While the answer provided by MoMo will resolve the problem temporarily it will most likely reoccur the next time you launch Eclipse  or launch on a different Emulator Device    Instead of always having to select my device in the devices view I ve found a better solution is to go into your Eclipse preferences and navigate to Android -  LogCat in the list on the left and then enable  Monitor logcat for messages from applications in workspace     This way no matter what device you are using logcat will automatically start showing output from it as soon as the application launches    It will also setup a filter that ensures that only output from your application is displayed  which you can reuse   disable as needed

It gets interesting when you find out that NONE of ALL THE ANSWERS in this thread were helpful   And then you find out that in your version of ADT 22 6 3 v201404151837-1123206 if you add two filters with the same package name application name  then the log will not appear   It was weird because the log was there two seconds ago  and launching the app in debug mode adds a default filter for the app which collides with the filter I ve setup manually  and then ADT magically removes all the log  and NONE of the filter worked including the All messages no filters    I hope I saved someone some time    I was at it for almost an hour        UPDATE       And then I spent another short while figuring that this was masking another issue     I m working with dual screens  the second one is connected via VGA RGB -  not really sure how its called  and what can I do  I m a ton more comfortable with the logcat away from my code editors  so I ve placed it in another window  and as it turns out that is the main reason for the disappearing logs for me

In case if you are using cynogenmod in your mobile it will disable logging by default  try this method   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

I had this same issue but my fix was much more basic   If the LogCat panel is empty in Eclipse 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

User · Answer

OK  This is how I got it to work  I first followed MoMo s advice  that is        If the LogCat panel is empty in Eclipse 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     But to no avail   I then attempted to reset adb  Android Debug Bridge  as suggested by furikuretsu  How  Window -  Devices -  upside down triangle menu button -  Reset adb   It also didn t work  but I did get the following message      Android hierarchyviewer  Unable to get the focused window from device   This meant that MoMo was right in that my Android device or emulator didn t have focus  However  the solution I did in my case is different   What worked for me   1  Replugged my Android device  which was connected to my computer via USB   2  Restarted Eclipse  as mentioned by Abu Hamzah  although since I didn t know I can do File - gt  Restart  I manually closed down Eclipse  and then restarted the application again    I can now see logs in my logcat   Hope this helps you too

Check if the Console is telling you something  Usually this happen when the project could not be install in the device  and just show the previous one  The most common case I has seen this is when there are different signatures in the project  and is not running at all  Please  read all red letter you see  If the LogCat does not show anything  take for sure that the Console will do
