing some sdk packages? I uninstalled loads of stuff I didnt think I needed. See EDIT 2 in the main post. Am I missing anything important? – KickAss Dec 29 '13 at 18:29
I would suggest that you re-install your eclipse from scratch and only install API 19 or maybe 14 to 19. – Rahul Gupta Dec 29 '13 at 18:39
Okay, will do and post back. Thanks for now – KickAss Dec 29 '13 at 18:40

Most of the time Rahuls method would work, but sometimes even that doesn't work in that case, Kill the ADB and restart the eclipse.

It happens to me also sometimes, why don't you try to run the deprecated logcat from windows-> preference -> logcat again before closing the logcat, let me know if it works. also try to reconnect your phone through usb again. – Yauraw Gadav Dec 29 '13 at 18:47
I will try the reinstall ADT suggestion first, and if it comes to it, use deprecated version. – KickAss Dec 29 '13 at 18:47

I believe this other post with the same problem will answer this:

https://stackoverflow.com/a/11967853/241014

Essentially, set the log's buffer to a higher value by going in Eclipse to Window > Preferences > Android > LogCat. Set the "Maximum number of logcat messages to buffer" to something higher than the default of 5,000.

For Eclipse only when LogCat isn't working:

1 - Open Perspective "DDMS".
2 - On the left side, click on the device you want to monitor.
3 - Change Perspective back to "JAVA".

How on God's green Earth is a person meant to work that out? Bravo Pedro. This fixed it instantly. `Perspective` is in the `Window` menu @ newbies. Thanks again – Onimusha Oct 04 '15 at 01:12

In case if you are using cynogenmod in your mobile, try this:

In your device, open "/system/etc/init.d/" folder If there are many files, try opening each file and find for this line:

rm /dev/log/main

Now, comment this line like this: # rm /dev/log/main

save the file and reboot.

If you close LogCat and re-open it it will display the information.

Although this question has been asked long before, I am answering for others who might stumble upon this trouble.

In Mars, eclipse 4.5 and linux using GTK 3, if Android Logcat display is missing, add the following in eclipse.ini before "--launcher.appendVmargs".

--launcher.GTK_version
