The default display of the logcat output in the Android Monitor window at the bottom of Android Studio is often not very useful because it has limited display space and a large volume of information scrolls through it by default. In this example the output has been selectively displayed by choosing Info (meaning only Log.i messages), Show only selected application, and filtering so that only lines containing the string "Webscreen" are displayed.Ī more extensive discussion of using Android Studio to view and filter logcat messages may be found in In the following figure Android Studio is displaying output from LogCat in the Android Monitor panel at the bottom (note that the logcat tab has been selected).
