14.4 Filtering the Logcat Panel
The purpose of the code added to the overridden methods in MainActivity.java is to output logging information to the Logcat tool window. This output can be configured to display all events relating to the device or emulator session, or restricted to those events that relate to the currently selected app. The output can also be further restricted to only those log events that match a specified filter.
Display the Logcat tool window and click on the filter menu (marked as B in Figure 14-3) to review the available options. When this menu is set to Show only selected application, only those messages relating to the app selected in the menu marked as A will be displayed in the Logcat panel. Choosing No Filters, on the other hand, will display all the messages generated by the device or emulator.
Before running the application, it is worth demonstrating the creation of a filter which, when selected, will further restrict the log output...
