Sometimes eclipse logcat messages disappear after closing the app for a short time. (Mostly not so short.) How to make it never disappear automatically?
EDIT: My device is still attached. And how to set it to show log even after device disattach and clear just before next launch?

Solution 1: Restarting your Android StudioIn your IDE Go to File > Invalidate Caches and Restart > Invalidate and Restart. This Solution will clear all the caches of Android studio IDE and restart it automatically, By the method, there are 80% change that Logcat will start work as before.
They are stored as circular memory buffers on the device. If you run "adb logcat > myfile" on your host system, you can retrieve the content into a file.
Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log class. This page is about the command-line logcat tool, but you can also view log messages from the Logcat window in Android Studio.
this is also happening with me. The device is attached. And so all the internal actions are getting logged and the error message disappears very quickly. You should try the following (it worked for me)
First one worked for me. In this way also you need not to detach the device everytime you deploy the app from eclipse. Regarding, the other question - you can always clear the existing log from [Clear log] button.
