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 resta

Answer 1

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.

Answer 2

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".

Answer 3

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

Answer 4

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

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.

Answer 5

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

Answer 6

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.
