Logcat not displaying my log calls

Question

I\'m a total noob at Android programming, and wanted to learn how to debug my apps. I can\'t seem to have my Log.i|d|v calls displayed in the LogCat.

Answer 1

I've had the same problem using Android Studio and managed to get around by selecting No Filters in the select box in the top right corner of LogCat. By doing this I started receiving everything Android logs in the background into LogCat including my missing Log calls.

Answer 2

I made the mistake of typing in a search term in the logcat search box. I forgot to delete it and hence couldn't see the new logs. Since they didn't match my search term and weren't displayed.

Answer 3

In my case, I had to remove this line:

    <application
         android:debuggable="false"  <!-- Remove this line -->
         ..../>

From Application tag in my Manifest file.

Answer 4

If all else fails:

I did all the above things and couldn't figure out what was wrong,

Test with:

adb logcat

Answer 6

I spent several hours on such case. I saw only touch keys logs. Nothing more. Problem was... smarthphone. After restarting was OK. Disconnecting cable caused problem returned. Had to restart it again. Looks like the Android USB communication is not well designed.
