Ud839_miwok: Unable to View Log messages from Logcat

I am in the same boat as you. Did not see any printed log cat messages for the array or for the arraylist.

I think you need to clean up the previous log messages in the logcat by clicking on the bin icon to the left of logcat window and then run the app again.

If you're still not able to find it, try to search for the specific log in the search box of the logcat window.

I decidedto go on with the course, and then later on it started showing. Don't pay too much attention to it. You're good to go!

Kindly close the issue @babsdalley

I am having the same problem.Log message is not coming in Logcat inspite of writing the same code which mam has provided

@sandidutt2 did you tried the above solution?

Also, you can do this:

1. Go to Run -> Edit Configurations
2. Select the Miscellaneous tab and select _Show logcat automatically_ and _Clear log before launch_.
3. Restart

For easily finding your log messages you have to search with the word "NumbersActivity" in the search tab provided in logcat.

There may be one another reason for the log messages not to appear.When you run your project for the ,the logcat will not show the NumbersActivity messages until you click the Numbers button on your device or emulator.
Given below is state of emulator before pressing Numbers button...

Given below is state of emulator after pressing Numbers button.

Closing this issue as it is not related to the repo's code.
